Effect of integrated nutrient management on economics of cowpea [Vigna unguiculata (L.) Walp.]

Abstract

A field experiment was conducted at Research Farm of Suresh Gyan Vihar University, Jaipur (Rajasthan) during kharif 2023 on sandy loam soil, consisting nine treatments viz. control (T0), 100% RDF (T1), 75% RDF + biofertilizer (T2), FYM @ 5 t ha-1 (T3), FYM @ 2.5 t ha-1 + 50% RDF (T4), vermicompost @ 2 t ha-1 + 50% RDF (T5), vermicompost @ 1 t ha-1 + 50% RDF (T6), FYM @ 75% + biofertilizer (T7) and vermicompost @ 75% + biofertilizer (T8) which were laid out in a randomized block design with three replications. Variety RC-19 was used for experiment. Results clearly showed that highest net returns of ₹91916 ha-1 and B:C of 2.86 was significantly higher registered due to application of vermicompost @ 1 t ha-1 + 50% RDF (T6) which remained at par with vermicompost @ 75% + biofertilizer (T8) but significantly higher over control.
