Effect of Integrated Nitrogen Management on Growth and Yield Attributes of wheat (Triticum aestivum L.) under Late Sown Condition

Abstract

A field experiment conducted during the rabi season 2024–25 at the Agronomy Research Farm, R.S.M. (P.G.) College, Dhampur (Bijnor), Uttar Pradesh, to evaluate the impact of integrated nitrogen management on wheat growth and yield attributes. The study included seven treatments, control (T1), 100% recommended dose of fertilizer RDF: 150-60-60 NPK kg ha⁻¹ (T2), 80% RDN through urea + 20 RDN through poultry manure (T3), 80% RDN through urea + 20 RDN through vermicompost (T4), 80% RDN through urea + 20 RDN through farmyard manure (T5), 80% RDN through urea + 20 RDN through mustard cake (T6), 80% RDN through urea + 20 RDN through goat manure (T7) arranged in a randomized block design with three replications. The results revealed that maximum plant height, number of leaves, fresh weight and dry weight of plant were observed in 80% RDN through urea + 20 RDN through farmyard manure (T5). The yield attributes i.e. spike length, awns length, filled grain and unfilled grain maximum found in 80% RDN through urea + 20 RDN through farmyard manure (T5). These findings suggest that integrating FYM with chemical nitrogen not only improves crop performance and productivity but also contributes to better soil health, making it a sustainable nutrient management practice for wheat cultivation.
