Abstract: IGH Fe content in the New Valley soils hinders the absorption of both P and Zn by plants, which is negatively reflected on crop production.Field experiments were carried out in two successive seasons at two sites under the conditions of the New Valley soils in order to increase wheat yield by the integration between mineral (P and Zn) and bio-fertilization (Mycorrhiza and Azotobacter).The first experiment was carried out at El-Monera (sandy soil), El-Kharaga Oasis, while the second one was carried out at Al-Kaser (clayey soil), El-Dakhlla Oasis.Grains of wheat variety Sakha 93 was cultivated in both locations.Application of mineral P and Zn fertilizers along or with bio-fertilizers increased wheat yield parameters, nutrients content, total antioxidants, and phenols of wheat.Moreover, increasing the application rates of P and Zn decreased Fe and Mn contents in wheat and increased N, K, Zn and Cu contents in the straw and grains.The most effective treatment for yield, nutrients and biochemical contents was by applying P at a rate of 60 kg fed -1 (1 fed = 4200 m 2 ) in clay soils and 80 kg fed -1 in sandy soils with spraying Zn at a rate of 250 mg L -1 with the Mycorrhizae and Azotobacter applications.This treatment could achieve 5.45 and 2.21 Mg fed -1 for straw and grains respectively in the sandy soil while, 9.5 and 4.16 Mg fed -1 in the clay soil.This study revealed that combining bio-and mineral P and Zn fertilizers application could decrease the negative effect of high Fe content in soils and increased wheat production.
