EFFECT OF NITROGEN RATE ON YIELD AND YIELD COMPONENTS OF WHEAT IN WILD OAT INFESTED CONDITION

摘要: Research was performed to evaluate nitrogen effect on wild oat-wheat competition. A field study conducted in 2011 at Ahwaz, Khuzestan, Iran. Two levels of oat (presence and absence) as main factor three rates sub were studied using a split plot design with four replicates. Maximum plant height increased supply weed free presence condition. Wheat maximum condition more than those grown Wild wheat all rate. The 128.82 cm 150 kgNha -1 Addition biomass production. rate the relative showed application reduced while increased. These results indicate that competitive effects may increase N supply.
