In order to evaluate the influence of different tillage methods and autumn pea cultivars (Arman, Hashem, ILC-482) in first cultivation on corn forage yield (variety of Single cross-704) in second cultivation, this research has been done. The experiment was conducted as Split-plot in RCBD with the replication of 4 in Tehran University from Karaj in 2012. The main plots included different tillage systems (Conventional tillage, Reduce tillage, No tillage) that in first cultivation pea cultivars and in second cultivation Single cross-704 corn were planted as sub plot. In second cultivation, the tillage of the main plot was the same as the main plot in first cultivation. The different pea cultivars in first cultivation didn’t have significant effects on corn forage yield. The highest forage yield was related to conventional and minimum tillage. Seedbed preparation costs in minimum tillage is lower than conventional tillage, so this method is suggested to obtain the maximum biomass and grain yield.
