The current work was conducted to illustrate the effectiveness of organic manure use to substitute part or all the chemical fertilizers as well as the bio-fertilizers and foliar spray of micronutrients effect on maize yield crop production and grain mineral content. A field experiment was carried out in 2004/2005 where, maize plants were grown on sandy and clay soils. Fertilization treatments which were used in these experiments were foliar application with micronutrients, organic manure application, inoculation of maize seeds with rhizobactrin a composite contains Rhizobium leguminosarium bacteria, foliar spraying with micronutrients, combinations of them and control. Results showed significant increase in straw and grain yields of maize plants using the substantial addition of the tested fertilizers when applied individually or together. The highest straw and grain yields were recorded with the treatments of bio-fertilizers alone or in co mbination with other fertilizers. Nitrogen and phosphorus uptake in grains were significantly increased with using all fertilizer treatments while, no significant increase in K content due to such fertilizers treatments was noted except with treatments of organic manure plus bio-fertilizers and micronutrients plus organic manure N, P and K contents were increased with adding each one of the tested treatments. Fe, Mn and Zn uptake in both grains and straw increased by fertilizers application.
