Effect of Sowing Date on Yield and Yield components of maize (Zea mays L)

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.
