This research was conducted to determine the yield and yield components of seven hybrid corn varieties (Luce. Doge, P-3394, Zeneca. Ant-90, T-1595, LG-60) ki Konya ecological conditions and was arranged randomized complete biock experimental desing with three replications. Hybrid com varieties were sown 17 May 2000 and were harvested 27 October 2000. The plants were applied 20 kg N $da^{-1}$(at sowing, stem elongation and before tasseling (h kg N $da^{-1}$. 9 kg N $da^{-1}$. 5 kg N da'1 respectively). 6 kg $P_2O_5 da^{-1}$ (at sowing) and 6 kg K2O $da^{-1}$ (at sowing).The plants were watered six times. Tho grain yield of varieties ranged from 866 kg $da^{-1}$ (Zeneca) to 1283 kg $da^{-1}$ (P-3394) and mean yield was 1094.7 kg $da^{-1}$. Grain moistures in the harvest ranged from 25.85 %(Ant -90) to 32.11%(Doge),flowering times ranged from 72.7 days (Am-90) to 87.0 days (Doge).The correlation between grain yield and grain weight per ear and grain number per row was significant statistically.
