Abstract:
The experiment was conducted to investigate the growth and yield of brinjal with GA
3
at Horticultural farm, Sher-e-Bangla Agricultural University, Dhaka during period fromOctobor 2012 to February 2013. Two factors experiment included 3 brinjal varietiesviz. V
1
(BARI Begun-4), V
2
(BARI Begun-7), V
3
(BARI Begun-8) and 4 Gibberellic
Acid (GA
3
) concentrations viz. G
0
(Control), G
1
(50 ppm GA
3
), G
2
(100 ppm GA
3
) and
G
3
(150 ppm GA
3
) was outlined in Randomized Complete Block Design (RCBD) with
three replications. Experimental results showed that variety had significant effect on allparameters except days to 1
st
flowering and days to 1
st
fruit set. The highest yield (50.4t/ha) was recorded in V
1
while the minimum yield (38.0 t/ha) was recorded in V
3
.Concentration of GA
3
also significantly influenced all the growth and yield attributes
except number of leaves, number of branches, days to 1st flowering and days to 1
fruitset.The results showed that G
2
produced maximum yield (51.6 t/ha) while the minimumyield (32.4 t/ha) was recorded in G
0
plants. For combined effect, the highest yield (59.2t/ha) was recorded in V
1
G
2
and the lowest (28.6 t/ha) in V
3
G
0
. So, it can be concludedthat ‘BARI Begun-4’ treated with 100 ppm GA
3
combindly gave the maximum yield.
