Sesbania – An Important aspect of INM for sustainable productivity of rice: A review
Author(s): Ramyajit Mondal and Saumi Goswami
Abstract: Population explosion is now a days a major factor that affects the food production in our country and thus quality food grain production in sufficient quantity without damaging the soil quality, productivity and fertility is one of the biggest challenges in the present agriculture scenario. Huge amount of chemical fertilizers, pesticides are very common and traditional solution for higher production of crop and for pest management purpose. But, due to lack of judicious application of such chemicals soil fertility is declining very rapidly and that is linked up directly and indirectly with poor nutrition and health of human being. This situation is severe in case of cereal production especially in case of rice where, chemical use is much more. In this context, practice of green manuring is the spark in dark to a great extent. Leguminous Green manure crops can meet a substantial portion of N requirement of rice and provide organic matter to the soil to maintain soil fertility. Sesbania aculeata (Dhaincha) can be useful alternatives to resource poor rice farmers if applied as green manure. Being a leguminous green manure crop it has several advantages over chemical fertilizers like it improves soil physical, chemical and biological health, promote microbial activity in soil, maintain nutrient balance, enrich the soil with organic matter etc. By addition of huge biomass Dhaincha increases rice yield besides improving soil quality. The highest rice yield was obtained when rice and Dhaincha were grown at 2:1 ratio in 20 cm wide rows. Effect of green manuring with Dhaincha on growth and yield of direct sown and transplanted rice have also been studied by different scientists.
