Abstract

A field experiment was conducted during 2017-18 and 2018-19 at Agronomy Research Farm, CCS HAU Hisar to study the effect of integrated nutrient management on fertilizer use efficiency of wheat. The experiment was laid out in randomized block design with three replications and ten treatments. During both the years, the significantly highest agronomical nitrogen use efficiency, apparent recovery efficiency of nitrogen, utilization efficiency of nitrogen, economic nutrient use efficiency and nutrient removal ratio of wheat were recorded with application of 100% RDN. Application of 25% RDN + 75% N through FYM was noted to have the significantly higher physiological nitrogen use efficiency and nutrient efficiency ratio, being at par with application of 25% RDN + 75% N through vermicompost. The highest nutrient increment efficiency of nitrogen and lowest agro-physiological nitrogen use efficiency was observed with application of 100% RDN + 25% N through vermicompost.
