Abstract: 
An experiment was conducted as a split - split plot in form of a randomized block design with four replications in Cilakhor region of Iran in 2004. The main factor was the seed planting date with three levels (5, 12 and 25 April), sub factor was the crop density with two levels (160,000 and 250,000 pI/ha) and sub-sub factor was the crop arrangement with two levels (equidistant and non-equidistant). Delaying the planting date caused the increase of biological yield and decrease of harvest index. Increasing the crop density caused the increase of the number of fertile heads per square meter, biological yield, grain yield, and decrease of the number of fertile tillers, the number of grains per head, dry weight of above-ground organs per hill, yield of each hill (P<0.05) and the plant height, the number of grains per head was decreased.
