The experiment was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2018 to March 2019. The goal of this study was to determine when to sow cabbage and how much gibberellic acid to use in order to maximize growth and yield. The experiment consisted of two factors: Factor A: Planting time (three different times) as - T1= 05 November; T2= 20 November and T3= 05 December and Factor B: Gibberellic acid (four levels) as- G0= 0 ppm (control); G1= 75 ppm; G2= 95 ppm and G3= 115 ppm GA3, respectively. The two factors experiment was laid out in Randomized Complete Block Design with three replications. Due to the combined effect of Gibberellic acid and planting time, the maximum thickness of head (14.5 cm) and the highest marketable yield (59.4 t/ha) was found from T2G2 whereas the minimum thickness of head (10.8 cm) and the lowest marketable yield (37.1 t/ha) was found from T3G0. The economic analysis revealed that T2G2 gave the maximum benefit cost ratio (2.57). That’s why we can consider that 20thNovember planting time along with 95 ppm GA3 was the best combination for growth and yield of cabbage.
