Effect of Integrated Nutrient Management on Nutrient Content and Uptake of Blackgram

Abstract:
A field experiment was conducted during the kharif season of 2024 at the Agronomy Instructional Farm, Rajasthan College of Agriculture, Udaipur, to evaluate the effect of integrated nutrient management (INM) on nutrient content and uptake in blackgram (Vigna mungo L.). The experiment followed a factorial randomized block design with 18 treatment combinations involving three fertility levels (100% RDF, 100% RDF + Zn, 100% RDF + Zn + Mo), three vermicompost levels (0, 1, and 2 t ha⁻¹), and two biofertilizer levels (control and NPK liquid consortia). Results revealed that the combined application of 100% RDF + Zn + Mo + vermicompost 2 t ha⁻¹ + NPK consortia significantly enhanced nitrogen, phosphorus and potassium content in seed and improved their uptake in both seed and haulm. The treatment also recorded the highest total N, P, and K uptake by seed and haulm.
