Abstract:
Afield experiment was conducted for one season 2009/2010 at
demonstration farm of department of agronomy, college of agricultural
studies, Sudan University of science and technology to study the effect of
seed rate on growth and yield of three cultivars of soybean. Treatment was
the two factor combinations of seed rate three levels SR1= 48.000,
SR2=195.000 and SR3= 146.000 and three cultivars (Egyptian, 1448 and
1905) arranged in split-plot design with four replications. The results
showed that the seed rate no significant differences on vegetative stage
In soybean enough the significant effect on vegetative
stage between cultivars and cultivar 1905 recorded as
highest characters vegetative. The seed rate had significant
effect on grain yield in the presence of treatment V 2SR3
recorded as higher yield comported with other treatments
Forage seed rate was not significant on dry weight forage.
the difference between the three cultivars was significant in
most parameters measured by cultivars 1448.
