Abstract :This study was conducted at Bahri Dagdas International Agricultural Research Institute’s research fields in between 2005 and 2006 years in Konya Province. In the research, it was used that split split plots in randomized complete blocks experimental design with three replications. Irrigation systems insert ignore into journalissuearticles values(drip and furrow irrigation);, varieties DK-585 insert ignore into journalissuearticles values(FAO 500);, OSSK-602 insert ignore into journalissuearticles values(FAO 600); and P-31G98 insert ignore into journalissuearticles values(FAO 570);, plant densities insert ignore into journalissuearticles values(59520 plants ha־¹, 71420 plants ha־¹, 79360 plants ha־¹, 89280 plants ha־¹); were randomized placed to main plots, sub plots and sub sub plots, respectively. Accord-ing to results of the research Later cv. P-31G98 insert ignore into journalissuearticles values(FAO 700); had the highest grain yield, plant height, first ear height, rate of ear to cob, moisture content in physiological maturity. Mid cv. OSSK-602 insert ignore into journalissuearticles values(FAO 600); had the highest ear diame-ter, kernel number per ear, 1000 kernel weight and protein ratio. In first year ear length and hectoliter had not effected from hybrid corn varieties but in second year OSSK-602 had highest ear length and DK-585 had highest weight of hectoliter.
