Yield and Economics of Hybrid Maize (Zea mays L.) under Integrated Nutrient Management Practices in Odisha, India

Abstract

A field experiment was carried out at Regional Research and Technology Transfer Station, Odisha University of Agriculture and Technology, Semiliguda of Koraput district under Eastern Ghat High Land zone of Odisha in acidic soil during two consecutive kharif seasons of 2016 and 2017 to study the response of integrated nutrient management on yield and economics of hybrid maize. The experiment was laid out in randomized block design with three replications consisting of twelve treatments. The present investigation revealed that application of soil test fertilizer dose with green manure (cowpea), FYM @ 5 t ha-1 and biofertilizer (Azotobacter + Azospirillum + PSB @ 4 kg ha-1 each) resulted significantly higher seed yield of 7384 kg ha-1 with a net monetary return of Rs. 50838 ha-1 and benefit cost ratio of 1.97.
