Evaluation of biofertilizers and inorganic fertilizers on vegetative growth and yield of okra (Abelomoschus esculentus L. Moench)

Abstract

An experiment was conducted at the farm of S. Boota Singh, village Midda, Distt. Shri Muktsar Sahib, Punjab, India, during the year 2018 for the evaluation of biofertilizers and inorganic fertilizers on vegetative growth and yield of okra (Abelomoschus esculentus L. Moench). The treatments were, T1 - Azotobacter + 50% N + 100% P & K, T2 - Azotobacter + 75% N + 100% P & K, T3 - PSB + 50% P + 100% N & K, T4 - PSB + 75% P + 100% N & K, T5 – Control. The effect of these factors on plant height, stem girth, number of leaves per plant, number of branches per plant, number of flowers, number of fruits per plant, yield per picking and total yield was observed. Out of these treatments, T1 has performed better in one parameter which is plant height (107.2) cm and T2 performed better in all remaining parameters number of branches (5.2), number of leaves (34.4), stem girth 5.12 number of flowers per plant 16.6, number of pods per plant (12.6), yield per picking and total yield (52.76) qtl/acre It is concluded from the experiment that higher yield can be obtained T2 (Azotobacter + 75% N + 100% P & K).
