| Abstract | ||
| Field experiment was conducted in Baiji /Salah Aldien during the autumn growing Season in 2013 to study the effect of four Sowing dates ( 107 , 207 , 307 , 108 ) on six hybrids Corn ( Ronaldo, ZP314 , ZP 434 , DKC 5401 , ZP 606 , R 1001 ) on grains yield and Component yield . The experiment was applied by using split plot arrangement in RCBD with three replications . DKC 5401 and R 1001 have given the highest grains yield ( 4,69 and 4,58 ta ha) respectively significant differences between hybrids did not appear in the arrange of 300 grain weight . R 1001 and DKC 5401 have given the highest arrange of grains per row . The first and second date gave highest arrange for grain yield and 300 grain weight and number of ear in plant and there is no difference between Sowing dates on number grains in the row . The interaction of Genetic Compositions and the sowing date have significant effect and the distinction of shahd in the second date in most of studied properties , that is mean that this genetic composition was the most fitness in using its genetic and physiology capabilitics under this agriculture mode . | ||
