GROWTH AND YIELD OF BROCCOLI AS INFLUENCED BY VERMICOMPOST AND GA3

Abstract

A field experiment was accomplished in the Horticulture farm of Sher-eBangla Agricultural

University, Dhaka during the period from October 2018 to March 2019 to study on influence of Vermicompost and GA3 on growth and yield of broccoli. The experiment comprised of three levels of vermicompost viz., V0 (Control)), V1 (5 t/ha), V2 (10 t/ha) and four levels of GA3 viz., M0 (control), M1 (50 ppm), M2 (80 ppm) and M3 (110 ppm) were used in this experiment arranged in Randomized Complete Block Design (RCBD) with three replications. Data on different growth and yield attributes were taken in which all the treatments showed significant variation. The maximum yield (27.29 t/ha) was recorded from V2 (10 t/ha), while the lowest (19.79 t/ha) was recorded from V0. GA3 exhibited a significant influence on total yield per plant. The maximum yield (26.27 t/ha) was recorded from M2 (80 ppm), whereas the lowest (19.80 t/ha) was recorded from M0. Yield per plant was significantly influenced by the treatment combinations of vermicompost and GA3 of broccoli. The maximum yield (32.41 t/ha) was recorded from the treatment combination of V2M2, whereas the lowest (18.19 t/ha) was recorded from V0M0. From growth and yield point of view, it is apparent that the combination of 10t/ha vermicompost with 80 ppm GA 3 is suitable for broccoli cultivation.
