Effect of integrated nutrient management on growth, yield and quality of cowpea

The present investigation entitled "Effect of integrated nutrient management on growth, yield and quality of cowpea" conducted at University Research Farm, GHRU, Saikheda in Rabi Season 2023. The trial was conducted in nine treatments with three replication and analyzed in Randomized Block Design and the variety was used in trial is Pusa Komal for observed the growth, yield and economics of the cowpea. The treatment details T1 - FYM @ 20 t/ha + 25% RDF of NPK/ha (15:20:18.75 kg), T2 - FYM @ 20 t/ha + 50% RDF of NPK/ha (30:40:37.5 kg), T3 - FYM @ 20 t/ha + 100% RDF of NPK/ha (60:80:75 kg), T4 -Neem cake @ 5 q/ha + 25% RDF of NPK/ha (15:20:18.75 kg), T 5 - Neem cake @ 5q/ha + 50% RDF of NPK/ha (30:40:37.5 kg), T6 - Neem cake @ 5 q/ha + 100% RDF of NPK/ha (60:80:75 kg), T7 - Vermicompost 5 t/ha + 25% RDF of NPK/ha (15:20:18.75 kg), T8 - Vermicompost 5 t/ha + 50% RDF of NPK/ha (30:40:37.5 kg) and T9 - Vermicompost 5 t/ha + 100% RDF of NPK/ha (60:80:75 kg). The observation was recorded and plant i.e. Plant height at 45 and 75 DAS, Number of branches/plant at 45 and 75 DAS, Average Diameter of pod, Average weight per pod, Average fruit yield per plant, Fruit yield per plot and Fruit yield per ha. The result revealed that the maximum Plant height at 45 and 75 DAS (43.10 and 108.60 cm), Number of branches/plant at 45 and 75 DAS (9.22 and 20.38), Average Diameter of pod (1.39 cm), Average weight per pod (20.92 g), Average fruit yield per plant (0.37 kg), Fruit yield per plot (15.63 kg) and Fruit yield per ha (275.68 q/ha), while the minimum was observed under T1.
