Impact of Integrated Nutrient Management on Yield in Wheat (Triticum aestivum L.) in Agra Region, India

Abstract

The present research entitled “Impact of Integrated Nutrient Management on Yield in Wheat (Triticum aestivum L.) in Agra Region” was conducted during the Rabi season of 2024–2025 at the Agricultural Research Farm, R.B. (PG) College, Agra, Uttar Pradesh. The objective of the study was to evaluate the impact of various combinations of inorganic and organic nutrient sources on growth and yield in wheat. The experiment was laid out in a randomized block design (RBD) comprising ten treatments with three replications. Treatments included different combinations of recommended doses of fertilizers (RDF) with farmyard manure (FYM), vermicompost, and poultry manure. The results reveal that integrated nutrient management (INM) practices significantly influenced growth and yield parameters. Among the treatments, T₁ (100% RDF) recorded the highest grain yield (68.610 q/ha), while T₅ (25% RDF + 75% RDN through 1/3 FYM + 1/3 vermicompost + 1/3 poultry manure) achieved the maximum biological yield (101.943 q/ha-1) and straw yield (56.220 q/ha-1), along with superior performance in plant height and number of tiller per plant. The highest harvest index (58.150%) was observed in T₇ (50% RDF + 50% RDN through vermicompost), indicating efficient assimilates partitioning. The study concludes that integrated nutrient management, particularly treatments T₅ and T₇, effectively enhances wheat productivity and sustainability under the agro-climatic conditions of the Agra region.
