Abstract:
Present investigation was framed with Sixty (60) treatments consisting of 10 PGR’s level, P0 (distilled water), GA₃ (100 ppm, 150 ppm and 200 ppm), NAA (100 ppm, 150 ppm and 200 ppm), IAA (30 ppm, 60 ppm and 90 ppm), 2 Stage of plant for spraying of PGRs, S1 (4 leaf stage), S2 (4 leaf stage + Flower initiation) and 3 pickings of fruits, H1 (3 Pickings of fresh fruits + rest fruits left for seed production), H2 (6 Pickings of fresh fruits + rest fruits left for seed production), H3 (No pickings of fresh fruits + all fruits left for seed production) were laid out in randomized block design (factorial) with three replications to find out the most suitable PGR’s level and stage of plant for spray as well as fresh fruit pickings to increase the seed yield of okra. It was observed that the different levels of treatments affected the growth and yield attributes of the crops. Among the treatments, P2S1H1 treatment was recorded maximum plant height (119.50 cm), days taken to 50% flowering (38.17 days), days taken to 1^st harvest (25.83 days), number of fruits/ plant (15.25), number of seeds per pod (54.75), 100 seed weight (6.60), Seed yield/ plant (32.64g), seed yield/ha (12.95). Therefore, it may be concluded that P2S1H1 treatment was superior among all treatments. Similar trend was also observed under the treatment P1S1H1.
