In order to achieve the most appropriate quantity and plant density of corn which could best use sunbeam and soil nutriets equally and could have the highest yield seed, an experiment in factorial way according to the base design of complete randomized blocks in three replications was performed in the summer of agricultural year of 2006 in the region of kuhdasht. Density factor was in four levels including: plant densities(6,7,8,9 plant/m2) and cultivar factor was in three levels including :(V1=704),(V2=677),(V3=630).The gained results also showed that by increasing plant density the yield of seed increased and the highest seed yield from the density of 9 plantsin a cubic metre was gained amount to13/23 tons per hectar which had a significant superiority in proportion to the other plant density and it shows that the conditions of sun beams is suitable in kuhdasht and we can increase plant density. The effect of numbers on the yield of seed became meaningful and the maximum seed yield was gained from the number of cultivar677 about12/15 tons per hectar which in proportion to thenumbers of cultivar 630 and 704 had yield superiority respectively1/45 and 1/93 tons per hectar. The comparison of the averages of crop intensity and cultivar interaction showed that the highest yields of seed was gained respectively amount to 14/55 and 16/06 ton per hectar from the numbers of cultivar 630 with density of 9 plants in a cubic metre.
