  • Biopesticides: a sustainable approach for pest management

    • Authors: Sovit Parajuli, Jiban Shrestha, Sudeep Subedi, Meena Pandey
      Pages: 1 - 13
      Abstract: Biopesticides are an important component of Integrated Pest Management (IPM) programs for insect pest control since they are more natural, environmentally friendly, safer than chemical pesticides and have relatively no or little effect on non-target organisms. They aid in improving crop health and yields while lowering production costs and eliminating the usage of toxic chemicals. They are effective tools for creating new sustainable agricultural products. Several botanicals and microbial biopesticides have been identified, isolated, processed, and used to eliminate hazards caused by Coleopteran, Hemipteran, Dipteran, Lepidopteran, Hymenopteran, and Thysanopteran insects. Several species of botanicals such as Neem (Azadirachta indica A.), Chili pepper (Capsicum annuum), Garlic (Allium sativum), Moringa (Moringa oleifera), Clove basil (Ocimum gratissimum), China berry (Melia azedarach), bitter leaf (Vernonia amygdalina) etc. and microbes such as Bacillus thuringiensis, Beauveria bassiana, Metarhizium anisopliae, Baculovirus (nucleopolyhedrovirus (NPV) and granulovirus (GV) ), Steinernema carpocapsae, Nosema, etc. have been used as biopesticides. Because biopesticides are successful in managing insect pests and diseases while also being safe to humans and the environment, they must be manufactured in the country and made available to farmers.

  • Genetic divergence of guava (Psidium guajava L.) genotypes in Bangladesh

    • Authors: Haimonti Barua, Satya Ranjan Saha, Nasrin Akter Ivy , Golam Rasul, AKM Aminul Islam
      Pages: 15 - 28
      Abstract: A noticeable variation is present among the guava (Psidium guajava L.) genotypes available in Bangladesh. Thirty-three (25 indigenous, 5 released, and 3 exotic) genotypes of guava were used in ex-situ conditions from different locations of Chattagram, Brahmanbaria, Pirojpur, and Gazipur districts and assessed based on 10 traits to know their genetic diversity. The measured traits were number of flowers, fruits, harvested fruits per plant, single fruit weight (g), number of seeds/fruits, thousand seed weight (g), vitamin C, total sugar content, and fruit yield/plant (kg). Twenty-one genotypes showed 100-400 g of single fruit weight, and 12 showed 20-100 g. The genotype G14 (BARI Peyara-1) produced the highest fruit yield/plant (131.04 kg) followed by G24 (PG Muk-005) and G 23 (PG Muk-005) yielded 65.49 kg and 64.62 kg, respectively. Twenty-one genotypes showed above 250 mg/100g vitamin C content. Above 42% (14 genotypes) contained total sugar content of over 5%. The first two axes accounted 58.8% of the total variation among 10 traits. Based on the heatmap analysis, cluster-IV represents a high value containing the number of flowers, fruits, and harvested fruits per plant. The genotypes G 14, G17 (BARI Peyara-4), G21 (PG Sit-003), G23, G24, and G29 (Thai Peyara-3) might be considered the best based on the morpho-biochemical characteristics. Many traits are of significant economic importance and could be used as breeding targets to increase yield and quality. Therefore, variation among guava genotypes will be an excellent source for future crop improvements. SAARC J. Agric., 20(1): 15-28 (2022)

  • Evaluation of genetic variation in segregating population of pea (Pisum
           sativum L.)

    • Authors: S Tasnim, Nasrin Akter Ivy, Mohammad Sharif Raihan, Nadia Akter, MZ Islam, N Jahan, Ahasan Ullah Khan
      Pages: 29 - 39
      Abstract: Pea (Pisum sativum L.) is the most important grain legume crop grown worldwide and used as food and fodder. An experiment was undertaken to elucidate the genetic variability in five inbred parents and their 17 F4’s derivatives in pea evaluating ten characters during the winter season of 2017-2018 at the research farm, BSMRAU, Gazipur, Bangladesh. Analysis of variance explored significant differences among the genotypes for all the characters. Phenotypic coefficients of variation were close to genotypic coefficients of variation for all the characters indicating less influence on the environment and potentiality of selection. High heritability associated with high genetic advance was observed for plant height, pod per plant, hundred seed weight, and seed yield per plot. Days to 50% flowering and days to first flowering showed a highly significant positive correlation at both genotypic and phenotypic levels. Plant height showed a highly significant positive correlation with pods per plant, seeds per pod, and seed yield per plant. Pod length showed a highly significant positive correlation with pod width and hundred seeds weight. Pods per plant, pod width, and seeds per pod showed a highly positive correlation with seed yield per plant and 100-seed weight. Only days to first flowering showed a highly negative correlation with pod length and hundred seed weight. Path coefficient analysis revealed that plant height, pod per plant, and seeds per pod had a highly positive effect on yield per plant. Therefore, the yield improvement of pea is plausibly possible by associating and selecting those plant traits. Furthermore, two crosses such as Zhikargacha×IPSA Motorshuti 1 and Zhikargacha×IPSA Motorshuti 2 may be chosen for further breeding programs. SAARC J. Agric., 20(1): 29-39 (2022)

  • Biochemical and molecular characterization of some advanced mutant rice
           (Oryza sativa L.) Genotypes

    • Authors: Md Kawsar Alam Nadim, Mariom Mitu, Md Monirul Islam, Md Shamiul Haque, SM Abdul Alim, Sayed Eshtiak Akter, Md Golam Mortuza, Kamal Uddin Ahmed
      Pages: 41 - 53
      Abstract: Rice (Oryza sativa L.) is one of the main cereal crops in the world and the main staple food of Bangladesh. Amylose content of rice endosperm is the main chemical properties that contributes the eating and cooking quality. On the other hand, rice protein is the important source of nutrition of almost 50 per cent of the world’s population living on rice. A total of 12 rice genotypes including ten advanced mutant lines, one landrace namely Laxmidigha along with BRRI dhan49 was collected from Plant Breeding Division of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh and Bangladesh Rice Research Institute (BRRI), Gazipur. The genotypes were analyzed to assess the amylose and protein content as well as their genetic diversity relationship. Among all the tested genotypes amylose content were ranged from 23.9-20.3% where highest amylose percentage was found for Magic-86 (25.6%). Protein content of the genotypes were ranged from 8.50-5.04%, where highest 8.86% protein was recorded for SSB-3. The highest gene diversity (0.81) was observed in RM519 marker and the lowest (0.28) was in RM111 marker. The PIC values ranged from 0.24-0.78 with a mean of 0.51. The highest Nei’s genetic distance value 0.87 was found in RM-16(N)-10 vs RM-40(C)-4-2-8 and the lowest value 0.18 was found in LD-200-1-3-3-8 vs LD-200-1-3-2-4. A dendogram was constructed using UPGMA system based on Nei’s similarity coefficient and six major clusters were obtained at 0.7 cut off. The genotypes showing diverse ranges of amylose and protein content tended to cluster together in the dendogram with some exceptions. SAARC J. Agric., 20(1): 41-53 (2022)

  • Effect of different concentrations of pyrethroid and organophosphorus
           pesticides on seedling growth of Cicer arietinum

    • Authors: Renu Dixit, Manju Rani, Jitendra Kumar
      Pages: 55 - 65
      Abstract: Seed treatment with pesticides is one of the components of IPM. Pesticides, the chemical ingredients are generally used to assassinate biological entities that cause damage to cultivated crops. To maintain the quantity and quality of the plant produce, a large number of chemicals in the form of pesticides and/or fungicides are sprayed on them. Although these compounds affect the growth of seedlings and also negatively influence the growth of symbiotic bacteria and their interaction with crop plants resulting in a reduction in nitrogen fixation by plants and ultimately yield. A study on the consequences of chemical pesticides on seed germination and seedling growth of Cicer arietinum was carried out at Chhatrapati Shahu Ji Maharaj University, Kanpur, Uttar Pradesh, India in 2016. The present study was done to assess the effect of pesticides on root length, shoot length, leaf area, fresh weight, and dry weight of seedlings. The experiment was conducted by using different concentrations viz., 0% (control), 0.5%, 1%, 1.5%, 2%, 2.5%, 5%, 7.5%, and 10% of organophosphorus monocrotophos and pyrethroid pesticide deltamethrin. Observations were done on the 7th, 14th, and 21st days of radicle emergence. The study showed that both types of pesticides such as pyrethroid deltamethrin and organophosphorus monocrotophos were found to be toxic to plants in high concentrations and can be preferred in low concentrations only like 0.5%, which is less harmful to crop plants.

  • Comparative study of selected tossa jute varieties (Corchorus olitorius)
           in response to the presence of fungi

    • Authors: Fakhar Uddin Talukder, Md Sohanur Rahman, Md Mia Mukul, SMA Haque
      Pages: 67 - 76
      Abstract: The purpose of this study was to observe the germination rate and fungal pathogens association in selected Tossa jute varieties. The experiment was conducted following Completely Randomized Design (CRD) with four replications. Truthfully labelled seeds (TLS) collected from four districts in Bangladesh, was used in the present study. The Highest germination rate (93.5%) and the lowest infection (31.25 pathogens/100 seed) were observed in BJRI Tossa Pat 5 (O-795) variety. BJRI Tossa Pat 4 (O-72) was observed as the most vulnerable against pathogen infection (121.25 pathogens/100 seed) and the showed lowest germination (83.25%). Regressions co-efficient (β) -0.82 was observed between germination (%) and total number of pathogens on seeds. Regression co-efficient (β) was -0.71 between moisture (%) and germination (%) of Tossa seeds. Regression co-efficient (β) was 0.65 between moisture (%) and total number of pathogens at Tossa jute seeds. For conducting the experiment, there was no limitation. From the study, it may be concluded that, seed-borne pathogenic fungi negatively affect the germination (%) of Tossa jute seed. SAARC J. Agric., 20(1): 67-76 (2022)

  • Life cycle and morphometrics of fall armyworm (Spodoptera frugiperda)
           (Lepidoptera: noctuidae) on maize crop

    • Authors: Sheela Sharma, Sundar Tiwari, Resham B Thapa, Saraswoti Neupane, Gadi VP Reddy, Suroj Pokhrel, R Muniappan
      Pages: 77 - 86
      Abstract: Fall armyworm (FAW) (Spodoptera frugiperda J.E. Smith) is a polyphagous pest, native to North and South America and is invasive in Eurasia and Africa. Life cycle and morphometric studies with the invasive population of FAW in Nepal were conducted under laboratory conditions in Chitwan, Nepal. Gravid females laid an average of 156.25 eggs per egg batch, with an average of 979.43 eggs during their whole lifetime. The average pre-oviposition period was 3.75 days, oviposition period was 3 days, the larval developmental period was 16.31 days, the pupal period was 9.69 days, and the whole life cycle (egg to egg) averaged 33 days. The average length of each instar larva from I to VI instars was 1.5, 3.6, 7.1, 11.6, 18.5, and 34.4 mm, respectively. Head capsule widths for each instar were 0.35, 0.47, 0.8, 1.37, 2.11, and 2.7 mm, respectively for instars first through sixth. Pupal and adult emergence rates were 98.9 and 97.2%, respectively, with a male to female ratio of 1:1.3. Larval mortalities of the I, II, and III instars were 70, 66, and 12%, with no mortality in the IV, V and VI instars. Adult longevity was 20.73 days for males and 22.78 days for females. These findings are useful to design an integrated management protocol of the fall armyworm. SAARC J. Agric., 20(1): 77-86 (2022)

  • Defoliation impacts on morpho-physiological attributes and yield of tomato

    • Authors: M Monjurul Alam Mondal
      Pages: 87 - 96
      Abstract: The experiment was conducted under sub-tropical condition during two successive seasons (November-March) of 2017-18 and 2018-19 to investigate the effect of defoliations on morpho- physiological attributes and yield of tomato. The experiment comprised of five levels of defoliation viz., 0 (control), 3, 6, 9 and 12 leaves defoliation from the base out of 17 leaves at the beginning of flowering stage and two widely cultivated varieties viz., TM-110 and TM-135. The plant characters such as leaf area, plant height, number of leaves plant-1, straw weight plant-1, absolute growth rate, number of fruits plant-1, individual fruit weight and fruit yield were not affected up to 6 leaves defoliation irrespective of seasons and genotypes. Interestingly, photosynthesis, nitrate reductase and reproductive efficiency increased with increasing defoliation levels. Morpho-physiological parameters and yield attributes were better in 3 and 6 leaves defoliated plants over the control with being the highest in 6 leaves defoliated plant, which resulting the highest fruit yield. Heavy defoliation not only reduced source sizes but also decreased total sink (fruits) causing lower fruit yields. The lowest morpho-physiological attributes and fruit yield was recorded in 12 leaves defoliated plants. These results indicate that tomato plants can tolerate one-third leaf loss during reproductive stage and the knowledge of which might be essential for maintaining better quality tompato production.

      Abstract: Experiment was conducted at the Agricultural Farm of Patuakhali Science and Technology University to know the morphological characteristics of different mutants of mungbean and to find out tolerant/least susceptible mutant(s) against flea beetle, aphid and pod borer based on the reaction of insect pests to promising mutants of mungbean during the period from April to June, 2015. The mutant MBM-07(S)-2 was found to be the tallest (32.57 cm) with highest number of branches/plant (5.03), highest number of leaves/plant (11.06) among all mutants and check variety while MBM-07-Y-2 (23.40 cm) was the shortest plant height, MBM-656-51-2 had the lowest number of branches/plant (3.73), MBM-347-13 (7.03) had the lowest number of leaves/plant. The mutant MBM-427-87-3 had the highest number of pods (5.00) compared to other mutants but MBM-656-51-2 had the lowest number of pods/plant (3.09). Significantly the highest pod length and the highest number of seeds/pod were recorded in the mutant MBM-07-Y-1 (6.37 cm) while the lowest pod length (5.19 cm) was in MBM-80(LCAL) and lowest number of seeds/pod was in the mutant MBM-390-94-Y (5.34). Mutant MBM-347-13 had the lowest population of flea beetle (18.00) and pod borer (2.00) compared to all other mutants while the lowest number of aphid/plant was observed in mutant MBM-07-Y-1 (1.00). In case of infestation, the mutant MBM-347-13 had the lowest percentage of infestation (20.69%) by flea beetle, (3.18%) by pod borer but the lowest infestation by aphid (3.33%) was recorded in the mutant MBM-390-94-Y while the mutant MBM-427-87-3 had the highest percentage of plant infestation (37.80%) by flea beetle, pod damage (9.69%) by pod borer and variety BARI moog-6 had the highest percentage (34.45%) of plant infestation by aphid. Mutant MBM-347-13 was least susceptible to flea beetle and pod borer while mutant MBM-427-87-3 was highly susceptible to flea beetle and pod borer. However, mutant MBM-390-94-Yand MBM-07-Y-2 were less susceptible to aphid while BARI moog-6 and mutant MBM-427-87-3 were highly susceptible to aphid. SAARC J. Agric., 20(1): 97-106 (2022)

  • Polyethylene glycol mediated drought stress impacts on germination, growth
           and accumulation of proline in rice (Oryza sativa L.)

    • Authors: Muhammad Abdus Sobahan, Nasima Akter, Md Masud Rana
      Pages: 107 - 119
      Abstract: Drought is one of the major stress factors affecting the growth and development of plants, and is responsible for considerable crop yield losses worldwide. An experiment was conducted to compare three rice (Oryza sativa L.) varieties (BRRI dhan49, BRRI dhan71 and BRRI dhan75) for drought tolerance based on some growth parameters and physiological status in germination stage. Drought stress was imposed by five levels of polyethylene glycol (PEG) (0%, 10%, 15%, 20% and 25%). Rice varieties showed good germination with PEG concentration up to 15%. At 20% PEG concentration, a sharp reduction in germination percentage was observed and the highest germination percentage (55.53%) was found in the variety BRRI dhan71. Seeds of all the varieties treated with 25% PEG did not germinate. Seedling growth in terms of plumule and radicle length, fresh weight and dry weight decreased with increasing drought stress in all the varieties. Among the varieties, BRRI dhan71 was found to be the best at 20% PEG for seedling growth. Drought stress treatments decreased seedling length and weight vigor index in rice, whereas the highest seedling length and weight vigor index were obtained from BRRI dhan71. Accumulation of proline increased along with the increase of PEG concentration. The highest proline accumulation (3.08 mmol g-1 leaf) was obtained from the BRRI dhan71 at the higher treatment (20% PEG). This result suggests that BRRI dhan71 showed best performance under drought stress because of its own nature of tolerance. SAARC J. Agric., 20(1): 107-119 (2022)

  • The relationship between heavy metals concentrations in soil and plant
           (Senna auriculata (L.) Roxb.) of the hills and roadsides in
           Tiruchirappalli, India

    • Authors: SP Anand Anand, Nagalakshmi Ramamoorthy

      Abstract: The relationship between heavy metal concentrations of soil and plant (Senna auriculata) in the hills and roadsides was studied. Atomic absorption spectroscopy was used for determination of metals such as lead (Pb), chromium (Cr), cadmium (Cd), zinc (Zn), copper (Cu), and iron (Fe) in the soil and plant (leaves and flowers) samples. The results showed that heavy metal concentrations in roadside soil and plant samples were much greater than that in hills. It is evident that concentration of a heavy metal in soil samples are considerably higher (p<0.05) than that in plant samples. Pearson correlation analysis shows that Pb in leaves and flowers correlated well with that in soil, r >0.93. Strong positive relationship exists between soil and plant for Cr content, (r≥0.97). Cadmium and Zn contents in leaves and flowers correlated significantly with Cd, and Zn in soil, all r>0.97. The Cu concentration of leaves and flowers shows a positive correlation with Cu content in soil, all r≥0.93. The Fe concentration of both plant leaves and flowers is found significantly and positively correlated with soil Fe, r=0.99. Overall results reveal that all the heavy metals are significantly and positively associated with soil and plant, implying that increasing concentration of heavy metals in soil is likely to increase their concentrations in S. auriculata plant.

           Lalmai-hill area

    • Authors: Md Nayeb Ali Khan, Md Babu Hossain, Parimal Kanti Biswas, AKM Ruhul Amin, Anisur Rahman
      Pages: 143 - 155
      Abstract: A field experiment was conducted in Lalmai-Hill area of Cumilla with five high yielding varieties (HYV) of rice during Boro season (2018-2019) to evaluate their yield performance under different transplanting dates. Rice seedlings were transplanted on three different dates viz., January 15 (T1), January 30 (T2) and February 14 (T3). Five rice varieties viz., BRRI dhan67 (V1) BRRI dhan68 (V2), BRRI dhan74 (V3), BRRI dhan81 (V4) and BRRI dhan86 (V5) were transplanted. Results revealed that delaying of transplanting date decreased yield and return of Boro rice varieties. Transplanting of seedlings on February 14 decreased effective tiller hill–1, filled grain panicle–1, grain yield and biological yield by 13, 14, 24 and 9%, respectively, compared to seedlings transplanted on January 15. Significantly highest grain yield (5.95 t ha–1) and biological yield (14.33 t ha–1) were obtained from BRRI dhan74 compared with other varieties because of higher potential of its yield attributes. The highest grain yield (6.67 t ha–1) and return (Tk. 158,765 ha–1) were recorded from BRRI dhan74 when transplanted on January 15 as compared to other combinations. Transplanting of all other varieties on January 15 confirmed higher yield and yield return compared with delayed transplanted seedlings. SAARC J. Agric., 20(1): 143-155 (2022)

  • Effect of post-shooting bunch spray of growth hormone and fertilizer on
           yield attributing characters of banana

    • Authors: Nitesh Wagle, Shaurav Sharma, Keshav Bhattarai, Deepak Khatri, Jay Prakash Dutta
      Pages: 157 - 169
      Abstract: An experiment was conducted at a commercial banana orchard in Chitwan to find out the best chemical to increase the yield and quality of banana during the fruit development stage. The research was laid out in a randomized complete block design (RCBD) with seven treatments and three replications. The treatment included plant growth hormones GA3 and Naphthalene acetic acid (NAA)@ 50 ppm and 100 ppm each. Similarly, Sulphate of Potash (SOP) was applied @ 1.5% and 2%. The first spray was applied soon after the bunch had completely opened, and the second spray was applied 15 days later. The effect of these chemicals on yield and quality parameters was observed. The result revealed that the application of GA3 @ 100 ppm increased the length, girth and weight of the bananas. Likewise, the highest weight of the third hand of the banana was also observed in GA3 @ 100 ppm, whereas minimum physiological loss in the weight of the finger and maximum pulp to peel ratio was observed in SOP @ 1.5%. Analyzing all these observed parameters, GA3 @ 100ppm was found to be the most suitable growth hormone to increase the overall yield while SOP @ 1.5% SAARC J. Agric., 20(1): 157-169 (2022)

      Abstract: Pesticide application against insect pest infestation is environmentally unsafe and costly. An attempt was taken to evaluate the solar light trap as ecofriendly and cost-effective approach in Transplanted Aman rice (BRRI dhan32) field at Barhatta Upazila (Sub-district) in Netrokona district of Bangladesh. It was found that rice pest like Rice yellow stem borer, Rice leaf roller, Green leaf hopper, Brown plant hopper, Rice leaf miner, Rice gall midge, White leafhopper, Rice bug, Rice ear cutting caterpillar, White-backed planthopper, Rice caseworm, Grasshopper, Rice skipper and Rice beetle were the major insects that captured under the solar light traps. Some beneficial insects were also attracted by the trap these were Ladybird beetle, Water scavenger, Giant water bug, Ground beetle, Rove beetle, Damsel fly. All the harmful and the beneficial insects were belonging the order of Lepidoptera, Hemiptera, Orthoptera, Coleoptera, Diptera and Odonata. Though the mean yield of rice was statistically insignificant in both fields, the light trap installed fields required the less frequency of pesticides than the control fields which ultimately rendered the low pesticides cost in a great extent. On an average 1,034 BDT was reduced in per hectare. SAARC J. Agric., 20(1): 171-183 (2022)

  • Formulation of value added chicken nuggets using carrot and ginger as a
           source of dietary fiber and natural antioxidant

    • Authors: MM Khatun, MA Hossain, MS Ali Ali, MM Rahman, MAK Azad , MA Hashem
      Pages: 185 - 196
      Abstract: The study was aimed to evaluate the effect of different levels of carrot with ginger on the quality attributes of chicken nuggets. For this purpose, chicken meat samples were divided into four treatment groups viz. T0 (Control), T1 (1% ginger and 4% carrot), T2 (1% ginger and 8% carrot) and T3 (1% ginger and 12% carrot). Days of intervals were 0, 15, 30 and 45th days. Samples were preserved at -20º C for 45 days. An ANOVA of a 4×4 factorial experiment in completely randomized design having three replications per treatment was used for analyses of data. Sensory, proximate, physicochemical, biochemical and microbiological analyses were determined. Color, flavor, juiciness, tenderness and overall acceptability increased significantly (p<0.05) among the different treatment groups but decreased at different days of intervals. Dry matter (DM) content decreased significantly (p<0.05) with different treatment levels and increased with days of intervals. Crude protein (CP), Ether extract (EE) and ash content of all treatments were decreased significantly (p<0.05) among different treatment groups. Free fatty acids (FFAs), peroxide value (POV) and thiobarbituric acid reactive substances (TBARS) values were decreased significantly (p<0.05) with different treatment levels and increased with days of intervals. Total viable count (TVC), total coliform count (TCC) and total yeast mold count (TYMC) decreased significantly (p<0.05) at different treatments. On the basis of sensory, physicochemical, biochemical and microbial properties indicate that T3 was the best among treatment groups. Hence, 12% carrots with 1% ginger extracts may be recommended for formulation of value added chicken nuggets as enriched dietary fiber and natural antioxidant. SAARC J. Agric., 20(1): 185-196 (2022)

  • Technical Efficiency in Potato Cultivation in Brahmaputra Valley of Assam,
           India

    • Authors: Rimjim Bordoloi, Ashi Lama
      Pages: 197 - 208
      Abstract: Potato is abundantly grown in Assam and is an important source of income and employment in rural areas of the state. But the productivity of potato in the state is low as compared to other states. Among the various factors, productivity of a crop is significantly influenced by technical efficiency. This paper examines productivity and technical efficiency in potato cultivation in Brahmaputra Valley of Assam, India. The study is based on both secondary and primary data. Primary data were collected from a sample of 400 potato growers. The study applied stochastic frontier production function to estimate technical efficiency and employed logistic transformation model of regression analysis to examine the determinants of technical efficiency. The results showed that potato productivity was positively and significantly affected by seed, fertilizer and manure costs. The mean level of technical efficiency among the farmers was 78%. Technical efficiency was found to be the highest in semi-medium and large land holdings. Technical efficiency was positively affected by land size and negatively affected by capital-labour ratio. The study implies that there is a need to promote use of quality seeds and plant nutrients to improve productivity and encourage extensive farming and use of labour to enhance technical efficiency in potato cultivation.

      Pages: 209 - 225
      Abstract: Livestock is a vital component of the complex farming system in Bangladesh. This focuses towards he contribution of livestock farming in the livelihood of the farmers as well as the realization of the challenges in livestock farming as perceived by the farmers. A mixed-method research design was used to collect data from 100 livestock farmers of Kamarkhanda Upazila (sub-district) under Sirajganj district. According to the findings of the study, livestock farming has significant contributions in improving the status of livelihood tatus of farming households. It is evident from the findings that majority of the respondents (69%), faced medium level of challenges in livestock farming compared to high level of challenges faced by 28% respondents of the study area. The socio-demographic characteristics of the respondents namely farm size, annual income, training received, subsidy received and extension media contact seem to have significant contributions with the challenges faced by the farmers in livestock farming. As the livestock sector of Bangladesh has great potential to flourish provided the challenges faced by the farmers are given due attention. Implementation of farmers’ friendly livestock policy and the collaborative efforts of public and private sectors are required to boost up livestock productivity in Bangladesh. SAARC J.

  • Assessing Mango Fruit Value Chain in Bangladesh

    • Authors: Ranjan Roy, Md Anisur Rahman
      Pages: 227 - 238
      Abstract: Addressing the systemic constraints is very important for the economics of mango production in Bangladesh, which is the 7th largest mango producing country in the world. Based on the functions any value chain includes three function actors and different dimensions such as inclusiveness (i.e., extreme poor inclusion) and gross margin, the study qualitatively and quantitatively assessed mango fruit value chain. Methodologies were applied with an assemblage of bottom-up and top-down approaches. Structured questionnaires were used to survey mango producing households, input sellers and mango buyers. The percentile value of composite revealed that mango fruit production and selling the annual specified gross margin (SGM) were Tk.1,600 (66%) for extreme poor (hereafter referred to as EP) producers, while Tk.1,09,880 (64%) for rich producers and Tk. 2,43,000 (76%) for retailers/middleman. The profit margin of medium and rich producers as well as middlemen was better, but less for poor and EP households due to the systemic market constraints. This assessment aims to prepare improving strategies and/or interventions for mango production that elucidates what actions could be taken for the mango fruit value chain in different segments such as improved technologies, harvesting, grading, packaging, transportation, marketing, etc. so that the poor and EP households will get more profit margin from mango production.

  • Determinants of production and marketing of vegetables in kailali district
           of Nepal

    • Authors: Santoshi Malla, Sagar Malla, Sagar Bhandari, Hema Joshi, Jiban Shrestha
      Pages: 239 - 252
      Abstract: The objective of this study was to find out the existing vegetable production and marketing practices in the Kailali district of Nepal. A total of 100 vegetable growers were selected using a simple random sampling technique. Data collection was done by using a semi-structured interview. Secondary data was collected from the reports and journal articles. Indexing techniques and descriptive statistics were used in this study. It was estimated that the average size of a household's landholding was 0.1689-0.337 hectares. Forty-eight percent of the households earned NRs 1,00,001–2,00,001/year from vegetable farming. About 93% of the farmers were interested in off-season vegetable production. Around 45% of households used different fertilizers, namely urea, DAP, and MOP. Insect and disease attacks (index value = 0.82) were the major problems. Aphid (index value = 0.818) and blight (index value = 0.768) were reported as the major pest and disease, respectively. About 47% of farmers grew hybrid seeds. Farmers sold their products in India (50%), Dadeldhura (30%), and local markets (20%).The management of insect pests and diseases, access to chemical fertilizers and hybrid seeds, and the provision of offseason vegetable production training to farmers are necessary for the promotion of commercial vegetable production in the district.
