GROWTH, YIELD AND QUALITY OF BROCCOLI INFLUENCED BY PINCHING AND GIBBERELLIC ACID (GA3)

Abstract

The experiment was conducted in the Horticulture Farm and laboratory of Sher-e-Bangla Agricultural University, Dhaka during October 2016 to February 2017. The experiment consisted of two factors: Factor A: Pinching method 0 : No pinching : Pinching apical meristem at 15 days after transplanting 2 1 ii 3

: Pinching apical meristem at 30 DAT and P : Pinching axillary buds at 45 DAT; and Factor B: Gibberellic acid-GA

0 : 0 ppm 1 : 50 ppm and G 2 :100 ppm GA . The two factor experiment was laid out in Randomized Complete Block Design with three replications. Pinching methods and gibberellic acid influenced significantly on most of the parameters. In case of pinching, the highest curd yield 1 and the lowest curd yield 3 . For gibberellic acid, G 1 0 performed the highest curd yield . For combined effect, the highest curd yield 0 1 G 1 and the lowest curd yield . The highest benefit cost ratio 1 G 0 and the lowest benefit cost ratio (1.09 0 G . So, pinching apical meristem at 15 DAT with 50 ppm GA 3 0 can be used for commercial broccoli production.
