Corn is a strategic crop in Kermanshah province. An experiment was conducted to the study of optimum application of N, P, K, Mg and Zn fertilizers on major area of corn production in Kermanshah(Mahidasht and Ravansar). This experiment was carried out with four fertilizers treatments in a Randomized Complete Block Design with five replication in each site and with fertilizers treatments were included: T1: N+P(N Pre-Side dress Nitrogen Test and P based on soil test). T2: T1+K(kg.ha-1 KCl, based on soil test). T3: T2+Mg(kg.ha-1 MgSo4, based on soil test). T4: T3+Zn(kg.ha-1 ZnSo4, based on soil test). The corn variety K.S.C. (MO 17XB73) was sown at a number of 7000 plant ha-1. The results showed that application of N, P, K, Mg and Zn treatments caused increased grain yield(equal 1020 kg.ha-1) and T. K. W. was significant differences compared to control treatment in protein and P, K, Fe, Zn and Cu, uptake of grain.
