Abstract
The herbicides experiment was conducted for two consecutive summer seasons (2014, 2015) at Altraa village, Sharg Elneel Unit, Dongola Locality, Northern State, Sudan located within latitude 16° and 22°N and longitude 20° and 32°E to determine fresh pod yield loss due weed competition and to evaluate and compare the effects of Fusilade applied as post-emergence at 0.7, 1.1, 1.3 and 1.5 l/fed and glyphosate applied pre-emergence at 0.3, 0.4, 0.5 and 0.6 l/fed and applied post-emergence at the same rates. Results obtained from this experiment indicated that, unrestricted weed growth significantly reduced fresh pod yield (kg/fed) by 67.40% in both summer seasons. Results obtained from this experiment reported that, Fusilade herbicide was the best in controlling graminae weeds while glyphosate herbicide was the best in controlling broad-leaved weeds in both summer seasons. Also results obtained from this experiment reported that, among the two herbicides treatments the best weed control was achieved by glyphosate which applied post-emergence at 0.6 l/fed while Fusilade at 1.5 l/fed treatment applied postemergence gave higher fresh pod yield in both summer seasons. The use of the two herbicides treatments reduced significantly weed biomass (g/m2).
