This study assessed the effects of different methods of tillage and crop densities on corn yield ( KSC301) in Dasht Naz in 2002 and 2003 . Strip block design containing 2 factors of tillages method ( No tillage , disk and plow + disk ) and crop density ( 70000 , 80000 and 90000 P.ha –1 ) , With 3 replications in randomized complete block design was employed . Inter row space was 75 centimeters and each treatment was planted in four rows .Data were taken from two middle rows , these harvested rows had 13.5 m2 area. Biennial result mean comparison with duncan test showed that in land preparing systems,disk treatment was the best . Disk treatment with 90000 p . ha –1 had the highest yield (9.314 T.ha –1 ).
