Abstract

To investigate the effects of PLANT DENSITY on GRAIN YIELD and its components of corn hybrids, a split plot experiment on randomized complete block design with three replications was carried out in the city of Eyvan, in 2008. Varieties of Ksc 704, Ksc 604 and Ksc 647 arranged as factor A and PLANT DENSITY at 5 levels, including 5.5, 7, 8.5, 10 and 11.5 plants per square meter were factor B. Analysis of variance showed that the effect of density on plant height and ear length from ground, was significant and the impact of these two factors on other characteristics was significant. The maximum number of rows at per ear (15.06), in hybrid of Ksc 604 was produced and density 5.5 plants per square meter with 15.13 were of the highest value. The Maximum highest total number of grains per ear (375.8) in cultivar Ksc 704 was produced and Minimum, in variety of Ksc 604 was obtained. 1000 seed weight in cultivar Ksc 604 and Ksc 704 with 278.5 and 269.4 g, had the highest and lowest rates and 1000 KERNAL WEIGHT from density from 5.5 to 11.5 plants per square meter showed a decreasing trend. According to the results, the variety of Ksc 704 In terms of production the highest GRAIN YIELD (9196 kg ha), and density of 10 plants per square meter, was seen as the best variety and density.
