Abstract
In order to investigate the effect of tillage systems and plant density in two plant pattern, on kernel yield and its component on corn (Zea mays L.cv.sc704), an experimental design , randomized complete block in a strip factorial was used, treatments arrangement with four replications in north of Iran in 2010. Main plot was subjected to tillage systems in three levels: 1. Rotary system (RS). 2. Disk system (DS) - 3. Plow and Disck system (PDS). Other factors were plant density in three levels (60000, 70000 and 80000 plant/ha) and plant pattern were conventional row (linear) and new two rows (zigzag).The results indicated that the grain yield and silage yield, which were affected by tillage systems did not show any significant difference,while the grain yield and silage yield, which were affected by plant density showed significant difference. With the increase of density from 60000 to 80000 plants/ha, grain yield and silage yield increased, an amount of from 9.793 to 10.92 and 62.68 to70.85 t/ha respectively. Grain yield and silage yield were not affected by plant pattern.
