The study analyzed profitability and productivity of dairy milk production from a survey of 70 respondents (farmers and market actors) in Dhaka region. Responsible factors that affect dairy milk production were identified using the Cobb-Douglas production function. The findings unveil that significant coefficients of variables exhibit positive impact on the dairy milk production. It is possible for dairy farmers to enjoy sufficient profits from milk production since earned gross return and net return were Tk. 1099 and Tk. 594, respectively against the total cost of production Tk. 487.83 per cow per day. Average production of milk per cow was 12.5 liters. The estimated Benefit Cost Ratio (BCR) was 2.17 that is dairy farmers earned Tk. 2.17 investing one taka in dairy farming. Int. J. Agril. Res. Innov. Tech. 12(1): 182-187, June 2022
Though the production of maize and the area under cultivation has accelerated, the rate of increase in production is not satisfactory due to its increasing demand with the continuous expansion of the dairy and poultry sectors in Bangladesh. The intended study aimed to identify the factors affecting the production of maize and whether the resources were utilized optimally in the production process. Required data were gathered from 130 maize growers, who were taken through simple random sampling from two districts, Manikganj and Rajshahi, of Bangladesh, through the interview with a pretested questionnaire. The impact of several factors on the productivity of maize was computed with the help of the Cobb-Douglas production function. The study revealed a significant positive impact of seed, land preparation, fertilizer and water management on the final output of maize. Although maize cultivators earned a decent profit, inefficient uses of resources were practiced. Seed and fertilizer were underutilized while labour was over-utilized in the production process. The sampling frame was selected purposively to represent the intensive maize producing area. Farmers shifted to maize cultivation progressively but the high price of seeds, natural calamities and low price of grains may affect production in future. SAARC J. Agric., 20(2): 93-104 (2022)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
