Abstract: India is the largest producer of pulses. Black gram (urd) is one of the most important pulse crops as it has the potential to contribute on a large scale to the pulse production in India. Regardless of higher and sustainable crop productivity, manure and fertilizer maintenance in black gram crop production is also extremely desirable. The aim of present investigation was to study the “Effect of Integrated plant nutrient supply on NPK content and uptake by seed and straw in black gram” conducted in Kharif season at the research farm of Amar Singh Post Graduate College, Lakhaoti, Bulandshahar, U.P. Study concluded that Treatment T₈ (<em>Azoto + Rhizobium</em> + PSB + FYM + Chem.) resulted in significant increase in N, P, and K content as well as their uptake by urd crop. This was closely followed by treatments T₃ and T₇ in both the years. Therefore, for maximum productivity of urd and inherent fertility of soil for future period, the importance of integrated plant nutrient system (IPNS) in urd has raised.
