EFFECT OF DIFFERENT LEVELS OF GIBBERELIC ACID AND BORON ON GROWTH AND YIELD OF BROCCOLI

Abstract

The study was conducted at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka to find out the effect of different levels of gibberellic acid and boron on growth and yield of broccoli. The experiment consisted of two factors: Factor A: Gibberellic acid 3

: control, G 1 : 100 ppm, G 2 : 200 ppm GA and Factor B: boron 0 : control, B 1 : 100 ppm, B 2 3 : 200 ppm B. The two factors experiment was laid out in Randomized Completely Block Design with three replications. In case of different levels of GA , the highest main and secondary curd yield

3 , while the lowest yield 0 2 . For different levels of boron, the highest main and secondary curd yield , whereas the lowest yield . Due to interaction effect, the highest main and secondary curd yield 2 B 2, 0 whereas the lowest yield The highest benefit cost ratio and the lowest 0 B From growth, yield and economic point of view, it is apparent that the combination of 200 ppm GA 0. with 200 ppm boron was suitable for broccoli cultivation.
