Abstract
The experiment included four levels of NAA, 10, 20, 30, and 40 ppm, and four levels of GA3, 10, 20, 30, and 40 ppm, administered topically and evaluated in comparison to a control (water spray). The measurements of several parameters, such as fruit set, fruit size, fruit volume, fruit weight of 100 fruits, fruit yield per plant, and fruit yield per hectare, were made. According to the experiment, GA3 at 40 ppm enhanced fruit set, size, weight, and volume of the fruits, yield. Combining NAA+GA3 proved effective in improving the fruit set, fruit size, yield, and quality characteristics of phalsa fruits. For higher returns in the agro-climatic conditions of Central Uttar Pradesh, phalsa growers may be advised to apply these growth regulators.
