Effect of FYM and Fertilizers Nutrition on Production Potential, Nutrients Uptake and Soil Properties under Rice-Wheat Cropping SystemSoil Properties under Rice-Wheat Cropping System

Afield experiment was conducted during the Kharif and Rabi seasons of 2001-2005 in regular crop sequence at Crop Research Station, Nawabganj, CSAUniversity of Agriculture & Technology, Kanpur in order to find out the effect of farm yard manure (FYM) and NPK levels in rice-wheat -1-1cropping system. One level of FYM (10 t ha) and one level of N (120 kg ha),three levels of P(0, 30, -1-160 kg ha), four levels of K (0, 30, 60, 90 kg ha) were tested. The grain yield of rice and wheat crops -1-1were increased at levels of FYM (10 t ha) and NPK (120, 60, 60 kg h a). The application of FYM with 1120 kg N, 60 kg POand 60 kg KO ha-gave significantly highest yield of rice and wheat crops. The 252application of NPK fertilizers with FYM were found increased in their uptake. The application of NPK fertilizers with FYM was found improvements in physio-chemical properties of soil like soil ph, organic carbon and available NPK
