Effect of Eco-Friendly Modified Urea Materials on Growth and Yield of Aerobic and Puddled Rice in Semi-Aerid Tropical Region of Sutheren India

A field experiment was conducted during kharif season of 2013 to find out the effect of ecofriendly modified urea materialsunder aerobic and puddled rice cultivation on growth andyield of rice at College Farm, PJTSAU. The results revealed with application of natural nitrification inhibitors (NNI)significantly improved plant growth parameters and inturn grain yield over prilled urea (PU)in both methods of rice cultivation.Puddled rice significantly registered higher leaf area index and drymatter accumulation than aerobic rice at different growth stages with application of NNI as compared with PU.27.5% higher grain yield was recorded in cultivation of puddled rice (5.04 t ha -1 ) than aerobic rice cultivation (4.51 t ha -1 ). Significantly grain yield increased by26, 38 and 25% with the application of KCU, VCU and NCCU, respectively than PUin both methods of rice cultivation. Theeco-friendly modified urea materials (NNI)used in present study was equally good and one can choose based upon availability of farmersunder both methods of aerobic and puddled condition.
