Abstract:
The effect of different levels of GA
3
and nitrogen were tested on the cabbage cultivar
Atlas 70' in the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka
during November 2015 to March 2016. The experimental plot was laid out in
Randomized Complete Block Design (RCBD) with three replications. The twofactorial
experiment
was consisted of three levels of GA
3
; G
0
= 0 ppm, G
= 60 ppm
and G
2
= 80 ppm and four levels of nitrogen; N
0
= 0 kg/ha, N
1
1
= 210 kg/ha, N
= 240
kg/ha, N
= 270 kg/ha. In case of gibberellic acid, the highest yield (87.87 t/ha) was
obtained from G
1
3
and lowest yield (74.29 t/ha) was obtained from G
2
. For nitrogen,
the highest yield (85.41 t/ha) was obtained from N
2
and lowest yield (70.83 t/ha) was
obtained from N
0
. Among all treatments combinations G
1
N
2
produced the highest
yield (97.77 t/ha) and G
0
N
0
produced lowest yield (68.88 t/ha). So, 60 ppm GA
3
and
240 kg N/ha may be used for cabbage cultivation.
