CHEMICAL WEED CONTROL IN TRANSPLANTED RICE (ORYZA SATIVA) IN HIRAKUD COMMAND AREA

Abstract

A field experiment was conducted during the rainy seasons of 2002 and 2003 on transplanted rice at Chiplima, Orissa to evaluate the efficiency of herbicide mixture of almix and butachlor to control both grasy and broad leaved weeds. Application of almix 0.004 kg mixed with butachlor 0.938 kg/ha at 3 days after transplanting (DAT) was as good as hand-weeding twice at 20 and 40 DAT in controlling weeds and achieving grain yield. Application of almix 0.004 kg + butachlor 0.938 kg/ha increased the grain yield by 45.1% over the unweeded check. There was a negative linear relationship between weed dry weight and grain yield.
