SCHEDULING IRRIGATION FOR SUGARCANE WITH CABBAGE AS INTERCROP

Abstract

An experiment was conducted in Bangladesh Sugarcane Research Institute (BSRI) farm at Ishurdi during 1997-98 cropping seasons to develop an irrigation schedule for sugarcane with cabbage as intercrop using pan ratio (PR) method. Irrigation was applied during pre-monsoon only. No irrigation was applied during monsoon or post-monsoon. The highest yield of sugarcane as well as cabbage were obtained when irrigation was applied at PR= 1.0. With this PR, the highest yield of sugarcane (109.79 t ha-1 ) was obtained with 430 mm irrigation water in addition to 176.43 mm of effective rainfall. The highest yield of cabbage (21.66 t ha-1 ) was obtained with 310 mm of irrigation water.
