Abstract:
The experiment was conducted in the Horticulture Farm of Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh to evaluate the role of pruning methods on growth,
yield and profitability of brinjal under three varieties. The experiment consisted of two
factors. Factor A: Methods of pruning as P

= Control, P

= Old leaf remove, P
= Lateral
branch pruning, P
= Old leaf remove and lateral branch pruning and Factor B: 3
varieties of brinjal as V

10. The experiment was laid out in a Randomized Complete Block Design with
three replications. In case of pruning, the highest number of flower (38.87), the
maximum number of fruit per plant(27.83) and the highest yield (49.73 t/ha) were
recorded from P
3
treatment, while the minimum were from P
treatment. In case of
variety, the maximum number of flower (41.23), the highest number of fruit harvested
per plant (29.23) and the highest yield (52.83 t/ha) were found from V
0
treatment
whereas the lowest from V
treatment. Due to combined effect, the maximum number
of flower (49.20), the maximum number of fruit harvested per plant (33.64), the
highest yield (55.70 t/ha) were recorded from P
2
. So, it can be concluded that ‘BARI
Begun-4’ with old leaf remove and lateral branch pruning gave the maximum yield.
The highest gross return (10,02,600 tk/ha), highest netreturn (6,79,649 tk/ha) and
highest benefit cost ratio (3.1) were obtained from P

yield and economic benefit of brinjal.
