Effect of different source of nutrients on yield and economics of cowpea [Vigna unguiculata (L.) Walp]

Abstract

A field experiment was conducted at Research farm, Vivekananda Global University, Jaipur (Rajasthan) during Kharif¸ 2024 on loamy sand soil. The experiment comprising nine treatments of different source of nutrients (RDF 100% (20 kg N ha-1 and 40 kg P ha-1), FYM @ 5.0 t/ha, FYM @ 2.5 t/ha + NPK 50% RDF, Neem cake @ 1.0 t/ha, Neem cake @ 0.5 t/ha + NPK 50% RDF, Vermicompost @ 2.0 t/ha, Vermicompost @ 0.5 t/ha + NPK 50% RDF, Poultry manure @ 1.0 t/ha and Poultry manure @ 0.5 t/ha + NPK 50% RDF) was laid out in Randomized Block Design and replicated thrice. Results showed that application of T9 (Poultry manure @ 0.5 t/ha + NPK 50% RDF) significantly increased the grain and straw yield of 909 and 2213 kg/ha, respectively. Remaining at par with T5 (Neem cake @ 0.5 q/ha + NPK 50% RDF) and T3 (FYM @ 2.5 t/ha + NPK 50% RDF). Poultry manure @ 0.5 t/ha + NPK 50% RDF also fetched highest net returns (46267 Rs./ha) with the highest B: C ratio (3.72).
