EFFICACY OF VERMICOMPOST AND BIOCHAR ON THE GROWTH AND YIELD OF GREEN CABBAGE

Abstract

The experiment was carried out at the Horticulture Farm of Sher-e-Bangla Agricultural University, Dhaka during the period from October 2017 to March 2018. The experiment consisted of two factors. Factor A: Four biochar treatment viz. B 0 (0 t ha -1 ; Control), B 1 (2 t ha -1 ), B 2 (6 t ha -1 ) and B 3 (10 t ha -1 ) and three vermicompost treatment viz. Vc 0 (0 t ha -1 ), Vc 1 (4 t ha -1 ) and Vc 2 (8 t ha -1 ). The experiment was laid out in the two factors Randomized Complete Block Design with three replications. Regarding combined effect of biochar and vermicompost application, all the studied parameters including growth, yield and yield contributing parameters were significantly influenced. In case of different levels of biochar the highest yield of cabbage (48.08 t ha -1 ) was found from the treatment B 2 and the lowest yield of cabbage (27.86 t ha -1 ) was obtained from the control treatment B 0 . For different levels of vermicompost the highest yield of cabbage (46.45 t ha -1 ) was observed from the treatment Vc 2 and yield of cabbage (33.98 t ha -1 ) was also achieved from the control treatment Vc 0 . For combined effect the highest yield of cabbage (52.75 t ha ) was obtained from B 2 Vc 2 and the lowest result was found from the treatment combination of B 0 . In terms of economic analysis, the highest gross return (Tk.6,33,000) was obtained from B 2 Vc 0 but the highest net return (Tk. 3,80,048) was obtained from the treatment combination of B 1 Vc 2 Vc 1 with highest BCR (2.96) and the lowest BCR (1.25) was obtained from B 3 has

Vc 2 treatment combination. So, it can be summarized that B 1 given the maximum output in terms of benefit cost ratio (BCR) and yield.
