Abstract :
To study the effects of micronutrient concentrations of iron and zinc on maize (Zea maysL.) KSC 260 factorial experiment in a randomized complete block design with four replications Education - Faculty of Agriculture, Islamic Azad University of Varamin -Pyshva was conducted in July 1392. First of iron sulphate fertilizer at three levels (zero, two, four thousand liters) and the second zinc sulfate fertilizer at three levels (zero, four, eight per liter) is sprayed in two steps (first eight-leaf stage and secondly tassel emergence) was performed. The results showed that the interaction between the treatment of iron concentration on four thousand and four hundred on a test characteristics and biological function of the average 24856.3 (Kg.ha), with an average yield of 9496.5 (Kg.ha), with an average of 9.06 percent protein performance fibers with an average 860.4 (Kg.ha), with an average of 38.72% and harvest index (LAI), with a mean value of 6.27 compared to the control (non-use spray), giving the greatest impact on corn (Zea mays L. ) KSC 260 is in Varamin.
