In order to investigation grain yield and yield components of early mature corn hybrids in rotation with wheat and rapeseed in conventional tillage and No-tillage systems this experiment carried out for two years. The combined analysis of variance showed previous crop has significantly effect on corn grain yield. Corn grain yield after wheat crop was 6089 kg/ha and after rapeseed was 5629 kg/ha. Yield components such as numbers of row per ear and seed number per row were not affected significantly. Cultivation systems had not significant effect on grain yield and yield components. Plant establishment percentage also was not affected by cultivation systems—this trait only measured in second year of experiment. Grain yield was completely different between first and second year of experiment. Planting date of first year experiment delayed for 13 days so yield decreased from 7163 to 4556 kg/ha. There were significantly different among corn hybrids grain yield and Ksc201 had the highest grain yield.
