Two field experiments were conducted during 1979 and
1980 seasons at the Research and Experimental Station of
the Faculty of Agriculture at Moshtohor to study the effect
of planting methods (Ilaraty and At ir) and some weed control
treatments on growth characters of soybean and its associated
weeds. The weed control treatments were: Linuron (1.0 kg),
butralin (2.0 L), oxadiazon (2.0’L.), Netribuzin (0.5 kg),
ًiphenamtde (1.5 kg), tridex (1.0 L.), phenisopham (1.0.
L.), mixture cf linuron with other herbicides by using
the half rate in addition to hand hoeing and unweeded treat
ment. Heraty (wet) method depressed significantly the
dry weight of broad-leaved and grass weeds as compared
to the afir (dry) method. On the other hand, hearty method
significantly increased some growth characters of soybean
plants, i.e.,plant height, no. of leaves/plant, dry weight
of leaves as well as whole plant over fair (dry) method.
The herbicidal combinations used in this study were more
effective in controlling weeds and showed good effect on
growth characters of soybean as compared with those of
single herbicides. The interaction effect was significant
on dry weight of weeds and some studied characters of soybean
plants.
