Abstract:
A field experiment was conducted at department of horticulture, VNMKV, Parbhani during 2021-2022 year to study the effect of different growth regulators like 28- Homobrassinolide, CPPU, GA₃ and Humic Acid and Bio-mix on yield of sapota fruits and physio-chemical parameters of sapota cv. Kalipatti. The different plant growth regulators i.e., 28-Homobrassionoids @ 0.50 ppm and @ 0.75 ppm, CPPU @ 4 ppm and 6 ppm, Humic Acid @ 1% and 2%, GA₃ @ 50 ppm and 100 ppm and Bio-mix @ 50 ml, 75 ml and 100 ml/plant were applied through foliar spray. The obtained results shows that the fruit yield parameters in terms of number of fruits harvested per plant, fruit yield (kg) and yield of fruits per hectare (q) was recorded maximum (1812.19, 165.60 kg and 16.56 q respectively) in plants which were treated by GA₃ @ 100 ppm. The CPPU treatments shown significant effect on physio-chemical parameters of sapota fruits. The highest TSS (24.22 ⁰Brix), high reducing sugar (11.46% ), highest non-reducing sugar (9.47%), high ascorbic acid (25.17 mg/100 ml) and lowest Acidity (0.0321%) was observed in treatment of CPPU @ 6 ppm as compared to control.
