Abstract:

In crop nutrient management, crop yields can be increased by minimizing nutrient losses in the environment by managing nutrient supply to the root zone within a reasonable range which realizes the biological need of crops to match N requirement high-yielding crop, and controls nutrient losses. Minimal Nutrient supply and nutrient requirements in high yielding cropping systems must be matched in quantity and synchronized in time and space. To achieves this goal, to identify the optimum and cost effective nutrient management practices in different crop establishment methods, a study was conducted during 2015-16 and 2016-17, experiment was laid out in split plot design with 3 main plots {M1:Mechanical transplanting method (all the principles as per SRI), M2: Direct Seeding with SRI principles saturation method of water management weeding with cono weeder and fertilizer management and M3:Normal transplanting (20 x 15 cm with flood water management, 3-4 seedlings transplanted at 25 to30 days old seedlings and 5 subplots (S1- 100% RD, S2-75% inorganic + 25% organic equivalent N dose, S3-150% RDF, S4-LCC based N application and S5-Location specific fertilizer management. Among the crop establishments methods, use of mechanical transplanting and adopting all the principles as per SRI, performed excellently by registering higher yield attributes and grain yield of 5910 and 5767 kg ha-1 during Kharif 2015 and 2016, respectively. While comparing the method of nutrient management practices LCC based N application registered higher grain yield of 6430 and 6635 kg ha-1 during Kharif 2015 and 2016, respectively, which is also economically feasible besides higher net return due to reduce the cost of production particularly in edging out higher inorganic fertilizers without affecting the grain yield.
