Abstarct: Biologic fertilizers are used as a fundamental solution for the development of integrated management systems of plant organic and mineral nutrient and increasing of quality and quantity of food per unit area. In order to achieve the goals of sustainable agriculture and producing healthy foods, a factorial experiment in a completely randomized plot design with the tixtle of: The effect of Mycorrhiza Fungi at different levels of P and K fertilizers on growth and yield of corn (Zea mays L) was conducted with 4 replications in Shahrood University Reaserch Farm. Treatments were Mycorrhiza Glomus mosseae, Phosphorous in 3 levels 0, 50 and 100 kilogram in hectare and Potassium in 2 levels 0 and 100 kilogram in hectare. The results suggested significant effect of mycorrhizal fungi on yield, 100 seed weight, harvest index and seed P percentage. Yield, 100 seed weight, harvest index, plant height and ear length of maize influenced by the interactions between mycorrhizal fungi and K fertilizers. Interaction of mycorrhiza and phosphorus fertilization was significant on yield, harvest index and seed phosphorous content. The interaction between potassium and phosphorus fertilizers was significant on biological yield, seed yield, the number of kernel per row, kernel rows per ear, harvest index and seed phosphorous and potassium percentage. Mycorrhizal fungi with 100 kilogram in hectare K and 50 kilogram in hectare P increased seed yield up to 31.57 percent.
