Performance elements, an experience is implemented in summer 2010, at the station of Ahvaz agricultures research center as broken plot in a design framework of accidental blocks with 3 repetition. The main factor of different amount of nitrogen include 3 level N60, N120, N180 kg/lit pure nitrogen of urea resource & secondary factor of weeds intervention include 3 levels (i) continuous weed until the end of corn growth period (w1), (ii) one time weed in 6 leave level (w2), (iii) complete intervention of weed with corn until the end of corn growth period. The acquired results indicated that weed intervention on yield & yield component has a meaningful effect & by increasing the period of weed intervention, the grain yield is reduced. Increasing weed competition make a meaningful effect on grain weight, performance, biological performance & harvesting index. But increasing amount of nitrogen from N120 kg/lit to N180 kg/lit had not a meaningful effect on grain performance & in some cases due to high pressure, the competition from weed make reduction of grain performance, (once weed treatment & all season intervention). In low & high level of nitrogen, biological performance & corn performance is respectively affected by weed. According to the results of this experience, it can be resulted that by reducing competition time of weed, increasing N can make grain performance enhancement. In contrast to weed competition time, increasing nutritive ingredient is an affected weed growth more than agriculture plant &makes weedcompetitionpowerenhancement.
