Abstract
The experiment entitled “Integrated nutrient management in vegetable cowpea (Vigna unguiculata L.)” was carried out during summer season of 2018 at the Horticulture Farm, College of Horticulture, Sardarkrushinagar Dantiwada Agricultural University, Jagudan, Gujarat. The experiment was laid out in randomized block design with three replications. Total fourteen treatments were evaluated in the present study viz., T1: 100% RDF (25: 50: 00: NPK kg/ha); T2: 100% RDN through urea; T3: 75% RDN through FYM + 25% N through urea; T4: 50% RDN through FYM + 50% N through urea; T5: 75% RDN through vermicompost + 25% N through urea; T6: 50% RDN through vermicompost + 50% N through urea; T7: 75% RDN through neem cake + 25% N through urea; T8: 50% RDN through neem cake + 50% N through urea; T9: T3+ Rhizobium @ 10 ml / kg + PSB @ 2.5 lit / ha; T10: T4+ Rhizobium @ 10 ml / kg + PSB @ 2.5 lit /ha; T11: T5+ Rhizobium @ 10 ml / kg + PSB @ 2.5 lit /ha; T12: T6+ Rhizobium @ 10 ml / kg+ PSB @ 2.5 lit /ha; T13: T7+ Rhizobium @ 10 ml / kg + PSB @ 2.5 lit /ha; T14: T8+ Rhizobium @ 10 ml / kg + PSB @ 2.5 lit /ha. Among various treatments, treatment T11 (T5+ Rhizobium @ 10 ml / kg + PSB @ 2.5 lit /ha) was significantly superior over all other treatments with respect to growth and yield parameters. The growth parameters viz., plant height at 30 DAS (23.72 cm) and 60 DAS (60.67 cm), number of branches (9.07) at 60 DAS and nodules per plant (19.87) and yield parameters viz., number of green pods per plant (58.65), yield per plant (117.24 g/plant), yield per plot (2.30 kg/plot) and yield per hectare (85.06 q/ha) were recorded maximum with treatment T11.
