Among various pulse crops cowpea [Vigna unguiculata (L.) Walp.] is an important food legume and grown over an area of 0.5 million ha, it is adapted to wide range of soils, rainfall situations and fits as an crop in multiple and intercropping systems. The present investigation was carried on Rabi-2022 cv. Pusa Komal at the Horticultural Research Farm, Sardar Patel University, Balaghat (M.P.). The experiment was laid out in a Randomized Block Design (RBD) with eight treatments in three replications. The applications of organic and inorganic nutrient applications like T1- Control, T2-100% RDF, T3- 75% RDF + 25% FYM, T4-75% RDF + 25% Vermicompost, T5-50% RDF + 50% FYM, T6-50% RDF + 50% Vermicompost, T7-25% RDF + 75% FYM, T8-25% RDF + 75% Vermicompost was used for the experiment. At the growth stage of 25, 50 and 75 DAS of crop, the maximum plant height was observed under the treatment the treatment T2 (100 % RDF), followed by the treatment T3 (75% RDF + 25% FYM) and T5 (50% RDF + 50% FYM), at the growth stage of 25, 50 & 75 DAS of crop, the maximum number of primary branches/plant was observed under the treatment T2 (100 % RDF), followed by the treatment T3 (75% RDF + 25% FYM) and T5 (50% RDF + 50% FYM), while the minimum plant height and number of primary branches/plant at 25, 50 & 75 DAS was observed under the treatment T1 (Control), the early days for 1st flowering in cowpea was observed under the treatment T2 (100 % RDF), followed by the treatment T3 (75% RDF + 25% FYM) and T5 (50% RDF + 50% FYM), the early days for 1st Fruiting in cowpea was observed under the treatment T2 (100 % RDF), followed by the treatment T3 (75% RDF + 25% FYM) and T5 (50% RDF + 50% FYM), the Days to maturity of Fruits in cowpea was observed under the treatment T2 (100 % RDF), followed by the treatment T3 (75% RDF + 25% FYM) and T5 (50% RDF + 50% FYM), the maximum total Number of pods per plant at maturity and pod length was observed under the treatment T2 (100 % RDF), followed by the treatment T3 (75% RDF + 25% FYM), the maximum pod diameter was observed under the treatment T2 (100 % RDF), followed by the treatment T7 (25% RDF + 75% FYM) and T5 (50% RDF + 50% FYM), the maximum seed yield per plant, seed yield per plot (kg) and seed yield (q/ha) was observed under the treatment T2 (100 % RDF), followed by the treatment T3 (75% RDF + 25% FYM) and T5 (50% RDF + 50% FYM), the maximum Seed Weight (g) was observed under the treatment T8 (25% RDF + 75% Vermicompost), followed by the treatment T7 (25% RDF + 75% FYM) and T6 (50% RDF + 50% Vermicompost), the maximum gross return was found in the treatment T2 because of the nutrient application is 100% recommended dose (100% RDF) they are small in quantity and less in price compare to other manures, the average net return or the maximum net profit was obtained under treatment T2 (100% RDF) which was closely followed by treatment T3 (75% RDF + 25% FYM), while the minimum was found in all the treatments under the treatment T1 (Control). Limited focus on integrated approaches, optimizing nutrient ratios, lack of long-term studies, and socio-economic constraints are key challenges.

From above experimental findings on Effect of Integrated Nutrient Management on it is concluded that treatment T1, 100% RDF performed best for yield, quality parameters and economics in Cow pea.
