Abstract
A field experiment was conducted to evaluate the efficiency of herbicide mixture of almix (metasulfuron methyl + chlorimuron ethyl) and butachlor to control both grassy and broad leaved weeds. Application of almix 0.004 kg/ha mixed with butachlor 0.938 kg/ha at three days after transplanting (DAT) was at par with hand-weeding twice at 20 and 40 DAT in controlling weeds and higher grain yield. This application increased the grain yield by 45.1% over the unweeded check. There was a negative linear relationship between weed dry weight and grain yield.
