Abstract: The integration mineral fertilization, organic fertilization and foliar application of micronutrients become necessary to save mineral fertilizers and increase the productivity of maize yield and its quality. As for, a field experiment was carried out during the two successive summer growing seasons 2016 and 2017 at reclaimed sandy soils in the western district of EL- Minia city, El- Minia Governorate, Egypt, to study the efficiency of foliar fertilization by Iron, Zinc and Manganese and organic manure under N-fertilizer levels on maize crop (Zea maize L), 10 hybrid cultivar. The experiment was carried out as a split - split plot design with three replicates; the main plots were micronutrient foliar application (untreated and with spray); the split plots were three levels of organic manure (0, 5, 7.5 ton fed.-1) and the sub split plots were three rates of nitrogen fertilizer (75, 105, 140 kg N fed.-1). Results indicated that foliar application of micronutrients, addition organic manure and N fertilizer levels had a significant effects on all studied parameters (plant height, ear weight kg fed-1, kernels yield kg fed-1 and chlorophyll, concentrations N, P, K, Fe, Mn and Zn) in kernels and leaves and kernels quality (100- kernel weight, carbohydrate %, oil % and protein %) Where, ear weight kg fed-1 and kernels yield kg fed-1 insignificant affected micronutrients. The interaction between micronutrient foliar application, organic manure and nitrogen fertilizer levels had significant effect on all studied parameters excepted content of K in leaves and Mn in kernels was insignificant. Also the interaction between micronutrient foliar application and organic manure had significant effect on all studied parameters except ear weight kg fed.-1, kernels yield kg fed.-1 and Mn in kernels was insignificant. As well as the interactions between micronutrient foliar application and nitrogen levels was significant affected on all studied parameters excepted ear weight kg fed.-1, kernels yield kg fed.-1 and Mn in kernels was insignificant. Also, the interaction between organic manure and nitrogen levels had significant effect on all studied parameter. So, this study can be conclude with fertilization maize crop in sandy soils with micronutrient foliar application ( Fe + Zn + Mn) at three times at a rate of 200 L/fed in each time, with 7.5 ton fed.-1 organic manure and mineral N-fertilization at rate of 105 kg N fed.-1 (313.2 Kg ammonium nitrate fed.-1) with addition the constant recommended doses of phosphorus and potassium to achieve the highest maize grain yield under the same conditions
