ABSTRACT

The experiment was conducted to determine the weed vegetation due to the effect of planting methods and weeding regime. Two factors included in the experiment were: methods of planting and weeding regime. The results revealed that weed vegetation in the two methods of planting varied remarkable. Fifty-five weed species belonging to 17 families infested the crop. Among the weed species, Fimbristylis miliacea (L.) Vahl was the principal weed in direct seeded aus rice and Panicum repens L. in the transplanted aus rice. Twenty-four weed species were found to grow only in the direct seeded crop and only eight in the transplanted crop. Weed density and weed dry weight was significantly affected by the method of planting and weeding regime. Weed density and dry weight was significantly higher in direct seeded than in transplanted crop.
