  • Performance Evaluation of Lablab Genotypes across Various Locations of

    • Abstract: This study was conducted evaluate the performance of Lablab genotypes across various locations of Ethiopia. Twelve accessions of L. purpureus obtained from ILRI Genebank and a check registered variety from Bako Agricultural Research Center were sown under a 3 × 13 factorial experiment in a randomized complete block design (RCBD) during the rainy season in 2020, across three locations, namely Tepi, Bechi, and Kite sites of South West Ethiopia. The data were collected on the establishment, days to different physiological stages, forage yields, soil properties, and other related parameters. The data were subjected to analysis of variance using the general linear model of SAS and mean comparison via list significance difference test. A significant difference () was observed across locations for most of the studied agronomic traits. The highest average dry matter (DM) forage yield recorded for T6 (accession 11613), T8 (acc. 10953), T5 (acc. 14417), and T4 (accession 11612) was 10.3, 8.7, 6.8, and 7.4 t/ha-1, respectively. Dry matter forage yield was positively associated and regressed with plant height and leaf-to-stem ratio. Lablab accessions are well adapted to the ecology tested. Lablab could also be produced in these locations without any remarkable disease problems. It is recommended that five top forage producing accessions be advanced for the next step of yield evaluation in standard multilocation. This leads to recommending best lablab accessions to be registered for the Tepi area and other similar agroecologies. Furthermore, recommended varieties should be evaluated through animal performance through feeding trials. Refining the main agronomic practice such as time of sowing, application of fertilizer, harvesting time, identifying best food crop-lablab integration methods, and feeding strategies is also vital to address in the future.

  • Effect of Tillage Method and Mulch Application on Growth and Yield of
           Green Gram in Semiarid Kenya

    • Abstract: Conservation tillage is regarded as the best practice for crop production in drylands. However, their effect on the green gram (Vigna radiata (L) Wilczek) has not been much documented in ASALs of Kenya. A field study was conducted during the 2018-2019 short rains with the aim of evaluating the effect of tillage methods and mulch application on the growth and yield of two green gram varieties in Katumani and Mwea. A randomized complete block design (RCBD) with a split-slit plot arrangement and three replicates was used. The main plots were tillage methods zero tillage (ZT), furrow-ridge (FR), and conventional tillage (CT). Subplots were mulched plots with plant residue (3 t·ha−1) and plots without mulch applied (0 t·ha−1) and in the sub-subplots were two green gram varieties (N26 and KS20). Data was collected on plant height, number of primary branches, root biomass, shoot biomass, number of pods per plant, number of seeds per pod, 1000 seed weight, grain weight (t·ha1), and harvest index. Data was subjected to the general analysis of variance using GenStat 15th statistical software. Mean separation was calculated using the least significant difference LSD at a 5% probability level. Results showed that tillage methods and mulch application significantly affected growth, yield, and yield component. Furrow-ridge recorded superior effects ahead of zero tillage and conventional tillage. Mulch application had significant effects on growth, yield, and yield component. Variety N26 under the treatment of furrow-ridge mulched with 3 t·ha−1 had a greater number of branches, plant height, yield, and yield components in both experiment sites. The application of mulch had a positive impact on growth, yield, and yield component. Furrow-ridge and zero tillage with mulch emerged to be the most efficient techniques for better green gram yield in Katumani and Mwea. This can be recommended for increased crop production in areas that receive insufficient rainfall.

  • Management of Major Seed-Borne Fungi of Cowpea (Vigna unguiculata (L.)
           Walp) with Four Selected Botanical Extracts

    • Abstract: Seed-borne fungal pathogens present significant constrain to the production and conservation of many seed crops including cowpea. Infection of mature seeds by such pathogens could result in mycotoxin contamination, loss of viability, and decay of seeds. This study aimed to identify seed-borne fungi on 200 accessions of cowpea under cold storage at CSIR-Plant Genetic Resources Research Institute (PGRRI), Ghana. Also, the antifungal effect of seeds of Piper nigrum, Xylopia aethiopica, Aframomum melegueta, and fresh leaves of Cymbopogon citratus aqueous extracts (100% w/v) on the major seed-borne fungi identified on the cowpea seeds was determined. Seven fungal species belonging to five genera were identified from the seeds of the cowpea accessions evaluated. However, the diversity and infection levels of the pathogenic fungi recorded on the seeds were lower than that of the saprophytic fungi indicating minimal capacity of the seeds to spread pathogenic fungi on the field. Aqueous extract of Aframomum melegueta inhibited the growth of Fusarium verticillioides by 98.40%, Colletotrichum sp. by 97.83%, Aspergillus niger by 94.70%, and Aspergillus flavus by 63.38%. The only other aqueous extract that inhibited the colony growth above 60% was that of Piper nigrum which inhibited colony growth of Fusarium verticillioides by 71.7% and Colletotrichum sp. by 63.47%. Due to the benign effect of Aframomum melegueta extract on the environment and non-target organisms, its use as a seed protectant is highly recommended. Further studies to establish the spectrum of activity and dose levels of Aframomum melegueta extract are recommended.

  • Evaluations of Different Seed-Dressing Fungicides with Chickpea Varieties
           for the Management of Fusarium Wilt in Eastern Amhara, Ethiopia

    • Abstract: The disease fusarium wilt is a serious and infectious year-round disease in chickpea-growing areas and causes huge chickpea yield losses. Thus, this research study was initiated with the objective of evaluating different seed-dressing fungicides with different chickpea varieties for the management of fusarium wilt (Fusarium oxysporum f.sp. ciceris) in Eastern Amhara, Ethiopia. Field experiment was conducted in hot spot areas of two locations using the material: two moderately resistant and one local (susceptible check) chickpea varieties with three commercially available seed-dressing fungicides (Apron Star, Noble, and Thiram). Treatments were arranged factorially in the RCB design with three replications. Results depicted that moderately resistant Mitk variety has significantly reduced disease pressure and gives better yield as compared to Arerti and local chickpea varieties. Even the disease pressure of fusarium wilt was lower in the Mitk variety followed by Arerti, and hence, its incidence and area under the disease progress curve reveal 6.23% and 292.1%-day, which was far apart by 17% and 873%-day, respectively, from Arerti. In case of the local chickpea variety, it was highly infected and its seed yield (0.4 t/ha) was lowered almost by half from the Mitk variety. Despite seed-dressing fungicides showed insignificant difference in both incidence and area under the disease progress curve, Thiram seed-dressing fungicides followed by apron star on Mitk variety indicates reasonable yield increment in both locations. Hence, integration of Mitk chickpea variety with the corresponding Thiram seed-dressing fungicides followed by Apron Star was advisable to manage fusarium wilt disease.

  • Assessment of Status of Climate Change and Determinants of People’s

    • Abstract: This study aims to analyze the status of climate change and determinants of people’s awareness of climate change in Sarlahi district, Nepal. A total of 102 respondents were selected randomly from the study area and interviewed using a semistructured questionnaire from May 12, 2021, to May 23, 2021. Along with the determinants, this survey emphasized finding climate-smart alternatives favoring not only the population or sectors like agriculture but also the climate itself. The chi-square test was conducted to measure the relationship between the operational variables, which revealed that there was no significant relationship between gender and knowledge of climate change, occupation and knowledge of climate change, land ownership and knowledge of climate change, guardian and knowledge of climate change, and decision role and knowledge on climate change. However, education, family size, and age had a significant effect on the knowledge of climate change. The binary logit model reported that age, years of schooling, training related to climate change, and involvement with cooperatives were found to have a significant effect on people’s awareness of climate change. Thus, improving people’s adoption of climate-smart agriculture in the education system of the study area and training the people in the study area should be a prime concern.

  • Propagation of Theobroma cacao by Rooted Cuttings in Mini-Tunnels

    • Abstract: Cacao is an economically important crop that is currently planted in Asia, Africa, and America. Cuttings is a technique of vegetative propagation suitable for the conservation of selected desirable characteristics in cacao trees. The objective of this study was to evaluate the rooting of cacao cuttings in mini-tunnels with different doses of indole-3-butyric acid (IBA) to obtain a simple and viable vegetative propagation protocol. The experiment was carried out under a completely randomized design (CRD). Cuttings 5 to 7 cm long were collected from the middle area of cacao tree crowns and treated with doses of 0, 1000, 2000, and 3000 ppm of IBA; then they were placed in Jiffy© pellets and set to root in plastic-covered mini-tunnels with fog irrigation. The results indicate that treatments with 0 and 1000 ppm of IBA produced the highest values in survival (100%, both treatments) and rooting percentage (87.7 and 90.0%, respectively) as well as number and length of roots (4.3 roots-4.21 cm in length and 4.5 roots-5.32 cm in length, respectively); likewise, cuttings treated with 0 ppm rooted after 24–40 days, followed by doses of 1000 ppm (24–46 days). All rooted cuttings without IBA (0 ppm) achieved 100% acclimatization in nursery. In general, the best results were obtained without IBA application (Control 0 ppm) in all the parameters evaluated, similar to those obtained with the application of 1000 ppm IBA; these results indicate the success and efficiency of the vegetative propagation protocol proposed in this study.

  • Farmers’ Perception on the Welfare of Broiler Chickens in Smallholder
           Production Systems in Kiambu County, Kenya

    • Abstract: In Kenya, commercial broiler production is growing rapidly due to increasing demand for poultry meat resulting in higher incomes for farmers. Due to this increase in demand, broiler chicken production is increasingly becoming intensive where chickens are overstocked in deep litter systems subjecting the birds to suffering perpetuated through burns on their shanks and breasts with constant footpad lesions, thus compromising their welfare. This study was conducted to determine the farmers’ attitudes towards the welfare of broiler chickens in smallholder production systems in Kiambu County, Kenya. A total of 120 farmers were randomly chosen for the study consisting of 42 and 78 respondents from Kikuyu and Kabete subcounties, respectively. A semistructured questionnaire was used to interview the farmers on their knowledge, attitudes, and practices in regard to broiler welfare. The results of this study indicated that most farmers (74%) in Kikuyu and Kabete subcounties had knowledge about broiler welfare. Media, hatcheries, agrovet centres, and extension agents were the main sources of information on broiler welfare to farmers at 61%, 40%, 38.8%, and 31.5% respectively. Farmers perceived that good feeding (88%), good health (83%), suitable housing (82%), and appropriate behaviour (48%) were very important indicators of broiler chicken welfare. Gumboro (infectious bursal disease) and new castle disease (NCD) were prevented through vaccination by most farmers (91%), while coccidiosis was controlled through cleaning and disinfection of broiler sheds and equipment as well as treatment of sick birds with coccidiostat. In conclusion, farmers’ perception on broiler welfare has a bearing on the performance of broiler chickens.

  • On-Farm Diversity of Enset (Ensete ventricosum (Welw.) Cheesman)
           Landraces, Use, and the Associated Indigenous Knowledge in Adola Rede
           District, Guji Zone, Oromia, Ethiopia

    • Abstract: Background. Enset (Ensete ventricosum (Welw.) Cheesman) is an important staple crop for more than 20 million people in Ethiopia. Precise ethnobotanical information of intraspecific enset diversity and local knowledge on how farmers maintain, manage, and benefit from enset genetic resources is imperative for the promotion, conservation, and improvement of enset and its farming system. The aim of this study was to identify and document the wealth of indigenous knowledge associated with the distribution, diversity, and management of enset in Adola Rede District. Methods. The study was conducted in Adola Rede District of Guji Zone, Oromia, Ethiopia. To identify and document the wealth of indigenous knowledge, the data were collected mainly through individual interviews and observation with 139 farm households and key informant interviews. Results. Thirty-four landraces were identified. The number of landraces cultivated in individual households ranged from 3 to 14 (mean of 6.08 ± 2.17). The farmers distinguish landraces primarily using morphological features such as pseudostem color, midrib color, plant height, and leaf color. Agronomic characteristics such as resistance to disease and pest and maturity time were secondary criteria for the identification of enset landraces in the study area. Enset is mainly used as food (kocho, bulla, and amicho) and source of fiber, and it has also medicinal value for both humans and livestock. Farmers prefer a landrace to the other, for example, Gantichoo for worqee (kocho) and fiber, Adoo for budhaa (bulla), Nimfoo for amicho, and Astaraa for medicinal use. The majority of the informants (74.10%) have got their plant material by multiplying planting material by themselves, exchanging with neighbors (16.50%), and purchasing from the market (9.40%). Conclusion. There was relatively high on-farm enset landrace diversity, and the indigenous people had a long tradition of enset cultivation, conservation, and maintenance of landraces in the district. The information is crucial for developing community-based complementary in situ and ex situ conservation strategies to foster conservation of enset genetic resources and associated indigenous knowledge system.

  • Review on the Impacts of Community-Based Ecotourism on Household Financial
           Asset Improvement and Its Determinants in Ethiopia

    • Abstract: Community-based ecotourism has been recognized as an important factor for households’ livelihood. Rural households normally have a problem of getting access to participate in ecotourism activities and making family better livelihood status in rural areas. The paper was aimed to review the impacts of community-based ecotourism on household financial asset improvement and its determinants in Ethiopia. Community-based ecotourism has been contributing to employment and income-generating activities. To achieve this objective, the published journal articles and reports were reviewed. As empirical review indicates that, institutional factors such as access to training and distance to the park, economic factors such as annual income, and demographic factors determine the participation of households in community-based ecotourism in Ethiopia. Therefore, the tourism extension expert should create awareness for local communities towards participation in community-based ecotourism in Ethiopia.

  • Efficacy of Hexanal Field Spray on the Postharvest Life and Quality of
           Papaya Fruit (Carica papaya L.) in Kenya

    • Abstract: Papaya is a thin-skinned fruit that ripens and softens over a very short time, usually in 3 days, predisposing the fruit to physical damage and phyto-pathogen invasion even with careful handling further shortening postharvest shelf life. The objective of this study was to determine the efficacy of Hexanal, naturally occurring compound, on-farm spray, in managing the postharvest shelf life of papaya in two agro-ecological zones in Kenya. A formulation of Hexanal containing Tween 20 and ethanol was made by volume basis (v/v) and spray treatment at 1 and 2% in “Solo sunrise” and “Mountain” papaya cultivars. The experiment was a randomized block design with ninety-six plants per farm randomly selected. Spraying was applied at 30 days, 30 + 15 days, and 15 days to harvest time on mature green papaya. Control papaya fruits were sprayed with clean tap water as control. Data were collected on color changes and fruit retention on tree. The fruits were harvested when two to three yellow stripes were visible from the lower end of the fruits for postharvest analysis. Hexanal sprayed papaya fruits were retained for at least 13 days longer compared to the control fruits on tree. Hexanal treatment at 2% revealed an improved effect on managing papaya postharvest shelf life. All fruits treated with Hexanal significantly showed reduced rate of color break, softening, and enhanced extension of fruit shelf life by at least 6 days. Hexanal treatment also delayed ethylene and respiratory peaks by three days and showed no significant () difference in the levels of total titratable acidity and total soluble solids. The results of this study indicate that Hexanal applied as a preharvest spray on mature green “Solo sunrise” and “Mountain” papaya cultivars grown in Kenya, is effective in prolonging shelf life and postharvest quality.

    • Abstract: The study was conducted to determine the effect of different grass species (Brachiaria mutica, Desho, and Napier) and harvesting stages on agronomic performance, forage dry matter yield, and chemical composition. The grass species used were Desho (Pennisetum pedicellatum), Brachiaria (Brachiaria mutica), and Napier (Pennisetum purpureum), and the harvesting stages considered were 60, 90, and 120 days after establishment of grasses, respectively. The data collected included the following: percent plant survival (PS), plant height (PH), number of tillers per plant (NTPP), number of leaves per plant (NLPP), leaf length per plant (LLPP), leaf width per plant (LWPP), number of nodes per plant (NNPP), leaf-to-stem ratio (LSR), dry matter yield (DMY), and chemical composition of the grass species. Samples of grass species were harvested at different ages after establishment, weighed, and dried, and then, ground subsamples were taken for determination of dry matter (DM), ash, organic matter (OM), crude protein (CP), crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), and acid detergent lignin (ADL). Results showed that morphological characteristics, forage dry matter yield, and chemical composition of the forage grasses were significantly affected by interactions of species () and harvesting dates. The highest mean PH (115.2 cm), DMY (11.8 t/ha), and %CP (11.6) were recorded from Brachiaria mutica grass which was followed by Napier grass with mean PH of 87.25 cm and mean DMY of 9.8 t/ha. The %CP content of Desho and Napier grasses declined by 24%, while %CP content of Brachiaria grass declined by 26% with increased harvesting stages. Therefore, among tested grass species, Brachiaria mutica grass was recommended followed by Napier and Desho grass for on-farm evaluation and demonstration in the study area at all harvesting ages. Farmers engaged in forage grass production could seriously consider the harvesting stage as the grasses responded differently to the chemical composition.

  • Effect of Sorghum-Mung Bean Intercropping on Sorghum-Based Cropping System
           in the Lowlands of North Shewa, Ethiopia

    • Abstract: Due to decreasing land units and a decline in soil fertility, integrating mung beans into the Sorghum production system is a viable option for increasing productivity and producing cash crops. The experiment was conducted during the 2017 and 2018 cropping seasons in order to evaluate the effect of a Sorghum-mung bean intercrop arrangement on a Sorghum-based cropping system that would maximize intercropping advantage without reducing Sorghum performance. The treatments were combinations of sole Sorghum, sole mung bean, one Sorghum by one mung bean row (1 : 1), one Sorghum by two mung bean rows (1 : 2), two Sorghum by one mung bean row (2 : 1), and mixed planting of Sorghum and mung bean (50/50), which were tested in a randomized complete block design replicated four times. The highest yield reduction was observed from intercropping mixed planting (15.63%), in addition, the mean intercropped Sorghum yield showed up to12.44% reduction compared to sole stand. On the other hand, best-intercropped Sorghum yields that were produced under combinations of 2 : 1 row arrangement (4.11 t·ha−1) gave a statistically similar yield to all combinations including sole stand (4.48 t·ha−1). Significant row arrangement effect showed that the row (1 : 2) gave the highest yield for mung bean (0.35 t·ha−1), while the lowest was recorded from row arrangement (1 : 1) (0.16 t·ha−1). The highest total LER was obtained at 1 : 2 row (1.23) arrangements. The highest net return and marginal return (MRR) (341.23%) was obtained from one-row Sorghum alternated with two-row mung bean (1 : 2). Therefore, farmers around the research area can get additional income from intercropping Sorghum with bean crops without adversely affecting Sorghum yield by using one-row Sorghum alternated two-row mung bean (1 : 2) row arrangement.

  • The Indirect Threats of Desert Locust Infestation on Honeybees in Ethiopia

    • Abstract: This review focuses on the potential effects of a desert locust infestation on Ethiopian honeybees. Data on the country’s infestation, locust activity, honeybee foraging behavior, pesticide kinds, and application rates were collected and analyzed in connection to honeybee life and performance. Desert locust has damaged a considerable number of plants of various kinds, possibly causing pollen and nectar loss. As a result, honeybees are likely to produce less brood, less honey, suffer from poor health, and abscond. Besides, studies suggested that the use of pesticides to control the locust could directly harm honeybees. The pesticide was used for 21 days in a row to cover a huge region infected with locusts, which could have had a severe effect on honeybees. The probability of an influence is also indicated by the overlap of pesticide administration with honeybee foraging seasons and hours. Furthermore, forager bees leave their hive 1 to 13 times per day, spending about 3 hours outside each time, indicating higher chemical exposure. Malathion is one of the pesticides that could harm honeybees, while there is no comprehensive list of the chemicals used on the internet or anywhere else. Finally, the current desert locust invasion and eradication operation in Ethiopia may have caused substantial damage to honeybees as a result of bee forage loss and pesticide hazard, emphasizing the need for future precautions. Because this is speculative work based on evidence, detailed survey research is recommended to determine the actual impact imposed on honeybees.

  • Performance of Doubled Haploid Elite Rice (Oryza sativa L.) Germplasm for
           Grain Yield and Associated Traits in Harare, Zimbabwe

    • Abstract: A field experiment was conducted in 2018/2019 growing season at the Scientific Industrial Research and Development Center under irrigated conditions using the simple alpha lattice (77) design, with three replications. The objective of the study was to determine the performance of 44 elite rice lines that were selected and shared from elite doubled haploid germplasm and five cultivars were used as checks. All evaluated genotypes exhibited significant variation in the traits measured except for number of grains/panicle, total tillers/plant, and effective tillers/plant. Elite line 70462 was found to be the highest yielding, with yield advantage of 66% over the high yielding local check (Nerica 7). High values for broad sense heritability were recorded for days to 50% heading, panicle length, culm length, number of filled grains/panicle, 1000-grain weight, grain length, grain shape, and grain yield and indicated lesser influence of environment in expression of these traits, hence amenable to simple selection. Correlation analysis revealed that grain yield manifested significantly positive correlation with filled grains/panicle contributing the highest correlation (r = 0.784), followed by culm length (r = 0.605), spikelet fertility/panicle (r = 0.677), grain length (r = 0.551), 1000-grain weight (r = 0.518), panicle length (r = 0.449), and number of grains/panicle (r = 0.328). Based on grain yield, number of filled grains/panicle and spikelet fertility/panicle, panicle length, and earliness, lines 70462, 60143, 70383, Arica 3, Sahel 177, 6040, 70537, 60409, and 70476 had the best performance. Selection of these traits would be more effective for yield improvement in rice and these promising lines could be used in the varietal development and can be tested in multilocational trials and on-farm trials in Zimbabwe with the possibility of release and commercialization.

  • Growth and Tolerance of Sesame (Sesamum indicum L.) Varieties to Pre and
           Postemergence Graminicides

    • Abstract: The use of herbicides for weed control in arable crop production is known to be fast and effective. However, there is paucity of information on the safety of commonly used grass herbicides on emergence, growth, and productivity of sesame (Sesamum indicum L.) genotypes currently being grown in Zimbabwe. A study was carried out in Zimbabwe during the 2017/18 cropping season in Gokwe South to evaluate the effect of alachlor, metolachlor, propaquizafop, and fluazifop-p-butyl on seed germination, growth, and yield of three sesame genotypes, namely, IETC, Lind 02, and Ziada 94. A laboratory experiment was laid in a completely randomised design with genotype and herbicide type as the factors. Seed germination, radicle, and plumule length were recorded at the end of the experiment. In the pot studies, two separate experiments were carried out to evaluate the effect of pre and postemergence herbicides on 50% emergence, plant height, number of branches, 50% flowering, number of pods, and yield of three sesame genotypes. The laboratory experiment results revealed significant () interactions among varieties and preemergence graminicides for germination percentage, radicle length, plumule length, and germination vigor index. Alachlor and metolachlor differentially reduced all germination parameters in the sesame genotypes used in the study. In the preemergence pot studies, there were significant () interactions on 50% emergence, plant height, and number of branches but not on number of pods and yield. Metolachlor significantly reduced all the measured parameters in IETC and Ziada 94. In the postemergence pot study, propaquizafop significantly () reduced plant height, number of pods, and yield of sesame more than fluazifop-p-butyl and hand pulling. It can be concluded that metolachlor and propaquizafop are not safe for use in these sesame genotypes at dosage rates that were used in this study. There is need for further screening of more sesame genotypes for tolerance to these and other commonly used genotypes to avoid unintentional phytotoxic damage on sesame.

  • Cyst Nematode (Heterodera glycines) Problems in Soybean (Glycine max L.)
           Crops and Its Management

    • Abstract: Soybean is a leguminous crop that originated from Southeast Asia, and it was domesticated in the northeastern parts of China. Recently, it has been highly produced in the United States of America, Brazil, and Argentina for cooking oil, protein, fiber and for the manufacturing of plastics, lubricants, candles, varnishes, soaps, and biodiesel. Nevertheless, in warm, moist, sandy soil conditions, its production is highly challenged by soybean cyst nematodes (Heterodera glycines). It caused more than 30% of soybean yield loss either alone or associated with other soybean pests under suitable environmental conditions. The second-stage juvenile (J2) of this pest inserted its stylet and penetrated into the cells to get its nourishment, shelter, and reproduction site on the soybean roots. Economically, the damage it caused was highly important because it had a wide host range and lacked adequate management methods. Hence, the reason behind the writing of this chapter is to explore the different published scientific papers related to soybean cyst nematode’s economic importance, distribution, symptoms, biology, life cycle, interaction with other pathogens, different management approaches, and its prospects. This chapter shall also embrace the advanced biotechnological innovations that help in achieving effective soybean cyst nematode management that will mitigate its infections in soybean production and will also serve as an asset for the researchers. This review chapter, in addition, plays a vital role in exploring necessary information concerning soybean cyst nematode management.

  • Effects of Harvesting Times and Germplasm Accessions on the Physical
           Properties of Roselle (Hibiscus sabdariffa L.) Seeds

    • Abstract: Roselle (Hibiscus sabdariffa L.) is an important crop grown successfully in tropical and subtropical climates with huge nutritional, economic, and industrial benefits. The physical properties of seeds, particularly length, width, thickness, mean diameter, angle of repose, degree of sphericity, mass, and surface area, have been found to play significant roles in designing equipment for storage, transportation, and subsequent field operations of the seeds. Therefore, a study was carried out to determine the effects of different harvesting times on the physical properties of seeds of twelve roselle accessions for their subsequent industrial management. In total, 12 × 3 factorial arrangements in Randomized Complete Block Design and Completely Randomized Design were used for the field and laboratory experiments, respectively. The first factor was germplasm accessions at twelve levels (HS08, HS11, HS19, HS25, HS27, HS32, HS41, HS58, HS59, HS69, HS83, and H86), and the second factor was harvesting times at three levels (physiological maturity, one week after physiological maturity, and two weeks after physiological maturity). Seeds of accession HS32 harvested at the physiological maturity stage had the highest moisture content, which was similar to the other 11 accessions harvested at the same stage. The seeds of accession HS08 harvested at physiological maturity had significantly the best values in seed length (4.33 mm), seed width (4.30 mm), seed thickness (2.43 mm), seed geometric mean diameter (3.83 mm), seed angle of repose (20.57°), seed sphericity (0.76), seed surface area (18.57 mm2), and seed mass (0.05 g). Further, there were strongly positive and significant correlations between seed width and seed angle of repose (r = 0.93); seed width and seed length (r = 0.84); seed width and mean seed diameter (r = 0.89); seed width and seed sphericity (r = 0.68); seed width and seed surface area (0.94). There were also strongly positive and significant correlations between seed thickness and seed sphericity (r = 0.79) and also between seed thickness and seed surface area (r = 0.63). In conclusion, the physical properties of accession HS08 harvested at the physiological maturity stage could be very important in designing machinery for roselle seeds storage, transportation, and subsequent field operations.

  • Determinants of Livelihood Diversification among Households in the
           Sub-Saharan Town of Merawi, Ethiopia

    • Abstract: Livelihood diversification could be determined by complex and diversified factors. Yet, unlike the rural areas, the situation is unexplored in the case of towns of developing economies. The objective of this study was to identify the determinants of households’ livelihood diversification in a sub-Saharan town. Data were collected from 151 households and 4 key informants. In addition, secondary data were collected to supplement the primary data. Descriptive statistics were employed to identify the households’ livelihood strategies. The level of households’ livelihood diversification was estimated by the Herfindahl–Hirschman Index, whereas multinomial logistic regression was employed to investigate the determinants of the households’ livelihood diversification. The result of the Herfindahl–Hirschman Index shows the presence of three levels of livelihood diversification among households: no diversification (11.26%), moderately diversified (26.49%), and highly diversified (62.25%). The model analysis revealed that out of eighteen predictor variables, only seven variables, namely, total cattle possession (B = 0.329, ), land ownership (B = 120.572, ), income from irrigation (B = 2.902, ), total annual cash income (B = 0.000, ), price fluctuation problem (B = 2.899, ), market price fluctuation plus total cattle possession (B = 12.892, ), and no price fluctuation plus total cash income (B = 0.000, ) were found significantly influencing households’ livelihood diversification. Households in the study town are engaged in different livelihood diversification strategies rather than relying on farm only for improving their wellbeing, and livelihood diversification was gaining a dominant role in households’ income. Even if the Ethiopian agricultural policy gives more attention to the agriculture sector, there is evidence that households’ income is not limited to agriculture. Therefore, nonfarm livelihood diversification should be strengthened by government initiatives to sustain households’ livelihood diversification.

  • Rootstocks for the Management of Bacterial Wilt in Eggplant (Solanum
           melongena L.) and Tomato (Solanum lycopersicum L.) in the Coastal Regions
           of India

    • Abstract: Cultivation of solanaceous vegetables such as eggplant and tomato is severely affected by bacterial wilt in the coastal regions of India. The causal agent Ralstonia pseudosolanacearum is soilborne bacterium, highly diverse, and able to survive in soil for many years without a host. Five bacterial wilt resistant eggplant (Solanum melongena) rootstock lines were evaluated by challenge inoculation and were found to show different levels of wilt incidence. Grafts of eggplant made on two rootstocks (S0004 and Surya) recorded reduced incidence of bacterial wilt (10 to 40%) during greenhouse evaluation while in nongrafted seedlings, the wilt incidence was 80 to 100%. Field evaluation of eggplant grafts made on Solanum torvum (Turkey berry), S0004, and Surya reduced the incidence of bacterial wilt compared to nongrafted seedlings. The lowest wilt incidence (0 and 15–40%) was observed in the field evaluations where S. torvum was used as rootstock, while the nongrafted control recorded 93–100% wilt. Tomato seedlings grafted on S. torvum, Surya, and S0004 recorded very low bacterial wilt incidence (0 to 15%) under greenhouse evaluation while the nongrafted seedlings recorded 80 to 100% wilt. Reduced bacterial wilt incidence (23 to 40%) was observed in grafts of polyhouse-grown tomato hybrid (GS-600) made on S. torvum while the nongrafted seedlings were severely affected (80 to 100%) in evaluation trials conducted for two years. From this study, it is evident that grafting of susceptible eggplant and tomato on resistant rootstocks, viz., S. torvum and Surya, could be a promising strategy in bacterial wilt management.

  • Performance Evaluation of Boer × Central Highland Crossbred Bucks and
           Farmers’ Perceptions on Crossbred Goats in Northeastern Ethiopia

    • Abstract: The study aimed to characterize the production system, to evaluate the genetic merit of Boer × Central Highland crossbred bucks, and to solicit the perception of farmers about crossbred goats and crossbreeding program. Data were collected through a personal interview, focus group discussion, field observation, and measurement of the live animal. Besides, data on growth performance were extracted from available performance records at Sirinka sheep and goats breeding station. Data were analyzed using SAS, and the breeding values for bucks were estimated using WOMBAT software. Goats were the second most important animal species, and income generation, home meat consumption, and saving were found to be the main reasons for keeping goats with index values of 0.484, 0.355, and 0.085, respectively. The production system was characterized as a low-input production system. Feed shortage and disease/poor veterinary service were the most important constraints for the goat crossbreeding program. The overall mean estimated breeding values (EBV) for three- and six-month weight of disseminated crossbred bucks were 0.53 and 0.31 kg, respectively. The three-month weight EBV for crossbred goats disseminated in Amhara Sayint and Habru district was lower than their contemporary group. Likewise, the six-month weight EBV for crossbred goats distributed in Amhara Sayint was lower than the contemporary group mean. These results depict the absence of buck selection based on their genetic merit. As per farmers’ perception, crossbred goats were superior (odds ratio = 3.94 to 20.9, ) to indigenous goats in terms of production traits. Besides, the price of the crossbred goat was higher (213 to 372 ETB/head) than indigenous goats with similar management and age. However, poor adaptability and fitness were the major demerits of Boer × Central Highland crossbred goats under a smallholder management system. Therefore, while introducing exotic breeds, it is imperative to give due attention to nutrition and veterinary service.

  • Challenges and Opportunities for the Agricultural Producers in Sinana
           District in Reflection of COVID-19 Pandemic

    • Abstract: Introduction. Analyzing the effect of COVID-19 is an important issue in agricultural sectors. However, such analysis requires a complex hierarchical statistical model. Rapid spread of the COVID-19 pandemic has disrupted the world’s production and productivity in many sectors. Among those sectors, the agricultural sector is highly affected. The Bale zone in the larger extent and Sinana district, in particular, is one of the potential agricultural areas in the Oromia regional state, Ethiopia where agriculture is the major sector in supporting the livelihood of thousands of subsistence farmers in the area as well as the country at large. Research Methodology. This study involved primary data collected from the farmers in the Sinana district during the period 2020–2021. A total of 991 farmers were selected from the entire 22 kebeles in the district. The data were analyzed using multilevel binary logistic random intercept regression models with maximum-likelihood parameter estimation. Results. Of the 991 farmers, 549 (55.4%) responded that COVID-19 has brought only challenges in their agricultural production and 311 (31.4%) responded both challenges and opportunities. About 632 (63.8%) of the farmers said that there was wastage of products such as milk, dairy, fruits, and vegetables. Three hundred twenty-eight (33.1%) of the participants obtained modernization in their agricultural production system like use of tractors and irrigation systems. According to the model results, farmer’s sex, age, educational level, family size, farmland size, types of effect, aggravation in food insecurity, input delay, lack of workers, slowdown of service, falling in income, modernization in the system of production, wastage of product, and types of wasted products were identified as significant factors. About 8% of the total variability in the effect of COVID-19 is due to differences across kebeles (ICC = 0.08, value ≤0.05), and the remaining is due to individual differences. Conclusion. This study further demonstrated the potential of a hierarchical model for the study of COVID-19 effect variation within and between the kebeles. The majority, about 92% variation in the effect, is due to the disparity of individuals (farmers). The farmers with large family sizes and high capacity to produce and who were females were negatively related to the effect of COVID-19 in agricultural production.

  • Different Aspects of Weed Management in Maize (Zea mays L.): A Brief

    • Abstract: Maize yield and weed concentration have a long history of reciprocal correspondence. The maize crop plant and weed species compete ruinously for nutrients, space, light, and water essential for their progress and advancement. The losses due to weed and methodologies of weed management have been discussed in this review. Reports have estimated around a 37% global loss in total maize production due to weeds. Among the different available weed control methods, chemical methods have become the new common in today’s world. A major upswing in interest in chemical methods of weed control from people all over the world can be deduced from surveys. The monetary forces that are the foremost objectives guiding our choices in crop production practices play a major role in this stimulation of increasing interest. These changes are not in the least befitting for the long term, as the overexploitation of the herbicides has an adverse effect on the environment and causes dismissal of the productivity of the soil, although being market-driven and favorable in the beginning. Since none of the single approach methods can work well enough on maize crops, integrated weed management and biological methodologies are recommended through several reports. In contrast to various weed management strategies, a significant gain in the academic attention of biological control methods can be reckoned from reports over the past few years. Many research projects are also currently underway.

  • A Review of Sensor Technologies Applicable for Domestic Livestock
           Production and Health Management

    • Abstract: The world is running for the digitalization of social, economic, and political endeavors. As the world is getting into technologies of various streams of development, agriculture, especially livestock production, is also one of the areas of development that requires the application or use of emerging technologies. But knowledge and skill are relatively scanty, particularly in developing countries. Hence, it is vital to fill this gap of knowledge by compiling information and presenting it to a large audience for further research in the field. In the era of the advent of sensors for broader fields, it is important to consider the possible application of these technologies in rangeland condition assessment and animal production. The technologies are more relevant in the implementation of precisions farming practices of livestock including the individual animal behavior, grazing condition, health condition, and forage intakes. For grazing stock, it is vital to assess the status of both livestock grazing behavior and rangeland resource conditions. The rangeland resources are important components of livestock production throughout the world. Forages and pasture are dynamics in the abundance, species composition, and chemical composition as a result of environmental and management changes. The rangeland resources must be assessed and monitored for better management and utilization. Conventional assessments which include manual or mechanical counting, identification, and chemical composition are laborious and time-consuming. Under field conditions, not only grazing lands condition can be monitored using sensors but also is possible to understand the grazing behavior of animals for better management of grazing stock. To complement and or replace conventional techniques, it is vital to understand the current technologies such as sensors or biosensors. This review study is organized to increase awareness of the available technologies and their relevance regarding rangeland resources, particularly in tropical rangelands. In most cases, in the tropics, GPS systems are commonly used to assess only the rangeland status without considering the grazing stock. The review also elucidates that sensor technologies are important to detect livestock health conditions and movements at the field level in a rapid and easy way. However, like other technologies, sensors (biosensors) have limitations including accuracy of measurements and repetitive data accusations. Nevertheless, the review elucidates the use of sensor technologies and saves time and energy in animal production which otherwise could demand extensive energy and time.

  • Economic Viability and Use Dynamics of the Enset Food System in Ethiopia:
           Its Implications for Food Security

    • Abstract: Food security is a key issue worldwide and must be considered in both spatial and temporal contexts. Securing the availability of food somewhere in a country does not ensure food security in other areas. Similarly, securing food available today does not guarantee its availability tomorrow. Therefore, parameters such as rapid population growth, urbanization, changing consumption patterns, and globalization, as well as climate change and depletion of natural resources, must be kept in mind while planning the issue of food security. In this regard, Enset, which is a large perennial herbaceous crop native to Ethiopia, is highly stapled to approximately 20 million people in the southern, eastern, and central parts of Ethiopia. It is a common practice in the agricultural system of these areas, making these areas Enset belt regions of the country. On the other hand, the remaining parts of the country often do not practice such farming systems despite the fact that there are good opportunities to do so. One way of expanding the experience of Enset culture is through promoting its food system and multiple-use dynamics. Hence, decision-makers and policy designers in the area of agriculture would consider intensifying Enset to its nonbelt areas, to transform agricultural and food systems to end hunger, achieve food security, and improve nutrition.

  • Reducing Postharvest Loss of Stored Grains Using Plant-Based
           Biopesticides: A Review of Past Research Efforts

    • Abstract: The world population is projected to be 9.1 billion by the year 2050, and about 70% extra food will be required. One of the main challenges regarding food security is postharvest loss due to insect pests. The overall postharvest grain losses for sub-Saharan Africa could be as high as US$4 billion/year. This is around 15% of the total production of cereal crops. The use of chemical pesticides to reduce grain damage by insects over the past five decades has led to a range of environmental and human health problems. These problems forced researchers to develop alternative methods that have lower adverse effects. Alternative strategies focus on new forms of pesticides that are effective against a specific target species, have fewer residues in food, are unlikely to contaminate the environment, and have lower potential to produce resistance, are biodegradable, and are suitable for use in integrated pest management programs. Some natural plant products effectively meet these criteria and have the potential to manage insect pests of stored grains. However, the understanding of the use of botanical pesticides in storage pest management systems is limited in most parts of sub-Saharan African countries. Effective plant products are not formulated and used widely. To fill the gaps the first step is to synthesize the available information and disseminate it. This review is, therefore, a summary of the current developments and improvements of botanical pesticides in the management of stored grain pests including challenges and future issues in insect pest management.

  • Opportunities and Challenges for Pastoral Beef Cattle Production in

    • Abstract: The beef cattle production sector plays a crucial role in the livelihoods of pastoral farmers in Ethiopia, and it is the main source of beef animals for domestic and foreign markets. As compared to other African countries, Ethiopia has a huge beef cattle population (65.35 million heads). However, the quality and quantity of beef, as well as per capita meat consumption of Ethiopians, are very low (8.4 kg/individual/year). In this sense, the goal of this review was to provide and synthesize the most validated scientific information on the opportunities and challenges for pastoral beef cattle production in Ethiopia. The potential for pastoral beef cattle producers in Ethiopia included population growth, urbanization, literacy, and family income, as well as high demand for beef animals in domestic and foreign markets. In contrast, problems with beef cattle production systems, diseases, shortages of feed and water, lack of veterinary services, droughts, lack of market access and infrastructure, illegal animal trades, and poor genetic potential of indigenous cattle are among the limiting factors that hamper efficient beef production in the country. In Ethiopia, the yield and compositional quality of beef are very low compared to other African countries and the global market in general. Therefore, empowering pastoral beef cattle producers will help us to supply high quality and quantity of beef and will ensure sustainable beef cattle production with an identified market destination and access.

  • Evaluation of Grain/Seed Yield and Yield Components of Finger Millet and
           Three Vetch Species Intercropped at Various Seeding Ratios at Bako,

    • Abstract: Production of finger millet and vetch species in Ethiopia targets mostly on sole cropping system without considering the relative performance of varieties of varying seeding ratios under finger millet/vetch intercropping. Thus, this study was conducted to evaluate grain yield and yield components of three vetch species and finger millet intercropped at different seeding ratios. Factorial combination of three vetch species and five seeding ratios (0 : 100, 25 : 75, 50 : 50, 75 : 25, and 100 : 0% finger millet: vetch) were laid out in a randomized complete block design (RCBD) with three replications. Analysis of variance showed that intercropping had a significant () effect on plant height, heads per plant, fingers per head, and grain yield of finger millet. The highest grain yield (2058.75 kg ha−1) of finger millet was harvested from a treatment combination of 75% finger millet + 25% Vicia villosa. Analysis of variance also showed that plant height, leaves per plant, branches per plant, pods per plant, seeds per pod, and seed yield of vetch species had significantly varied () for the tested treatments. Maximum and minimum seed yields (236.19 and 106.45 kg ha−1) of vetch were harvested from 25% finger millet + 75% Vicia sativa and 75% finger millet + 25% Vicia villosa, respectively. LER and RCC were improved due to intercropping different species of vetch with finger millet at various seeding ratios. The highest total LER (1.146) and RCC (3.00) were obtained from 75% finger millet + 25% Vicia villosa. Thus, it can be concluded that in Bako and similar agroecologies, where feed shortage is a critical problem, intercropping of 75% finger millet + 25% Vicia villosa can be used to alleviate the existing feed shortage in smallholder farming system.

  • Youth Participation in Agricultural Enterprises as Rural Job Creation Work
           and Its Determinants in Southern Ethiopia

    • Abstract: Even though agriculture has ample potential to absorb a large number of people, youths tend to stand away from the subsector. As a result, rural job creation works were started in southern Ethiopia by participating youth in different agricultural enterprises in the form of groups and cooperatives. However, as compared to sector potential, youths are not participating in agricultural job creation works in Ethiopia. Therefore, this study was intended to assess factors affecting youth participation in agricultural enterprises in selected districts of Southern Ethiopia. A multistage sampling procedure was followed to select 160 sample youths. The collected data from sampled youths were analyzed by both descriptive statistics and a probit econometric model. Among the agricultural enterprises, the majority of the youths (63.3%) preferred livestock enterprises indicating livestock sector job creation capacity in Ethiopia. The seasonal nature of agricultural income, fear of agricultural risk, and lack of initial capital were the top three factors hindering youth participation in the agricultural enterprise as rural job creation works. The probit model result shows that, among the hypothesized variables, education level, credit getting bureaucracy, lack of initial capital, fear of the group, risk and uncertainty, and lack of working place determine significantly youth participation in agriculture enterprises. Hence, respective bodies must group youths based on their preferred interest and evaluate their business plan critical before credit disbursement, while solving credit providing terms problems on the microfinance side and the introduction of agricultural insurance through these youth agricultural enterprises for agricultural risk fear needs stakeholders’ interventions. Overall, initial savings, interest rate, and payback period of credit need special policy adjustments to increase youth participation in an agricultural enterprise.

  • Evaluation of the Plant Growth Promotion Effect of Bacillus Species on
           Different Varieties of Tomato (Solanum lycopersicum L.) Seedlings

    • Abstract: Tomato is the most widely eaten vegetable and used as a good source of vitamins A, B, C, and D and minerals such as calcium, phosphorus, and iron. The study was done to evaluate the effect of Bacillus species isolated from the sediment of Lake Tana on the early growth of different tomato (Solanum lycopersicum L.) varieties. All Bacillus isolates significantly () increased the growth of all three tomato varieties in terms of shoot length, shoot fresh weight, shoot dry weight, root length, and fresh and dry weights of the root. The isolates’ efficacy varied among tomato varieties. Bacillus isolate B2 was more effective in the Maya variety, with a potency of 85% and 71.2% shoot and root lengths, respectively. Bacillus isolate B3 was more efficient in the Melkesalsa variety, with a shoot and root length efficiency of 57% and 68%, respectively. Bacillus isolate B1 was more successful in the Kochero variety with 65 and 70% shoot and root length efficacy. Individual isolates’ PGPR characteristics differed, resulting in a wide range of effectiveness among different varieties. More research studies are needed to fully know the mechanism of action and efficacy of these isolates in the field. The isolates must also be identified using molecular techniques.

  • Genetic Transformability of Selected Kenyan Groundnut (Arachis hypogaea
           L.) Genotypes with IPT Gene Using Cotyledonary Node Explants

    • Abstract: Groundnut (Arachis hypogaea L.) is an important crop in terms of income and nutrition. Despite its importance, groundnut yield is limited by environmental factors such as drought. This work reports the genetic transformability of Kenyan groundnut (Arachis hypogaea L.) genotypes with isopentenyl transferase (IPT) gene towards drought tolerance. The cotyledonary nodes of six Kenyan adapted groundnuts genotypes (ICGV 12991, CG 7, Red Valencia, ICGV 90704, Chalimbana, and JL 24) were transformed using Agrobacterium tumefaciens strain EHA 101 carrying PNOV-IPT binary vector containing an IPT gene, which was driven by SARK promoter and terminated by TNOS terminator. The vector also contained the phosphomannose isomerase (PMI) gene for the selection of transformed tissues. Putative transformants were tested for the presence of the transgene by PCR designed to amplify the IPT gene sequence. Gene expression was confirmed by RT-PCR. Transformation frequency was calculated as a percentage of the number of putative transformants divided by the total number of infected cotyledonary nodes. This ranged from 9.87% for ICGV 90704 to 19.77% for JL 24. Transformation efficiency was calculated as a percentage of the number of PCR positive plants divided by the total number of cotyledonary nodes infected. This ranged from 0% for ICGV 12991 and Chalimbana to 1.74% for JL 24. The data suggest the possibility of transforming groundnuts with the IPT gene and regenerating normal transgenic plants. This information will be useful during the transformation of groundnut towards different factors that affect production.
