PERFORMANCE OF WHEAT-BUSHBEAN INTERCROPPJNG UNDER DIFFERENT ROW RATIOS

Abstract

An experiment on the performance of wheat - bushhean intercropping at different row ratios (3:1, 4:1, 5:1, 6:1, 3:2, 4:2, 5:2, 6:2, 7:2 and 8:2) along with the sole wheat and hushbean was conducted at the Agronomy Field, Sher-e Bangla Agricultural University, Dhakai 207 during the period from December, 2005 to March. 2006. The experiment was laid out in a randomized complete block design with three replications. At the maturity, seeds were harvested, while at the vegetative stage, fresh pods of bushbean were considered as yield. Among the intercroppin g, patterns, the highest wheat equivalent yield values of 5.095 and 4.734 were obtained with 3:2 row ratios of wheat and bushhean intercropping pattern at maturity and vegetative stages respectively. It was observed that the highest land equivalent ratio value was obtained with 4:1 row ratio at maturity stage while with 3:2 row ratio at vegetative stage. The highest monetary advantage (Tk.t7355.40/lia) was found with 3:2 row ratio when pods of bushhean were harvested at marketable size. But when crops were grown for seed production, the highest monetary advantage (1k. 4466.67 /hia) was found with 4:1 row ratio.
