“…Bangladesh is the third-largest rice producer in the world (Rahman et al, 2021). Rice is the leading staple food in Bangladesh, accounting for more than 80% of total food supply, and provides 66% of total protein requirements for daily food intake (Rahaman et al, 2020). Rice is grown on 11.4 million hectares of land, accounting for 77% of total cropped area and yielding 36.6 million tons of rice per year (BBS, 2020a).…”

Agrarian Bangladesh relies heavily on rice. Since independence, many varieties have been released and targeted to increase productivity, farmers' income, and food security. However, few gained widespread adoption. Moreover, farmers in the border regions are adopting exotic cultivars, and it's gradually spreading throughout the country. But, the reasons for adopting exotic rice cultivars are still unexplored. Using field data from 1,260 farm households and 42 focus group discussions, this study analyzes farmers' preferences for domestic and exotic rice varieties and identifies the factors of adoption linked to design national breeding programs and farmers' welfare. Findings show, exotic varieties (69%) monopolized the area coverage in the dry season, whereas in the wet season, domestic varieties (58%) dominated. Farmers select exotic varieties for their better yield and price, low production costs, high grain quality, resistance to pests and diseases, and ability to withstand stresses. Risk analysis shows domestic varieties adoption is riskier with lower returns. The empirical findings indicate that household characteristics, access to institutions and infrastructure, varietal characteristics, and weather condition, all play a significant role in adoption decisions. National breeding should focus on developing rice varieties in response to market demands and farmer preferences toward sustainable food security in Bangladesh.

This study aimed to investigate the cost-benefit per hectare of rice production in the haor region in Bangladesh. For doing so, the multi-stage sampling technique was used to collect cross-sectional data during 2018 from four haor districts producing rice in Bangladesh. To achieve the purpose, a total of 368 randomly selected farming households from Habiganj, Sunamganj, Moulvibazar, and Sylhet districts were surveyed using a structured questionnaire. Data analysis was done utilizing descriptive statistics and cost and return analysis. The result revealed that labor costs constituted the largest proportion of gross operating expenses, followed by fertilizer, irrigation, tillage, insecticides and herbicides, and threshing cost. The cost-benefit analysis finding also shows that rice is a profitable enterprise in the haor areas as the lower production cost compared to return. Because of the amount of input used and the price of output, the profitability differs between different seasons, however. The model shows that cost of seed, human labor cost, cost of TSP, cost of MoP, and cost of irrigation were the key factors that influenced rice production. This study also identified some of the problems related to rice production in haor areas. Lower output price, higher input price, unavailability of short growth duration high yielding varieties, and embankment damages, etc., are key obstacles to rice production. Therefore, this study provides the government's concerned authority with appropriate suggestions and policy recommendations to solve the farmers' issues that could boost rice productivity in the haor areas and contribute to food security and self-sufficiency in rice cultivation.

“…Bangladesh, with its predominantly agricultural economy, relies significantly on rice as a staple crop [1], which accounts for more than 80% of the total food supply and meets 66% of daily protein requirements [2]. In FY 2021-2022, rice cultivation covered an extensive area of 11.7 million hectares, representing 84% of the total cropped land area and resulting in an annual rice production of 38.14 million metric tons [3].…”

Rice contributes significantly to both food security and livelihoods in Bangladesh. Despite challenges such as an immense population growth rate and decreased arable land since gaining independence, Bangladesh has attained self-sufficiency in rice production by adopting modern rice varieties (MRVs). However, not all introduced MRVs have gained widespread acceptance among farmers due to concerns about productivity and profitability. Notably, BR11, an MRV, stands out as a prominently adopted rice cultivar during the Aman rice-growing season. This study aims to assess the levels of essential nutrient minerals (Na, K, Ca and Mg) and potentially toxic elements (PTEs) (Cd, Cu, Pb, Ni, Co, Fe, Mn, Zn, Cr) in the BR11 rice cultivar and also to evaluate associated health risks. The concentrations of Na, K, Ca and Mg (mg 100 g–1) in the sampled BR11 rice cultivar were found to be 4.4 ± 2.4, 108.5 ± 24.9, 3.4 ± 0.4 and 4.5 ± 1.1, respectively. Among the PTEs, Cd, Pb, Ni, Co, or Cr contents were below the detection limit, while Fe, Mn, Zn and Cu contents (mg kg–1) were 12.0 ± 4.0, 9.2 ± 1.5, 18.7 ± 2.7 and 2.9 ± 1.0. Comparisons of PTE contents in BR11 rice cultivars exposed to industrial activities with those cultivated in non-industrial zones did not reveal any statistically significant variations (p < 0.05). The estimated daily intake of nutrient minerals through the consumption of BR11 rice was significantly below the daily recommended dietary reference intakes. Likewise, the accumulation of PTEs in the BR11 rice cultivar was well below the maximum allowable concentrations recommended by WHO or FAO. Health risk assessments, involving the computation of non-carcinogenic and carcinogenic risks, did not indicate any concerning risk scenarios associated with the consumption of the BR11 rice cultivar. The data suggests that BR11 is a safe MRV for daily consumption, affirming its suitability for inclusion in the daily diet.
