“…Microbial activities also grow with increasing the values of moisture content and increase the losses of quality (Ruska and Timar 2010). These results were consistent with the findings of Akter et al (2015). Seeds stored in PICS bag and super grain bag retained the highest seed germination for a longer time (Khatri et al 2019) than other tested seed storage materials.…”

Storage loss of rice seed in terms of quality parameters is higher in Nepal due to lack of information about the effect of storage materials. Laboratory experiment was conducted to evaluate the effect of storage materials and storage period on quality parameters of rice seed (Oryza sativa L. cv., Bahuguni dhan-1). Rice seed was stored in seven storage materials (metal bin, plastic bin, super grain bag, PICS bag, plastic bag with jute sack, jute sack and earthen pot) in Completely Randomized Design with three replications at the Seed Laboratory of National Wheat Research Program, Bhairahawa, Rupandehi, Nepal from March to July, 2021. Seed moisture content and germination percentage were recorded before storage and after one, three and five months of storage. The population of two insect pests rice weevil and maize weevil was recorded after five months of storage. The result revealed that all the seed quality parameters under study were significantly influenced by storage materials. PICS bag followed by super grain bag was found to be superior in terms of seed moisture content, germination percentage and seed health throughout the storage period. Seed in the indigenous storage materials (earthen pot and jute sack) lost their quality significantly throughout the storage period. Future research strategies should focus on seed quality study under several indigenous storage materials found in Rupandehi district of Nepal.

“…There is a lot of evidence in Bangladesh that farmers quit hybrid rice cultivation due to the high rate of failure of germination of the seeds when planted (Pervez 2018). Research brought out the seed quality of 15 hybrid rice seed suppliers, with seeds from different companies, and showed that only 37.7 to 85.7 % of seeds were healthy (Akter and Hossain 2015).…”

Purpose: Bangladesh faces a growing food demand from a growing population under the continuous shrinking of arable land. Most Bangladeshi farmers produce inbred rice. Hybrid rice has been shown, in China, to be far more productive per hectare. Bangladesh cannot feed itself long-term without ample produce of hybrid rice. Yet, fewer Bangladeshi farmers are growing hybrid rice at present; they perceive hybrid rice cultivation as too risky. The present study was conducted to define the yield risks of hybrid rice and develop management strategies to allow hybrid rice to contribute more to food production.Research Method: Both quantitative and qualitative methods were used to evaluate the risks of hybrid rice production from the farmers' perspective and the experts'. Three hundred fifty-four randomly-sampled hybrid rice farmers were interviewed with key informants, focus group discussions, experts' opinion surveys, and workshops. A fuzzy triangular scale was used in calculating the yield risks of hybrid rice production.Findings: From the results, unexpected yield performance, germination failure, unavailability of seed in sowing seasons, and crop failure due to pest infestation were identified as the critical yield risks. A regression model determined that education, family income, innovativeness, hybrid rice cultivation experience, and rice selling in public procurement are lower yield risks in growing hybrid rice. Therefore, educated farmers from high-income families, innovative farmers, experienced farmers, and farmers who sell rice in public procurement face lower yield risk in hybrid rice production.Originality/value: This study mainly identified the critical risk and management strategies for hybrid rice production in Bangladesh. The policy advises encouraging hybrid rice cultivation by reducing yield risk, which is also offered.

“…The production and supply of quality seed in rice plays a vital role to meet the growing population. It has been shown experimentally that only by using good quality healthy seed, rice yield could be increased by 10-15% (Akter et al, 2015). In rice, there is no much problem in seed storage if the crop is well maintained during production period.…”

“…The antioxidant substances like ascorbic acid, tocopherol and glutathione had a positive effect on the seedling vigour (Basra et al, 2006;Draganic and Lekic, 2012). Similarly, seed treatment with biofungicide has been found as superior in increasing germination and vigour in rice seeds (Akter and Hossain, 2015). Therefore, an experiment was conducted in the rice variety ADT (R) 46 seeds by treating with different antioxidants as to manage its poor storage behavior.…”

However, rice seed stored for long-term is invariably exposed to different climatic adversities like extreme summer, winter and monsoons etc. requires a great deal of effort to safeguard it. Therefore, seed storage is an important aspect of any sound seed program, because badly stored seeds are not much helpful to yield healthy and vigorous plant. A good quality seed may also be seriously deteriorated if stored under sub optimal condition. Considerable amount of works have been done on storage of rice seeds in relation to varied storage conditions in different parts of the
