Abstract
A field experiment was conducted to study the effect of integrated nutrient management on growth, yield and quality of okra (Abelmoschusesculentus(L). Moench.)Cv. ArkaAnamikaunder drip irrigation at College of Horticulture, UHS Campus, GKVK Post, Bengaluru during kharif-2016. The results revealed that combined application of 50% RDF +25% N through vermicompost + 25% N through neemcake + panchagavya + 5% cow urine at 30 and 40 DAS. (T9) recorded significantly higher plant height (132.17 cm), number of leaves (28.30), stem girth (4.76 cm), number of nodes per plant (15.38), number of fruits per plant (21.17), fruit length (22.55 cm), fruit girth (6.50 cm) fruit weight (28.34 g), fruit yield per plant (460.22 g), fruit yield per plot (19.32 kg), total yield per hectare (17.03 t/ha), dry weight of plant (79.27g), maximum total uptake of nitrogen (58.92 kg/ha), phosphorus (17.31 kg/ha), and potassium (89.16 kg/ha), highest net returns (Rs. 250425.8), benefit cost ratio of 3.77:1 and residual soil nitrogen (313.60 kg/ha),phosphorus (28.60 kg/ha) and potassium (188.00 kg/ha) content followed by plants provided with50% RDF + 50% nitrogen through neemcake + 5% cow urine at 30 and 40 DAS (T8)recoded the highest yield (14.72t ha-1), net returns (Rs. 213717.32) and benefit cost ratio (3.64:1) during the crop season. Based on the growth, yield, quality and B: C ratio. Application of _ 50 % RDF + 25% nitrogen through vermicompost + 25% N through neemcake + panchagavya + 5% cow urine at 30 and 40 DAS (T9) was found optimum for cultivation of okra crop under drip irrigation.
