“…In addition, grains per panicle were significantly higher in the CF-treated rice; however, the effects of MNC fertilizers on grain quality were non-significantly ( p > 0.05) different except for grains/panicles (Table ), indicating the MNC fertilizers as a suitable alternative to CF. Besides, the total rice production was lower in MNC fertilizer treated plants as compared to CF-treated ones; however, it was higher than the average rice production in Bangladesh …”

This study investigated the comparative effects of mixed nanocomposite (MNC) fertilizers as an alternative to commercial fertilizers (CFs) on endophytic symbiosis and nutritional properties of rice grains. We synthesized MNC fertilizers with different concentrations and characterized them by using scanning electron microscopy and Fourier transform infrared spectroscopy. The CF was applied as per the method followed by local farmers; however, for MNC fertilizers both foliar and soil applications were done. Comparative analysis of growth and development, rice–endophyte symbiosis, and nutritional properties of rice grains was conducted. The panicles per hill, length of panicles, grain per panicles, 1000-grain weight, and dry matter of rice plants treated with MNC fertilizers were found to be not statistically ( p > 0.05) different compared to those of CF. However, growth parameters were significantly ( p < 0.05) higher in MNC fertilizer-treated crops than in CF-treated crops. Several predominant endophytes such as Penicillium spp., Aspergillus fumigatus , Rhizopus spp., and Fusarium spp. that could have significant effects on the enhancement of growth and nutritional properties of rice grains were identified in rice plants treated with MNC fertilizers at different concentrations. Contrarily, stem-associated Cercospora spp. was found in the CF-treated field and fission yeast was observed in the blank-treated field. In addition, the contents of proteins, fibers, carbohydrates, energy-yielding components, vitamin A, and minerals were significantly increased in rice plants treated with MNC fertilizers. Thus, we would like to conclude that MNC fertilizers could be one of the most potential alternatives to CFs for achieving better rice–endophyte symbiosis as well as nutritional improvements in rice grains for sustainable production.

“…This holds true for South Asia as well [3,4]. Rice covers 76% of the total crop area, of which 84.7% is cultivated with modern varieties and the remaining 15.3% with local traditional varieties [5]. Currently, rice is grown on 11.4 million hectare (ha) of land and its production is close to 34.4 million metric tons (MT) [6].…”

“…According to government assessments in 2017, about 16,000 ha of farmland were fully lost and 560,000 ha of standing crops were partially damaged. Although data based on a comprehensive evaluation of the August 2017 flood-affected food crops are unavailable, Aman rice in low-lying areas was probably the most affected [5,21]. In addition to drought, Bangladesh has the largest rainfed crop ecosystem; it too is prone to submergence [22,23].…”

Adoption Trend of Climate-Resilient Rice Varieties in Bangladesh

et al. 2022

Rice is a major crop in Bangladesh that supports both food security and livelihoods. However, a need remains for improved productivity and adaptation to the risks associated with climate change. To accomplish this, the increased adoption of climate-resilient and high-yielding rice varieties can be beneficial. Therefore, we conducted a study in Bangladesh over three consecutive years: 2016, 2017, and 2018. The scope of the study included the major cropping season (wet), Aman. The yield advantages of climate-resilient rice varieties were evaluated and compared with those of the varieties popular with farmers. We included new stress-tolerant varieties, such as submergence-tolerant rice (BRRI dhan51 and BRRI dhan52) and drought-tolerant rice (BRRI dhan56 and BRRI dhan71), along with farmer-chosen controls, in the study. We conducted the evaluation through on-farm trials to compare the varieties in both submergence- and drought-affected environments. The seasonal trials provided measured results of yield advantages. The participating farmers were also studied over the three-year-period to capture their varietal adoption rates. We calculated both the location estimated yield advantages (LEYA) and the location observed yield advantages (LOYA). The results revealed that, under non-stress conditions, the grain yields of climate-resilient varieties were either statistically similar to or higher than those of the farmer-chosen controls. Our study also revealed a year-to-year progressive adoption rate for the introduced varieties. The study suggests that the wide-scale introduction and popularization of climate-resilient varieties can ensure higher productivity and climate risk adaptation. The close similarity between LOYA and LEYA indicated that the observational and experiential conclusions of the host farmers were similar to the scientific performance of the varieties. We also found that comparison performed through on-farm trials was a critical method for enhancing experiential learning and obtaining an accurate estimation of yield advantages.

“…Rice is Bangladeshi's staple food as it is consumed @367 gm/person/day by 99 percent of the population, supplying around 75 percent of the calories and 55 percent of the protein in the average daily diet [4][5][6]. Although steady rice supply has significant consequences for food security, many see food security as associated with achieving selfsufficiency in rice production [7].…”

This study was carried out to evaluate the performance of BRRI cultivars, identifying criteria and constraints as well as factors influencing the intensity of BRRI cultivars adoption in Aus season on the farm households in Mymensingh district. The data were collected through structured questionnaires from a total of 390 randomly selected rice farmers from thirteen Upazila of Mymensingh district. The study employed descriptive statistics and Tobit censored regression to determine the adoption and yield status; and adoption intensity determinants. In addition to a total of thirteen FGDs and expert panel interview was conducted to verify the collected data. The results show that 82.04 percent of the area in Mymensingh district was cultivated with rice variety developed by Bangladesh Rice Research Institute (BRRI) with an average yield of 4.05 t/ha during the Aus season. The findings of the Tobit censored regression indicate that schooling, distance to the local market, training, price variation, taste and preference, amount of cultivated varieties, yield variability were the significant factors of the intensity of BRRI varieties adoption in Aus season. The study's results suggested that breeders should also emphasize the choice of farmers while developing varieties. In addition to developing new rice varieties, BRRI, Department of Agricultural Extension (DAE), Bangladesh Agricultural Corporation (BADC) and other seed producing organizations need to work together to provide the farmers with good quality seeds of BRRI varieties, which will increase the total production of the country, thus helping to ensure food safety.
