Therefore, an improved system is needed to address the issues, a field experiment was conducted during 2011-2013 to evaluate system intensification with varying degrees of cropping systems and residue retention. Four cropping systems (CSE) namely CSE1: T. boro rice-T. aman rice (control), CSE2: wheat-mungbean-T. aman rice (wheat and mungbean sown using a power tilleroperated seeder (PTOS) with full tillage in a single pass; puddled transplanted aman), CSE3: wheatmungbean-dry seeded DS aman rice (DSR), and CSE4: wheat-mungbean-DS aman rice (all sown by PTOS with strip tillage) were compared. Two levels of aman rice residue retention (removed; partial retention i.e. 40 cm of standing stubble) were compared in sub plots. Grain yield was significantly higher (by 11%) when wheat was grown after DSR than PTR. Similarly, PTR and DSR (aman rice) produced statistically similar crop yields. Rice residue retention resulted a significantly higher (by 10%) wheat yield and a slightly increased (by 6%) mungbean yield than that of residues removed. The system productivity of CSE4 was significantly higher (by 10%) than CSE1 when averaged of the two years data. Partial aman residue retention gave significantly higher system yield than residue removal (by 0.6 t ha). After two years, no effect of CSE or partial aman residue retention was found on soil physical property (bulk density) of the top soil. Therefore, CSE4 along with residue retention would be more effective for sustainable crop production.","PeriodicalId":322702,"journal":{"name":"The Agriculturists","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122294226","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 paper also identifies farmers marketing activity and their production problems. Primary data were collected from 60 farm household’s survey using pretested semi-structured questionnaire during November to December, 2017. Farm level production and profitability were analysed by using net farm incomes and Benefit Cost Ratio (BCR) taking into account the variable cost and total cost. Applying descriptive statistics, the analysis showed that total cost of paddy production was higher in Bogura (BDT 44,555.3/acre) compared that of Gaibandha (BDT 42,199.5/acre) while net farm income was higher in Gaibandha (BDT 32992.2/acre) than Bogura (BDT 32475.9/acre). The analysis further showed that paddy production was profitable in both districts. BCR on the basis of variable cost and total cost indicated that return from paddy production was higher than cost which also ensures farmers profit in paddy production in both the districts. According to farmers’ opinion, disease infestation was the major production problem in Bogura district while both disease attack and natural calamities were the major production problems in Gaibandha district. Farmers’ suggested to reduce the cost of pesticides and they need marketing facilities to sell their product. They also suggested to establish cold storage facilities which create the opportunity to get fair price for their product.","PeriodicalId":322702,"journal":{"name":"The Agriculturists","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123593689","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}

Thus, its daily consumption is pretty normal. Although, a number of researches have been done on river fish and its consumption, there seems a few in the public that specifically studied consumer preference for sea fish consumption in Bangladesh. This study, therefore, explores the consumers’ preference for sea fish consumption in Dhaka city of Bangladesh. A cross sectional survey design was followed to collect data from 120 respondents in four quota sampled areas of the city, namely; Uttara, Khilkhet, Mirpur and Jatrabari. The results revealed that 20 species of sea fish were usually brought to the markets patronised in the selected areas, but 17 were commonly consumed. The consumers mostly preferred Tenualosa ilisha (95.83%), Pampus chinensis (91.67%), Penaeus monodon (75.0%), Lates calcarifer (74.17%), Euthynnus affinis (62.5%) and Harpadon nehereus (58.33%) for their taste whereas, Pama pama (33.33%) and Setipinna taty (46.67%) were preferred for lower price. The average monthly household sea fish consumption was 5.49 kg. Age, level of education, gender, annual income and religious view were found to have significant positive association with household sea fish consumption. Respondents preferred sea fish for health benefits related to heart, eye-sight, nutrient enrichment, diseases protection and prevention of depression. However, irregular supply of sea fish and higher price were pointed by the respondents as the main constraining factors to sea fish consumption. Generally, Bangladesh is blessed with vast sea fish resources, but consumers’ accessibility need to be strengthened.","PeriodicalId":322702,"journal":{"name":"The Agriculturists","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130020572","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}

In order to determine the values of Kc for jute, an experiment was conducted at the Irrigation and Water Management Division of Bangladesh Agricultural Research Institute (BARI), Gazipur. An improved jute variety BJRI Tosa-2 (O-9897) was used in this experiment. The study examined growth and yield of the jute in terms of four irrigation treatments distributed over 7-28 days intervals. The treatments were so designed that drainage was allowed between the consecutive irrigations. Irrigation at 14days interval produced the highest dry fiber yield (3.93 t/ha) and was considered to be suitable for estimating seasonal crop evapotranspiration and Kc values. The seasonal crop ET was 549.13 mm under this treatment. The Kc values of jute at initial, development, mid-season and late season stages were found to be 0.72, 1.39, 1.26 and 0.46, respectively. As there is no FAO-recommended Kc value for this crop, this locally calibrated values can be used for similar climatic conditions of Bangladesh and elsewhere. Therefore, based on Kc value, it can be recommended that jute can be irrigated by equal amount of water needed for crop evapotranspiration (ETc) for different growth stages (141.05, 142.57, 167.34, and 84.30 mm) to get maximum dry fiber yield. \u0000The Agriculturists 2018; 16(2) 115-122","PeriodicalId":322702,"journal":{"name":"The Agriculturists","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133637190","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}
