Effect of integrated nutrient management on growth, yield attributes and yield of black wheat (Triticum aestivum L.) under late sown condition

Abstract

Wheat (Triticum aestivum L.) cultivation under late-sown conditions faces challenges that affect growth and yield. This study aimed to evaluate the efficacy of integrated nutrient management (INM) on the growth, yield attributes and yield of black wheat. A field experiment was conducted during the Rabi season 2022-23 at Maharishi Markandeshwar (Deemed to be University), the experiment utilized a randomized complete randomized block design with eight treatments, including various combinations of urea, vermicompost, Hairamine spray and Azotobacter. Among these, treatments T6 (100% RDN through urea + Hairamine spray) emerged as the most effective, showcasing superior plant height, increased dry matter accumulation, prolific tillering and robust yield attributes. Notably, treatment T6 exhibited the highest grain yield at 40.92 q/ha, surpassing other treatments significantly. These findings underscored the potential of tailored INM strategies, particularly T6, in optimizing black wheat productivity under challenging late-sown conditions, thereby supporting sustainable agricultural practices and food security.
