[en] Bangladesh is on the trajectory of rapid economic growth, and poverty, inequality, food insecurity and malnutrition are major problems. Fragile ecosystems are big challenge for agriculture, where saline, drought and submergence areas cover 1.09, 2.0 and 2.5 million ha, respectively out of 8.6 million ha of cultivable lands. Rice and other crops (other cereals, pulses and oilseeds) have low productivity, are prone to diseases and are affected by salinity, submergence and drought; and inadequate soil/water/fertilizer management. The IAEA has been supporting BINA a long time, providing projects and capacity building for scientists and laboratory development. Through the peaceful use of nuclear and other advanced techniques, BINA has developed 91 improved short duration, climate resilient and high yielding crop varieties of rice, pulses oilseeds and tomato so far. Over the past decades, Bangladesh made remarkable progress in crop improvement using mutation breeding and other advanced techniques. Short duration mutant variety (var. Binadhan-7) of rice alleviated occasional hunger and increased productivity. Salt tolerant rice varieties (Binadhan-8 and Binadhan-10) were adopted in 20% of saline prone areas. Submergence tolerant rice varieties (Binadhan-11 and Binadhan-12) were extended in 5% submergence prone areas. Mutant variety (Binadhan-14) of irrigated rice helped to accommodate additional crops in-between existing two rice in a year. Green Super Rice variety (Binadhan-17) saves 30% nitrogen fertilizer and 40% irrigation. Improved lentil (Binamasur-5 and Binamasur-6) and mung bean mutant varieties (Binamoog-5 and Binamoog-8) decreased major disease risks and increased yield by 80%. Short duration mutant mustard varieties (Binasharisha-9 and Binasharisa-10) facilitated to cultivate additional crop and increased cropping intensity. Mutant groundnut (peanut) (Binachinabadam-5, 6, 7 and 8) resolved salinity problems and increased yield by 40%. Rice straw application reduces potassium fertilizer application up to 25% and chemical amendment (split application of gypsum) is now practiced among farmers which result in higher yields in saline areas. Mulching and the use of crop residue in the field are popular in drought areas. Through dissemination of our technologies, we trained 30 000 farmers and 3000 extension personnel; implemented 30 000 demonstrations; 1500 field days and 150 workshops; and distributed 6000 tons of seed. Our future plans are the development of high yielding, short duration, nutrient-rich, premium quality and climate smart varieties; the improvement of local cultivars and landraces suitable for unfavorable and under-utilized ecosystems; and the validation and up-scaling of mutant varieties.
