Effect of Inorganic and Bio-Fertilizers on Vegetative Growth and Yield of Okra (Abelmoschus esculentus L. Moench) cv. Arka Anamika

A field experiment was conducted to investigate the effect of inorganic and bio-fertilizers on vegetative growth and yield attributes of okra cv. Arka Anamika. Three levels of inorganic fertilizers (NPK) viz. N1 (N2O 50 kg, P2O5 30 kg, K2O 20 kg), N2 (N2O 70 kg, P2O5 50 kg, K2O 40 kg) and N3 (N2O 90 kg, P2O5 70 kg, K2O 60 kg), and three levels of bio-fertilizers i.e. B1 (Azotobactor 7.5 kg/ha), B2 (PSB 7.5 kg/ha) and B3 (Rhizobium 7.5 kg/ha) were tested in present experiment. Results revealed that vegetative growth parameters (plant height, number of branches /plant, number of leaves/plant, plant spread, length of internodes) and yield parameters (number of fruits/ branch, number of fruits/plant, diameter of fruit, fresh weight of fruit and fruit yield) were recorded maximum at N3 level of inorganic fertilizers and B1 (Azotobactor). However, the bio-fertilizers significantly increased the above parameters as compared to control and other N P K levels.
