Response of wheat (Triticum aestivum L.) varieties to integrated nutrient management for grain yield & its attributes

Abstract

Response of wheat (Triticum aestivum L.) varieties to integrated nutrient management for grain yield & its attributes was studied in a field experiment at the Department of Agriculture, Maharishi Markandeshwar (Deemed to be) University, Mullana, Ambala, Haryana, during the winter (Rabi) season of 2021–2022. The soil in the experimental field used to have an electrical conductivity of 0.89 d/Sm, was sandy loam, well-drained, alkaline (pH 7.23), low in nitrogen, medium in phosphorus, and high in potassium. Seven treatments were evaluated in a randomised block design (RBD) with three replications, as well as the control and the recommended dose of fertilisers (RDF) for wheat (Varieties “DBW 222”, “HD 2967” and “PBW 723”) with varying application periods. The T7 treatment, which included 50% of the appropriate N, P, and K dose through chemical fertilisers and 50% of the recommended vermicompost dose, had the highest grain production, biological yield, and harvest index readings. This treatment was shown to be statistically comparable to T6 (50% approved FYM dose and 50% recommended dose of chemical fertilisers for N, P, and K). Characters with yield attribution had a substantially larger yield in T7 treatment.
