Abstract:
A field experiment of a trellised bitter gourd using gibberellic acid (GA3) an exogenous plant growth regulator (PGR) was conducted from December 2016 to May 2017 at City of Batac, Ilocos Norte, Philippines. Bitter gourd is a good source of vitamins and minerals which are good to health. The study was conducted to attain the following objectives: 1) to determine the effect of GA3 on flowering and fruit yield of bitter gourd; 2) to determine the best concentration that give high yield of the tested crop; and 3) to determine the profitability of growing bitter gourd using GA3. Four concentrations (0, 10 ppm, 25 ppm, and 50 ppm) of GA3 were used and laid out in Randomized Complete Block Design and replicated thirce. A plot size of 20m2 was used with 1.5 m distance between plots and blocks. One plant per hill was transplanted in 1 m between rows and 0.75 m between hills. Spraying was done at 20, 40, and 60 days after transplanting. GA3 application had positive effect on the number of staminate flowers, number of fruits per hill, and fruit yield. GA3 at 10 ppm resulted to more number of staminate flowers but further increased of concentration to 25 ppm produced comparable flowers. More number of fruits/hill and fruit yield per hectarewere attained using 50 ppm than no application. Application of the PGR significantly increased the fruit yield.GA3 application was profitable than no application
