Effect of integrated nutrient management on sweet corn–potato cropping system: Productivity, economic yield and soil nutrient balance

Abstract

The study was conducted to estimate the productivity, economic yield and soil nutrient balance of integrated nutrient management in sweet corn-potato cropping sequence was conducted during kharif and rabi season of 2014-15 to 2015-16 at Instructional Research Farm, Central Campus, Post Graduate Institute, Mahatma Phule Krishi Vidyapeeth, Rahuri. The performance of sweet corn–potato cropping sequence was assessed in terms of residual fertility status at the end of two years crop sequence. The treatment T1-100% GRDF to preceding crop sweet corn during kharif season registered maximum net gain of nitrogen, phosphorus and potassium (+49.19, +6.54 and +80.74 kg ha-1) at the end of two years experimentation.
