Effect of Integrated Nutrient Management on Fertilizer Use Efficiency in Wheat (Triticum aestivum L.) under Irrigated Condition

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.
