Binadhan-10 & Binadhan-11 are climate smart stress tolerant high yielding\nrice varieties (yield > 4 t.ha-1) have saline tolerant EC up to 12 ds/m and\nsubmergence tolerant up to 20 - 25 days capacity. The present study was an\nattempt to analyze the yield gap of stress tolerant varieties Binadhan-10 &\nBinadhan-11 in some selected areas of Bangladesh. The objectives of the\nstudy were: 1) to estimate the yield gap of Binadhan-10 &-11 growers among\nthe study areas; 2) to identify the factors affecting the yield of these variety;\nand 3) to suggest some policy guidelines to minimize the yield gap. The\nstudy was conducted in eight Binadhan-10 & Binadhan-11 growing areas in\nBangladesh. In this study, four districts namely Satkhira, Khulna, Barishal,\nand Coxâ??s Bazar were used for Binadhan-10 and Mymensingh, Jamalpur,\nSherpur and Sunamgonj were taken for Binadhan-11. It is based on primary \nlevel data from eight sub-districts among the study areas. A total of 240 farmers\nwere randomly selected (30 from each location) to collect the data with a\npre-designed questionnaire. Farmer were grouped according to saline affected\nand not-affected for saline tolerant variety Binadhan-10 and not affected,\naffected (1 - 10 days) and highly affected (10 - 20 days) for submergence\ntolerant rice variety Binadhan-11 to identify existing yield gap. Tabular\nas well as Zandstra method were applied for analysis the data. The study\nalso found factors affecting the gap and some policy guidelines to minimize\nthe gap.
