| Abstract | ||
| This experiment was conducted during the fall season of 2011 and spring season of 2012 in a field in Sadat AL-Hendia , 25 Km at the East North of Babylon to study the effect ofplantingdates ( 10July , 25July and 10August.) as well as (1March ,10 March, 20March ) in grwoth and yield of five synthetic variates( 5018 , 5012 , Rabea , Bohooth 106 and Maha)of corn.In the fall season of 2011 and spring season 0f 2012 respectivaly in a split plot in RCBD with three replications ,the main plots were the genotypes while planting times represent the sub-plot .Result can be summarized as follow . There is an obvious significant difference among CVS regarding growth, yield and quality The synthetic varietiesbohooth 106 took longer time from emergence to full bloom and from emergence to physiological maturity for both seasons . Same Cv gave the highest means of plant hight , raw number /ear , seed number / ear , grain yield ( 9.49 and 8.34 ton / ha )and Oil content (8.15 and 8.70%) and for both seasons , Planting dates had a significant impact on most characters studied . planting on July 25th took least period from emergence to full bloom grain yield (9.89 tonha) .The date10August gave the highest means of plant high , leave area and oil percent. on the other hand 20 st march gave least days number from emergence to female blooming and from the later date to the physiologicalst maturity march1st gave the highest grain yield (8.07)tonhaand and oil content (7.09%) . | ||
