A field trial was conducted at the agronomy farm, S.K.N. Agriculture University, Jobner during the kharif season of 2019 to study the response of cowpea [Vigna unguiculata (L.) Walp] to integrated nutrient management. The experiment comprised 12 treatments involving control, RDF (20:40), FYM, Poultry Manure, and their respective combinations, including biofertilizers, which were laid out in a randomized block design with four replications. Results revealed that the magnitude of protein content was recorded higher under the combined application of 50% RDF + PM @ 2 t/ha + Rhizobium + PSB (T12) and remained at par on treatment T11, T10, and T9. The application of T12 (50% RDF + PM @ 2 t/ha + Rhizobium + PSB) gave significantly higher net returns over T1 to T4 treatments. However, it remained at par with T11, T10, T9, T8, T7, T6, and T5 treatments.
