Abstract:
A field trial was conducted at agronomy farm, S.K.N. Agriculture University, Jobner during kharif season of 2019 to study the response of cowpea [Vigna unguiculata (L.) Walp] to integrated nutrient management. The experiment comprised of 12 treatments involving control, RDF (20:40), FYM, Poultry Manure and their respective combinations including biofertilizers which was laid out in randomized block design with four replications. Results revealed that the magnitude of most of physiological parameters was increased under combined application of T₁₂- 50% RDF + PM @ 2 t/ha + Rhizobium + PSB followed by T₁₁- 50% RDF + FYM @ 4 t/ha + Rhizobium + PSB, T₁₀- 50% RDF + PM @ 2 t/ha + PSB, T₉- 50% RDF + FYM @ 4 t/ha + PSB, T₈- 50% RDF + PM @ 2 t/ha + Rhizobium, T₇-50% RDF + FYM @ 4 t/ha + Rhizobium, T₆- 50% RDF + PM @ 2 t/ha, T₅- 50% RDF + FYM @ 4 t/ha, T₄-PM @ 4 t/ha, T₃- FYM @ 8 t/ha and T₂- 100% RDF (20:40) and significantly superior to rest of the treatments. T₁₂ treatment recorded higher CGR, RGR, Leaf area index and Chlorophyll content remained at par on treatment T₆, T₇, T₈, T₉, T₁₀ and T₁₁.
