To investigate the effect of different amounts of Fe and Mn on qualitative and quantitative traits of forage maize (Zea mays L.) hybrid single cross 704, an experiment was conducted as a factorial in a randomized complete block design with 16 treatments and three replications at Qaneat city (Southern Khorasan Province) in 2010. Treatments consisted of 4 levels of FeSO4 (no fertilizer as control and 30, 60 and 90 kg/ha) and 4 levels of MnSO4 (no fertilizer as control and 10, 20 and 40 kg/ha).With increase of Fe and Mn fertilizers, a significant increase was occurred in plant height, leaf number, stem diameter, dry weight (stem, leaf, maize) and dry forage yield. Increased rates to optimum level (Fe-60 and Mn-20 kg/ha fertilizers according to the soil test), increased the yield, but more fertilizer reduced the quality. Therefore for forage with good quality and quantity, 60 and 20 kg/ha of Fe and Mn fertilizers, respectively is recommended for this area.
