Residue Recycling: Organics,inorganics,microbes and Brassinolide on Productivity of Rice V. Thirumurugan

In Rice based cropping system after harvest of Rice crop left over stubbles not suitable for animal feed because it mixed mith mud so it could be converted as organic source of nutrients by introducing decomposing organisms. Livestock population is in diminishing trend and it caused lot of demand on Farm yard manure and recycling of Paddy stubbles is an viable alternative to supply nutrients as well as eco friendly. In Rabi rice cultivation low light intensity is an major concern for rice productivity. Foliar spray of growth harmone Brassinolide at panicle initiation and flowering stages to overcome low light intensity and increase the productivity of rice. Foliar spray of DAP, potassium chloride and Zinc sulphate to minimize the nutrient deficiency at critical stages of crop growth. Indescriminate use of nitrogen leads to losses in the soil plant system in addition to this reduced nitrogen use efficiency and also caused water pollution. The neeed based approach of Leaf color chart (LCC) based nitrogen scheduling would synchronize crop demand and soil supply. LCC reflectsleaf N concentration. It is an simple, easy handling cost effective tool to manage nitrogen top dressings in rice.
