Role of plant growth regulators on seed quality and seed yield of bitter gourd (Momordica charantia L.)
Year: 2025
Type: article
Abstract: The bitter gourd is the most popular vegetable crop in India as it gives higher yield and maximum returns to the farmers. A field trial was carried out to study the quality seed yield at different growth stages in bitter gourd during Kharif season of 2020. Three concentrations each of NAA @ 50, 75 and 100 ppm, GA3 @ 25, 50 and 75 ppm and ethephon @ 150, 200 and 250 ppm along with control (P0) were applied at three different stages viz., S1 (two leaf stage), S2 (two leaf + four leaf stages) and S3 (two leaf + four leaf stages + bud initiation stage). Amongst different plant growth regulators, foliar application of ethephon @ 250 ppm at stage S3 recorded the maximum seed weight/fruit and seed yield. Highest seedling length, seedling dry weight, vigour index 1 and vigour index 2 were obtained when the plants were sprayed with ethephon @ 250 ppm at stage S3 followed by stage S2. Significantly the maximum germination, seed viability were recorded with ethephon @ 250 ppm applied at stage S3 and minimum was recorded under control, i.e. water spray at stage S1. Hence, it may be concluded that foliar application of ethephon @ 250 ppm sprayed three times at two leaf, four leaf and bud initiation stage would be beneficial for higher seed yield and better quality of seeds.
