  • Laboratory Studies of Larval Cannibalism in Same-age Conspecifics of Fall
           Armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera, Noctuidea) in

    • Abstract: Fall Armyworm (Spodoptera frugiperda) (FAW) is an economically important pest worldwide and larval cannibalism is documented as one of its significant behaviors under field and laboratory conditions. The incidence of larval cannibalism amongst same-age larvae of Fall Armyworm was investigated under laboratory conditions using 73 laboratory trials with not less than five trials for each instar stage. Each instar stage was provided with their conspecifics along with sufficient food. Direct observations were carried out in 24 hour time laps to record the missing larvae which were presumed as cannibalized. The mean cannibalism proportion was calculated for each larval stage. All larval stages except the first and second instar stages displayed same-age conspecific cannibalism. An increasing trend of the mean cannibalism proportion was observed from the third (0.16±0.04) to the fifth instar stage (0.22±0.05) with the highest value recorded for the fifth larval instars. The trend dropped at the sixth instar stage. The study suggests that larval cannibalism is evident amongst same-age larval instars of Spodoptera frugiperda, which may affect ecological relationships between organisms of a system.

  • Morpho-Physiological and Genetic Characterization of Transplanted Aman
           Rice Varieties Under Old Brahmaputra Flood Plain (Aez-9) in Bangladesh

    • Abstract: Rice is a staple food in terms of acreage and production in Bangladesh. The assessment of genetic variability in rice genotypes is essential to identify suitable characters for its further improvement. An experiment was carried out to study the morpho-physiological and genetic characteristics of transplanted Aman (one of the important rice growing seasons in Bangladesh) rice cultivars. Ten Aman rice varieties were tested as treatments and the experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The analysis of morpho-physiological traits in tested rice varieties demonstrated that the higher number of effective tillers per hill, panicle length, grains per panicle and 1000 grain weight was the most yield contributing traits those were influenced to produce higher grain yield. In terms of genetic traits analyses, all the studied traits exhibited high heritability (>60%) except panicle length. And in correlation studies, grain yield showed the significant positive correlation with 1000 seed weight, panicle length, effective tiller number per hill along with biological yield, straw yield and harvest index. Moreover, path coefficient analysis revealed that biological yield and harvest index showed a high and positive direct effect on grain yield. Thus, after studying different traits among ten varieties of Aman rice there after considering the three categories, hybrid varieties performed better followed by HYV compared to traditional rice varieties. And the Dhanigold variety might be recommended as a higher yield producing cultivar along with the economic return. Published on 2022-04-07 00:00:00
  • A Review of Recent Changes in Rainfall Trend in Sri Lanka

    • Abstract: The rainfall trend provides useful information for effective planning, and management of water resources and agriculture which also gives an insight into the climate change of a region. The rainfall trend varies with the use of different data periods, and therefore, this review attempted to analyse only the recent rainfall trend over Sri Lanka using published literature. The review examined 15 recently published manuscripts for monotonic trends and statistical tests used. Overall, the review identified the increasing tendency of rainfall in the entire country prominently towards the eastern segment. The review also comprehends upward trends of First Inter-Monsoon and North-East monsoon over the country. It is proposed to introduce effective water management measures to harness the opportunities created by increased rainfall and preparedness measures to reduce the anticipated risk.

  • Inhibitory Efficacy of Microbial, Botanical and Synthetic Fungicides
           Against Athelia rolfsii (Sclerotium STEM ROT) of Groundnut and Bambara

    • Abstract: Solutions for groundnut stem rot by Athelia rolfsii, which accounts for major groundnut and Bambara groundnut yield losses, were investigated. Three in vitro trials were set up to assess the inhibition of the growth of A. rolfsii using microbial, botanical and synthetic fungicides. The radii of A. rolfsii were measured and inhibition of growth were calculated. The inhibition of A. rolfsii by Trichoderma and Cladosporium spp. at 72 hours after inoculation (HAI) ranged between 28-82%. Inhibition of A. rolfsii by mancozeb (100% concentration) was significantly more than the control and the other pesticide rates at 144 HAI. The inhibition by all the synthetic fungicides ranged between 10-90%. Eucalyptus gum, plum seeds, bark of African locust bean tree extracts inhibited growth of A. rolfsii throughout. All plant extracts controlled A. rolfsii with the efficacy ranging between 8-100% inhibition. At 144 HAI, Eucalyptus (100% concentration) controlled A. rolfsii significantly more than all the other treatments, followed by Eucalyptus (50%) and Parkia bark (100%). Parkia 100% controlled A. rolfsii significantly more than other treatments followed by plum 100% and orange seeds 100%. Thus Sclerotium stem rot can be effectively managed using the Cladosporium cladosporioides, Trichoderma harzianum, mancozeb®, team® and plant extracts above. Published on 2022-04-07 00:00:00
  • Effects of Different Additives on the Quality of Composts Produced from
           Ordinary Garden Leaf Litter

    • Abstract: Disposal and proper management of garden waste in urban and semi-urban areas of Sri Lanka has become a problem due to several constraints. As an effective solution, production of compost by garden waste and other amendments can be introduced to home gardening. Further, it is vital to produce good quality compost to ensure the nutrient supply to the plant growth in home gardening. Hence, the ordinary leaf litter with high C:N ratio is necessary to supplement with other amendments to produce compost and reduce the C:N ratio. Therefore, the objectives of the present study were (i) to characterize the final composts after incorporating different amendments to leaf litter (ii) to find the best compost mixture leading to recommended level of C:N ratio for end use. By applying a mixing formula, five amendments were mixed keeping a constant weight of dry leaf litter; (i) dry leaf litter + Gliricidia leaves (Gliricidia sepium), (ii) dry leaf litter + Siam weed (Chromolaena odorata), (iii) dry leaf litter + cattle manure, (iv) dry leaf litter + spent poultry layer litter/poultry manure, and (v) dry leaf litter + urea. Only leaf litter compost was prepared as a control. Chemical properties of different composts were investigated and compared after 90 days of composting. The characterization included pH, EC, NH4+-N, NO3-- N and C:N ratio, available P, available K using standard analytical methods. The results were compared with the indices given by Sri Lanka standard (SLS) institute. According to the results chemical properties of final composts were largely varied with the type of initial raw materials used. The pH, EC were within the standard levels of compost. Different composts and control (un-amended) differed significantly (p
  • Effect of Carbon Balance on Competitiveness and Comparative Advantage of
           Rice Production Systems in Nigeria, West Africa

    • Abstract: Rice imports play a significant role in satisfying the high demand for rice in most West African countries including Nigeria. This has made these countries focus more on increased rice production. Climate change is a major issue for the sustainable development goals hence greenhouse gas emissions from rice production systems are of great concern. The study employed the Policy Analysis Matrix (PAM) to assess the effect of carbon balance on the competitiveness and comparative advantage of rice production systems in the northern region of Nigeria. The Ex-Ante Carbon Balance Tool was used to assess the carbon balance of rice production systems. Results of the analysis implied all production systems are competitive and have comparative advantage except for the irrigation system. Incorporation of carbon balance in the economic analysis reduces the comparative advantage of irrigated rice production system further. The study also revealed that the irrigation system benefits more from Government’s policies. It was observed that investing in technologies that would increase productivity will not guarantee low carbon emission hence the need to also go for climate-smart agriculture. This would advance climate-friendly rice production leading to a reduction in greenhouse gas emissions and steady rice supply. This will in turn lessen the necessity for distorting policies.

  • A Study on Changes in Amylose And Resistant Starch Contents of Selected
           Rice Varieties by Traditional Cooking Methods

    • Abstract: Resistant starch (RS) is considered to possess several health benefits. The amylose, RS and their relative changes with Total Starch (TS) in different varieties of rice from Northern Sri Lanka with the different traditional cooking methods were determined. For this study seven each of traditional and improved rice varieties were selected. In order to find the effects of traditional cooking methods, three traditional and two improved rice varieties were selected. Traditional rice variety Thattu Wee, contained the highest RS content. Different cooking methods reduced the RS contents of all the selected rice samples. The traditional rice variety Moddakaruppan, lost the highest amylose content except when pre-soaked and cooked without excess water while cooking with and without excess water led to a decrease in amylose related to TS contents except in Periyavellai. Variation in RS related to TS contents showed different changes with cooking methods and rice varieties. RS related to amylose contents decreased by cooking with and without excess water, except in Bw351 cooked without excess water (where there was no change) and with roasting, while pre-soaking and cooking without excess water increased the contents. Among the three traditional rice varieties selected for cooking, Periyavellai lost the least amounts of amylose and RS but the loss was more than that of Bw351. Published on 2022-04-07 00:00:00
  • Physiological Responses of Spring Wheat Cultivars Grown in Warm and Cool

    • Abstract: Rising levels of atmospheric temperatures in growing ecotopes are thought to affect physiological functioning of plants. Four wheat cultivars, UNZA II (heat tolerance), Loerie II (check), Nduna and Pungwa were tested in both warm and cool ecotopes for their acclimation capacity to subsequently enhance production. Using five replications, a randomised complete block design was used and data on canopy temperature (CT), stay green duration (SGD) and dry matter production and accumulation (DM) was collected and analysed using GENSTAT software version 18. Results revealed that all cultivars had 3oC low CT than their temperatures in cool ecotope in 2014 and 3oC to 6oC high CT than their cool ecotope in 2015. Cultivars terminated their DM production and accumulation in the warm ecotope 7 days earlier than in cool ecotope. DM production and accumulation was quick in 2014 and slows in 2015 in the warm compared to the cool ecotope. Pungwa showed superiority with 52.8% SGD and 39.8% SGD remaining at 28 days after anthesis in 2014 and 14 days after anthesis in 2015 in the warm ecotope, respectively when other cultivars had lost over 65% and 76% of the SGD and maintained its DM at physiological maturity in both seasons. Pungwa with longer SGD, low CT and more DM accumulation suggests the ability to support plant growth and could enhance wheat production in warm ecotope. Published on 2022-04-07 00:00:00
  • The significance of livestock as a contributor to global greenhouse gas
           emissions today and in the near future

    • Abstract: In animal agriculture, the greatest contributors to methane emissions are enteric fermentation and manure management. Enteric methane emissions were higher with ruminant animals while manure storage methane was higher with swine and poultry. The main course of agricultural nitrous oxide emissions is from the application of nitrogen fertilizers and animal manures. The most cost-effective way to reduce CH4 production is to improve feed efficiency. In low-intensity systems, CH4 production per unit product can be markedly reduced by improving feed quality and feeding intensity. Inhibition of methanogens, involvement of other H2 alternative sinks e.g. inclusion of dietary fat, can result in a reasonable reduction in CH4 production. Generally, some feed additives such as condensed tannins (CTs), fibrolytic enzymes and other factors e.g. methane inhibitors, vaccines, defaunating agents etc, have the potential to mitigate CH4 production from ruminants. However, there are also some disadvantages, e.g. they are costly and not economical to apply at the farm level, and many have only short-term effects on CH4 production thereby diluting the maintenance costs. The range of global mitigation potential to improve carbon sequestration and other factors are documented. Global and Sri Lankan scenarios on emissions and emission intensities from dairy production and the mitigating options are discussed. It is highlighted that removing animal agriculture is not a good solution to reduce greenhouse gas emissions. It is also suggested that combining productivity increases in crop and livestock sectors appears to be the most efficient way to exploit mitigation and food security co-benefits.

  • Contribution of non-timber forest products (NTFPs) utilization to the
           well-being of women: evidence from Nigeria

    • Abstract: This paper assessed the contribution of NTFPs to the well-being of women living in Ewekoro Local Government Area of Ogun State, Nigeria. Logistic regression and Ordered Logistic regression models were used to assess the contribution of NTFPs to the well-being of 120 women in the study area. The mean age, monthly household income, distance of homestead to forest and homestead to the nearest market were 47 years, $144.4, 2.0km and 1.8km respectively while 70.5% of the women used NTFPs as food. The housing dimension had the highest index of 0.537 while the overall index of 0.491 indicates a moderate level of well-being for respondents. NTFPs utilization significantly increased with household income and primary occupation but decreased with increasing age, level of education, distance from homestead to forests, distance to the nearest market and access to credit. Women’s well-being increased with utilization of NFTPs, being married, distance from homestead to the nearest market and access to credit but decreased with the distance of homestead to the forest, association membership and income. It is recommended that agricultural advisory and extension services in terms of NTFPs collection and utilization be provided; unconditional cash transfers and other consumption smoothening aids should be provided; necessary road networks should be rehabilitated or constructed, this will enhance NTFPs utilization; credit access should be provided for rural women, and rural women should be mobilized to form and/or join associations. Given that, NTFPs utilization contributes to the well-being of women, policies and programs that will enhance women’s utilization of NTFPs should be put in place. Published on 2021-12-31 00:00:00
