ABSTRACT

An experiment was conducted to find out the effect of growth regulators and stages of spray on seed yield and quality in bitter gourd variety phule green gold during summer-20013. Application of GA3 50 ppm exerted significantly the highest seed yield per plant (10.38g), which was at par with GA3 25 ppm (S1) (10.24), ethrel 250 ppm (S3) (10.04) and ethrel 500 ppm (S4) (10.15). The maximum germination percentage (95.93 %), root length (14.55 cm) shoot length (13.96 cm) vigour index-I (1234)and vigour index-II (5856) were recorded with GA3 50 ppm.
