Survey-based data were collected through pre-tested questionnaires from some purposively selected 42 poultry farms erected within the areas of Mymensingh, Gazipur, Netrokona, and Jamalpur districts. A large amount of poultry litters were generated from broiler and layer farms daily. Most of the farmers dumped this litters in open places (50%) which caused a serious environmental and health hazards. A self-aerated composting technique was designed and developed to effectively manage and mitigate the environmental and health hazards evolving from poultry litters. A compost heap was prepared with rice straw, water hyacinth, and poultry litters with the proportion 1:2:4 respectively by weight at the optimum C:N ratio of 30:1 incorporating the provision for air entraining into the bulk compost heap. Temperature and moisture contents at time interval of three days, and pH, C/N ratio, volume, and microbial properties at time interval of seven days were observed throughout the composting period of 60 days. Analysis was accomplished taking representative samples from the compost heap using the random sampling technique. The quality of compost in terms of nitrogen, phosphorus, potassium, and organic carbon was evaluated in accordance with the Indian and Australian Standards. This technique is found environmentally safe, functional and cost-effective. The developed self-aerated composting technique would be an alternative option for safe management of poultry litters for the farmers in the rural areas.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90526620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All of the original data used in this investigation was acquired from 50 farmers who grew the Binamasur-10 variety, through a pre-planned interview schedule and data collected from April to May 2021. To estimate profitability in this study, costs and return evaluation were done using variable value and total price principles. A total of Tk. 51370.47 was spent on production costs per ha, of which 35% were fixed costs and 65% were variable costs. The cost in Nachole was Tk. 51799.24 per ha, while the cost in Chapainawabganj Sadar was Tk. 50941.70 per ha. In the studied locations, the average net return was Tk. 61909.25 per ha, greater in Chapainwabganj Sadar (Tk. 74050.57 ha-1) than in Nachole (Tk. 49767.92 ha-1). The BCR was assessed to be 2.20 based on overall cost, which was similarly higher in Sadar (2.45) than in Nachole (1.96), both of which are located in the Chapainawabganj district. The 88% of respondents mentioned that shortage of Binamasur-10 seeds was the top constraint. Other restrictions include the lack of information (51%), lack of technical understanding (40%), increased insect infestation (38%), untimely rainfall (36%), and high insecticide costs (19%). Farmers in these regions ought to have access to superior lentil seeds at reasonable market rates as a result. Therefore, the current study is a modest attempt to investigate if the availability of pulse seeds of higher quality at a lower cost could increase production in the chosen areas.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84434052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studying the phytosociological attributes of weeds in a humid area provides insight into the dynamism and relative importance of each weed species peculiar to the area which is very important in understanding crop-weed interrelationships and highlights the bases for effective management stratages. An experiment was conducted in 2019 and 2020 cropping seasons at the Department of Crop Science Teaching and Research Farm, University of Calabar, to identify the predominant weeds in the farm area and assess their responses to polyethylene colour and soil solarization duration. The experiment was a factorial combination of two polyethylene colour (black and transparent) and five in situ soil solarization durations (0, 8, 12, 16 and 48 weeks), laid out in randomized complete block design (RCBD) with three replications. Data were collected on the phytosociological characteristics of the weeds on four weekly intervals up to the twentieth week. The predominant weeds identified in the experimental area were Eragrostis ciliaris L., Cynodoon dactylon L., Panicum maximum Jacq., Axonopus compressus Beav., Kyllinga bulbosa Beav. and Kyllinga erecta Schum., Gloriosa superba L., Ipomoea involuncrata P., Calapogonium mucunoides Desv., Aspillia bussei O.

Twenty different wheat genotypes were planted in the fields over the course of six different treatments spaced 10 days interval following a Randomized Complete Block Design (RCBD) with three replications. A high degree of significant variation was observed for all the characters studied. Estimates of the genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) revealed that the phenotypic coefficient of variation was higher than the genotypic coefficient of variation, which indicates a large effect of environment on the expression of the characters studied. The highest estimates of PCV and GCV were observed for grain yield/plant followed by the number of tillers/plant. Heritability estimates revealed that characters like pollen fertility and sterility exhibited the highest heritability followed by days to maturity. The genetic advance was higher for grains/plants followed by plant height. Grain yield showed significant and positive phenotypic and genotypic correlations with grains/plant and 100-grain weight. Phenotypic path analysis revealed a significant direct positive effect of 100-grain weight on grain yield. Principal component analysis (PCA) revealed that the first five components having greater than one Eigenvalue contributed to 83.41% variability. The heat stress tolerance indices revealed that Bijoy and BARI Gom-25 had the lowest tolerance index (TOL), stress susceptibility index (SSI) values and highest yield susceptibility index (YSI) values which show more tolerance and less susceptibility to terminal heat stress and produce moderate grain yield under terminal heat stress. Balaka and Shughat had the highest mean productivity (MP), geometric mean productivity (GMP), and stress tolerance index (STI) values and produce high yields under terminal heat stress conditions.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74104092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Especially the Omega-3 fatty acids and essential amino acids present in the fish had beneficial effects on the Coronary Heart Disease (CHD) and reduce the Protein Energy Malnutrition (PEM) in these countries. Being an island and expanding aquatic resources, Sri Lanka has plenty of fish resources, but, the consumption of small fish among the population has decreased in the country over the past 20 years. So, it is essential to be aware of the nutritional content of particular fish species that are assumed to be undervalued. This study, it was aimed to compare the nutritional composition of three local fish species namely, Amblygaster sirm, Sardinella brachysoma and Oreochromis niloticus. Proximate composition, pH and calorific values of the fish meat were determined by standard methods and other relevant protocols. The fatty acid profiles of oils of the fish were examined using the GC-MS method. Results showed that there were significant (p<0.05) differences among the three fish species with respect to the proximate parameters and fatty acid composition. When compared to the other two species, S. brachysoma exhibited the highest quantity of crude protein and fat, with 19.23% and 4.85% respectively. Among three fish species, the total mono-unsaturated fatty acid (MUFA) and poly-unsaturated fatty acid (PUFA) contents ranged from 31 to 38%; particularly, quantities of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were found to vary from 2.69 to 3.7% and 7.5% to 9.2%, respectively. Considering the Omega-6:Omega3 ratio, A.sirm (0.3), S. Brachysoma (0.69) and O. niloticus (6.5) were reported balanced values. In conclusion, these three fish species can be potential raw materials to produce high-value fish products.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"258263 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77535604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Replacing HYVs in the local cultivars-intensive areas would increase rice production and strengthen national food security. To do this, it is necessary to identify the determinants of cultivating local rice varieties by farmers. Therefore, this study used fractional logistic regression and a cognitive approach in the popular Aman and Boro season local rice variety-intensive areas to find out the causes of cultivating local rice varieties. The findings reveal that the main cause is the adverse ecology, where HYVs are not suitable, but local cultivars have physiological attributes to be well suited. The local cultivars are growing mainly in the Haor and flood-prone ecosystems, where modern varieties can not be sustained. The profitability of local rice cultivars is better than the HYVs as well. Moreover, farmers’ socioeconomic conditions such as age, education, occupation, income, and farm size influence the cultivation of local rice varieties. The yield, land topography, and market price also have an impact on the adoption intensity of local cultivars. The farmers also opined that the special grain quality of the local rice cultivars attracts the farmers, consumers, and market price that lubricate the intensity of local rice varieties adoption in the specific areas of Bangladesh. The findings of this study would be helpful for the rice breeders, scientists, and policymakers to develop suitable modern rice cultivars and management packages for boosting rice production in the targeted local rice cultivars intensive areas of Bangladesh.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84093495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of the study was to assess the effect of Rhizobium inoculum on the growth, yield and quality of soybean varieties. In this regard, five different rates of Rhizobium inoculum were applied on eight distinct soybean varieties namely Shohag, BARI Soybean-5, BARI Soybean-6, PB-1, Binasoybean-1, Binasoybean-2, Binasoybean-3 and Binasoybean-4. The experiment was set up using a randomized complete block design with three replications. Soybean varieties showed variability in terms of plant stature, number of branches plant-1 and number of nodules plant-1 at different days after sowing. Among the varieties, Binasoybean-4 produced the tallest plant at 45 and 60 DAS and at 60 DAS variety PB-1 produced the tallest plant. At 45 DAS Binasoybean-2, at 60 DAS BARI Soybean-6 and at 75 DAS Binasoybean-4 produced the highest number of branches plant-1. In case of nodule production, Binasoybean-3 produced the highest number of nodules palnt-1 at 45, 60 and 75 DAS. Inoculation of seeds with 100% of RD of Rhizobium gave maximum plant height, number of branches plant-1 and nodules plant-1. It is noticed that Binasoybean-4 with the application of 100% of RD of Rhizobium inoculum produced the tallest plant and number of branches plant-1 at 45 DAS but at 60 DAS, though the tallest plant was found in the variety Binasoybean-4 with 100% of RD of Rhizobium inoculum but it was statistically identical to Binasoybean-3 with 100% of RD of Rhizobium inoculum. Binasoybean-4 with 100% of RD of Rhizobium inoculum also gave maximum number of branches plant-1 at 75 DAS. But Binasoybena-3 with 100% of RD of Rhizobium inoculum produced the highest number of nodules plant-1 at 60 DAS. In case of variety Binasoybean-1 performed superiorly in terms of all the yield and yield contributing characters. Application of 100% of RD of Rhizobium inoculum also showed superior performance. The highest seed yield (2.92 t ha-1) was recorded in Binasoybean-3 with the application of 100% of RD Rhizobium inoculum. The highest protein content was also documented in this treatment combination. Finally, it may conclude that Binasoybean-3 with the application of 100% of RD Rhizobium inoculum might be recommended for maximizing seed yield and to get best quality soybean.","PeriodicalId":15283,"journal":{"name":"Journal of Bangladesh Agricultural University","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81905186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to measure the prevailing levels of traffic induced noise pollution at the core academic points and to assess the impacts of noise pollution on students’ health at BAU. The recorded Lave ranges from 55–85 dB. The Lave ranges from 79–85 dB throughout the whole day at FoA and FoAH. The Lave at these two core academic points are almost the double than the permissible limit of 45 dB. The Lmax pressure (96 dB) at Jobber moor during the noon is the maximum inside the whole BAU campus. The movement of traffic vehicles is responsible as the main sources of these noise. The noise level indices and their degree of fluctuation as given by Leq, Lnp, and NC are higher in roadside locations namely at FoA, FoAH, FoAERS. In terms of noise pollution, three of the sampled areas namely FoA, FoAH, and KR market show ‘moderate risk’ (Lave: 81 dB) during the morning whilst, the FoAH possessed the ‘high risk’ with the Lave of 85 dB. The results show that the FoA, FoAH, KR market, Jobber moor, and administration building can be labelled as the highest zone of noise level intensity. Due to excessive noise, university students are facing disorders like irritation, headache, nervousness, insomnia, anxiety, hearing problem, and hypertension. Controlling noise pollution is an absolute necessity for BAU to ensure noise-less academic culture whilst the dwellers of BAU is in the risk of serious noise-related health hazards.
