“…More than 60% of the area is covered by these two varieties during Boro season [19]. Currently, Boro cultivation area recorded for 61% of total cropped area in the Rabi season, which contributes 55% of total rice production in the country [18]. Our findings are also similar to this results.…”

“…Whereas production contribution of Aman season was higher from 1969-70 to 1997-98. Boro season is less vulnerable to rice disease, pests and other natural calamities and government incentives on Boro cultivation more specifically on irrigation facilities increase the Boro cultivation area [6,18]. Moreover, after the release of two Boro mega varieties, BRRI dhan28 and BRRI dhan29 in 1994, the second silent green revolution of rice has occurred in Bangladesh.…”

“…Our findings are also similar to this results. The maximum growing degree days, long vegetative growth, sunny weather and high amount of fertilizer utilization capacity favors the potential yield of rice during Boro season [18]. Moreover, the price of Boro rice is higher compared to other seasons which is also a key regulator of the intend of farmers to cultivate Boro rice [20].…”

Bangladesh positioned as third rice producing country in the world. In Bangladesh, regional growth and trend in rice production determinants, disparities and similarities of rice production environments are highly desirable. In this study, the secondary time series data of area, production, and yield of rice from 1969–70 to 2019–20 were used to investigate the growth and trend by periodic, regional, seasonal and total basis. Quality checking, trend fitting, and classification analysis were performed by the Durbin-Watson test, Exponential growth model, Cochrane-Orcutt iteration method and clustering method. The production contribution to the national rice production of Boro rice is increasing at 0.97% per year, where Aus and Aman season production contribution significantly decreased by 0.48% and 0.49% per year. Among the regions, Mymensingh, Rangpur, Bogura, Jashore, Rajshahi, and Chattogram contributed the most i.e., 13.9%, 9.8%, 8.6%, 8.6%, 8.2%, and 8.0%, respectively. Nationally, the area of Aus and Aman had a decreasing trend with a -3.63% and -0.16% per year, respectively. But, in the recent period (Period III) increasing trend was observed in the most regions. The Boro cultivation area is increasing with a rate of 3.57% per year during 1984–85 to 2019–20. High yielding variety adoption rate has increased over the period and in recent years it has found 72% for Aus, 73.5% for Aman, and 98.4% for Boro season. As a result, the yield of the Aus, Aman, and Boro seasons has been found increasing growth for most of the regions. We have identified different cluster regions in different seasons, indicating high dissimilarities among the rice production regions in Bangladesh. The region-wise actionable plan should be taken to rapidly adopt new varieties, management technologies and extension activities in lower contributor regions to improve productivity. Cluster-wise, policy strategies should be implemented for top and less contributor regions to ensure rice security of Bangladesh.

“…By 2050, the population of Bangladesh will reach 215 million (United Nations, 2017) necessitating the production of additional 10 million tons of rice (Mainuddin and Kirby, 2015). Therefore, it is critical to select rice varieties that produce a high yield, have good grain quality, low production cost, are resistant to pests and diseases, and can withstand stresses (Mariano et al, 2012;Laborte et al, 2015;Kabir et al, 2019;Mainuddin et al, 2021). This study demonstrated that exotic rice varieties have higher yields and prices than domestic varieties.…”

“…Farmers prefer cultivating exotic rice cultivars to avoid yield losses due to abiotic and biotic stresses (Kabir et al, 2019). Additionally, the low production costs and high profit margins enable farmers to switch (Mainuddin et al, 2021) from domestic to exotic varieties. Food security and household welfare are two avenues by which the adoption of improve varieties may benefit farmers.…”

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.

Rising population and demands for rice as a staple food have created severe stress on freshwater availability for paddy cultivation. The literature suggests that conventional irrigation techniques are inadequate to overcome the water constraints arising from drought and extreme weather conditions. In the past few decades, there is an upsurge of scientific exploration of agricultural techniques in reinventing traditional methods of irrigation. Recently, alternate wet and dry irrigation (AWDI) method has shown great promise regarding profitable rice cultivation with limited water supply. The AWDI method is a trending water management system, which inundates rice fields with intermittent wet conditions followed by a dry period. This not only ensures adequate water supply but increases crop yield and water productivity index (WPI). The AWDI also helps in reducing parasitic mosquito population in the rice fields by minimizing the field flooding period and curtailing a major part of their life cycles. This review proposes a novel approach of emphasizing AWDI method as an important agricultural tool for supplementing rice fields with limited freshwater, increasing crop yield, and monitoring parasitic mosquito populations. The major objective of this study is to report the state‐of‐the‐art scenario of AWDI method, critically analyze the research gaps related to conventional methods of irrigation and appreciate the futuristic long‐term benefits of AWDI method. Literature survey was performed using search engines like Scopus, PubMed, Google Scholar, Research Gate, Science Direct, and Google Scholar. Comprehensive appraisal of resources (both offline and online) and critical evaluation of AWDI technicalities revealed that the AWDI reduced water usage by 45%, enhanced crop yield and improved WPI in paddy fields in the Asian sub‐continent. The AWDI also curtailed the propagation of lethal mosquito species (Cx. tritaenorhynchus, Cx. vishnui, and Cx pseudovishnui) in rice fields. Therefore, the current study endorses AWDI as a promising substitute of conventional irrigation and a novel approach towards fulfilling water constraints that may be practiced anywhere in the world.
