Abstract:
An experiment was conducted during 2019-20 and 2020-21 at Research Farm of Centre of Excellence on Protected Cultivation and Precision Farming under net house, College of Agriculture, IGKV, Raipur to study the response of various plant growth regulators at different concentrations namely, NAA (100, 150, 200 ppm), GA₃ (100, 150, 200 ppm) and BA (100, 150, 200 ppm) on flowering, fruit setting, fruiting and maturity of papaya cv. Red Lady. As far as the days to first flowering and days to first fruiting is concerned the treatment of gibberellic acid 200 ppm treated plants comes early flowering (71.9 days) and fruiting (73.37 days) as compared to other treatments, while the maximum days to first flowering (83.04 days) and fruiting (87.77 days) were observed under the treatment T₀ (control). Similarly the same treatment (T₆) was taken maximum fruit set per cent (83.99) lowest time for flowering to maturity (189.38 days) as compared to other treatments. Thus, a spray of gibberellic acid 200 ppm is best for early flowering, fruiting, days to flowering to maturity and maximum fruit setting percentage of papaya.
