In order to get essential information for efficiency management fields corn.This research was laid out in a split -plot randomized complete block design arranged with four replications, for two years (2001-2002) were the in agricultural research center Iranshahr. Plant density (D1=70000,D2=80000,D3=90000,D4=100000 plant /ha) of main plot and planting patterns (P1=single row, P2=double row with 15cm spaces and P3=double row with 20cm spaces) were the subplots.The result combined analysis over two years showed that plant density, planting pattern and interaction effects were significant at 1% level in grain and forage yield. The study of grain yields D3 plant density with 12800 Kg/ha P3planting pattern with 11500 Kg/ha and D3P2 interaction with 1470 Kg/ha were the highest grain yield. The study of Biomass yield D3 plant density 17500 Kg/ha, P3 planting with 21770 Kg /ha and D4P2 Interaction with 23330 Kg/ha were the highest dry matter .It was concluded that by using double planting pattern the interplant For grain and forage yield respectively competition was increased 90000 and 100000 plant/ha for grain and forage yield respectively.
