Abstract
An experiment was carried out in the departmental field of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during February to May 2021 on bitter gourd (Momordica charantia L.) to find out the best treatments of plant growth regulators for better growth and yield in bitter gourd. The experiment include growth regulators like GA3 and NAA with different ppm. Nine treatments were made and replicated thrice in randomized block design. Application of plant growth regulators was done as per the treatment allocation at four leaf stage. The experimental results revealed that treatment 25 ppm GA3 was found most effective in terms of vine length and results maximum at 20,40,60 and at harvest, and days to first appearance of male flowers whereas treatment T8 NAA 150ppm was recorded significantly minimum at days to first harvest (57.267) and maximum in fruit weight (134.933), fruit length (14.107), fruit diameter (4.453), No. of fruits per plant (11.867), average yield per plant (1,609.100), yield tonne per hectare (10.725).
