Two field experiments were conducted at the Agricultural Research and Experiment Center, Faculty of Agriculture at Moshtohor, Kalubia, Egypt, during 1985 and 1986 seasons. The aim of the investigation was to study the effect of some herbicides on soybean growth, yield and its components and chemical contents of seeds. The results indicated that most of weed control treatments improved growth of soybean plants i.e. plant height, number and weight of leaves/plant, number and weight of pods/plant, dry weight of whole plant, seed yield/fad., protein and oil yield/fad. The best treatments favourably affecting most of the characters studied were the three levels of AC with and without surfactant, Amex (2.5 L./fad.)0 Lasso (2.0 L./fadj, Lasso + Linuron (1.5 L. + 0.75 kg/fad.), Scepter (1.05 L./faً.) and hoeing (twice). On the other hand, stomp (1.7 L./fad), Scepter 4 Stomp (0.7 L. + 1.25 L./fad.) and afalon S (1.0 kg/fad.) were inferior compared with other weed control treatments.
