Influence of integrated nutrient management practices on dry matter production, yield and NPK uptake of transplanted rice (Oryza sativa)
Journal Title: Journal of Applied and Natural Science - Year 2016, Vol 8, Issue 2
Abstract
A field investigation was carried out during Rabi season (Pishanam rice) of 2012-2013 at wetland of Central Farm, Agricultural College and Research Institute, TNAU, Killikulam, to study the effect of integrated nutrient management practices on dry matter production, yield and NPK uptake of transplanted rice. The treatments were laid out in a Randomized Block Design and replicated thrice using the rice variety ADT(R) 45. Among the different integrated nutrient management practices, application of GLM @ 6.25 t ha-1 + Azophosmet + 100 % NPK registered significantly the highest (P<0.01) dry matter production at all the stages (Active tillering; 1690, flowering; 9100 and harvest;14490 kg ha-1). The grain yield was increased, when GLM was integrated with 100 % NPK application (6030 kg ha-1). The grain yield was further increased, when Azophosmet was applied through seed and soil application along with GLM and 100 % NPK (6617 kg ha-1). However, it was on par with application of FYM + Azophosmet + 100 % NPK. The same trend was noticed in straw yield also. The uptake of N, P and K nutrients by rice crop at har-vest stages (95.6, 37.7 and 118 kg ha-1) of crop growth was remarkably increased by the application of GLM + Azophosmet + 100 % NPK. Among the various nutrient management practices, application of GLM + Azophosmet + 100 % NPK registered superior growth indicators due to the effective utilization of various nutrients and subsequent accumulation of more assimilates which inturn led to improved vegetative growth and higher yield of transplanted rice.
