Energy studies of sweet corn-potato cropping sequence under integrated nutrient management

Abstract

The present investigation was conducted for kharif and rabi season on sweet corn-potato cropping system for two consecutive years (2014-15 and 2015-16) in a clayey in texture soil at the Post Graduate Institute Research Farm, M.P.K.V., Rahuri (Maharashtra) India. To evaluate the energy studies of sweet corn-potato cropping sequence under integrated nutrient management. The results revealed that significant enhancement in the energy output (457541, 468162 and 462852 MJ ha--1), energy balance (385966, 396152 and 391059 MJ ha-1), energy balance per unit input (5.39, 5.50 and 5.45 MJ ha-1) and energy use efficiency (6.39, 6.50 and 6.45 MJ ha-1) of the sweet corn-potato cropping system with the application of treatment T7-125% RDN + 25% N through vermicompost during the period of study. Thus, use of organic sources vermicompost significantly improved the Energy output, energy balance per unit input and energy use efficiency of the sweet corn-potato cropping system.
