In order to evaluate the effects of different levels in three densities and two rows planting on yield, yield components, morphological characteristics efficiency of corn Hybrid (Ksc 700), an experiment was carried out in Karaj, Iran. This experiment was a factorial evaluation of two treatment, two row spacing, and there plant populations in a with four replications factorial based on randomized complete blocks Three densities: 65000, 75000 and 85000 plant per hectare. The min plots were two rows planting: single and double. And three densities. A project was carried out in spring of the year 2004 and end of them was in 2005 with 24 plot and 6 treatment methods and location of project in 400 hectare researching farm of Karaj Seeds and plant institute. The results showed that on most characters: Successful production yield with 15.52 ton per hectare and plant height, the height of first ear, stem diameter, ear diameter, ear wood diameter, number of grain in row, number of row in ear, biomass weight, ear length, leaf area, ear number .Single row planting and 65000 density treatment had more level on the measured characters was significant.
