Evaluating nitrogen management strategies improves crop yield in wheat, suggesting effective fertilization methods.
Wheat (Triticum aestivum) is one of the most important staple food crops in India, ranking second after rice in terms of area and production. It plays a crucial role in ensuring food security for millions of Indians. The experiment was conducted during 2022-23 at the soil research farm of CCS Haryana Agricultural University, Hisar. Applying 130% of RDN increased the wheat crop yield to 52.09 q/ha, while the control recorded a minimum of 25 q/ha. It also enhanced the available nitrogen in the soil. Wheat grain and straw yields significantly increased with higher nitrogen doses, except at 145% of high nitrogen doses, where the wheat grain yield decreased. In all treatments with high doses of N and the recommended dose of fertiliser (RDF), soil pH and electrical conductivity showed no statistically significant differences.
