Abstract

The aim of this investigation was to study the effect of different levels of pre-harvest chemical sprays on some Agronomic traits in Bitter gourd (Momordica charantia l.) cultivarscv., CO1, MAHY101, US6214, Palee and Roma. There were nine treatments with four chemicals, viz., GA3(250 ppm), GA3(500 ppm), BA(50 ppm), BA(100 ppm), CaCl2 (0.25%), CaCl2 (0.50%), Ca (NO3)2(0.50%), Ca (NO3)2(1.0%), Control (No spray) were sprayed two times starting at the time of flowering and after fruit set, replicated three times in a Factorial Randomized block design. Results revealed that, application of Gibberellic acid (500 ppm) shows significantly early flowering and CaCl2-0.50 percent increased fruitlength, fruitgirth, fruit weight, number of fruits and yield per vine.
