Response of integrated nutrient management on quality and economics of maize (Zea mays) crop

Abstract

A field experiment was conducted at field no. 6 Student’s Instructural Farm at Chandra Shekhar Azad University of Agriculture and Technology, Kanpur during the Kharif season 2017 to find out integrated nutrient management effect on maize with ten treatments i.e. T1 (125% RDN), T2 (100% RDN), T3 (100% RDN + 25% N FYM), T4 (100% RDN + 25% N FYM + S30), T5 (100% RDN + 25% N FYM + S30 + Zn5), T6 (75% RDN), T7 (75% RDN + 25% N FYM), T8 (75% RDN + 25% N FYM + S30), T9 (75% RDN + FYM + S30 + Zn5), T10 (Control) in RBD with 3 replications. Maize variety Azad Uttam was taken for study. The result showed highest protein content (8.99%) in treatment T5 and lowest protein content (7.62%) in treatment T1. Economically the Net returns range is 20687 to 43306 Rs/ha and benefit cost ratio range 1.84 to 2.16 respectively. The treatment combination T5 (100% RDN + 25% N FYM + S30 + Zn5) gave the best result in terms of crop quality and economics of crop.
