Study the effect of integrated nutrient management on nutrients uptake and soil health of rice (Oryza sativa L.) crop

Abstract

An experiment entitled “Studies on integrated nutrient management for sustainable production, nutrients uptake and soil health in rice (Oryza sativa L.) Crop” was conducted at Crop Research Farm Nawabganj, College of Agriculture, Chandra Shekhar Azad University of Agriculture & Technology Kanpur (U.P.) in Kharif season for two years (2014 and 2015). The experiment was conducted in Randomized Block Design (RBD) with four replications and nine treatments combination. Maximum total nutrients uptake (N, P, K, S, Zn and Mn) by rice 84.92, 6.73, 61.97, 21.22 kg ha-1 324.73 and 765.49 g ha-1,respectively were observed in the treatment receiving 75 % NPK (RDF)+FYM @ 5 t ha-1+PSB+S40 kg ha-1+Zn5 kg ha-1+Mn8 kg ha-1 (T9) and lowest values recorded at control (T1).The conjunctive use of organic manure and fertilizers along with bio fertilizers and micronutrients gave the highest availability of N, P, K, S, Zn and Mn at post- harvest soil of rice as compared to other treatment combinations.
