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.
