GROWTH AND YIELD POTENTIAL OF LATE PLANTING CABBAGE INFLUENCED BY GIBBERELLIC ACID
The research work was conducted at Sher-e-Bangla Agricultural University farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during July 2016 to June 2017 to find out response of gibberellic acid on growth and yield potential of late planting cabbage. The experiment consisted of four levels of Gibberellic acid such as- G0: 0, G1: 90, G2: 120, G3: 150 ppm GA3 and was laid out in Randomized Complete Block Design with three replications. In case of different doses of gibberellic acid, the highest marketable yield (65.5 t/ha) were found from G2, while the lowest (41.2 t/ha) from G0. On the other hand, the maximum plant height, number of loose leaves per plant and diameter of head (14.8 cm) was recorded from G2 while the minimum from G0. The maximum days to 1st head formation (38.0) was found from G0, while the minimum (34.5) was recorded from G2. So, it can be concluded that 120 ppm Gibberellic acid is suitable for late planting cabbage cultivation.
