OKRA PRODUCTION IN THE FISH POND THROUGH THE APPLICATION OF GIBBERELLIC ACID AND VERMICOMPOST

Abstract

The experiment was conducted in the fish pond through determine the effect of gibberellic acid and vermicompost on okra production during July to October 2019 at the fish pond near Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka. The experiment was consisted of two factors; Factor A: GA3viz. (i) Go; 0 ppm GA3 (control) and (ii) GI; 100 ppm GA3 and Factor B: Vermicompost viz. (i) Yo; 0% vermicompost + 90% coco peat + 10% broken bricks + dissolved nutrients of fish pond water (control), (ii) VI; 20% vermicompost +70% coco peat + 10% broken bricks + dissolved nutrients of fish pond water and (iii) V2; 40%vermicompost + 50% coco peat + 10% broken bricks + dissolved nutrients of fish pond water. The experiment was laid out in Completely Randomized Design (CRD). In terms of GA3 application, the highest fruit yield (405.66"g plant") was found from GI whereas the lowest fruit yield (336.03 g plant") was found from Go. Regarding vermicompost, V2 showed higher growth and yield attributes which resulted the highest fruit yield (421.00 g plant") whereas the lowest fruit yield (303.80 g plant") was found from Yo. Considering interaction effect, GJV2 showed highest fruit yield (470.10 g plant") whereas the lowest fruit yield (290.60 g plant") was found from GoVo. So, the treatment combination of GIV2 can be treated as the best among all the treatment combinations.
