Abstract

A comparative study to evaluate the effect of chemical, commercial bio-fertilizers, arbuscular mycorrhizal fungi (AMF) and their combinations on the soil properties and some physiological metabolites of maize (Zea mays L.) was carried out on a pot experiment under field conditions. Six species of the AMF were used for inoculation were isolated and identified from rhizospheric soil of cultivated maize. Application of half the recommended dose of chemical fertilizers (CFhd) mixed with commercial bio-fertilizers (BF) to mycorrhizal plants led to the highest root colonization by hyphae (97.67%), vesicles (76.744%) and arbuscules (58.140 %). This reflected on the plant metabolism and significantly increased the root soluble protein (SP) and soluble sugars (SS). The highest content of total free amino acids in roots (TAA) and soluble sugars in shoots obtained under application of the full recommended dose of chemical fertilizers (CFfd) to the mycorrhizal soil. Mycorrhizal soils amended with

Conclusion

This study indicated that while CF increase both of the potential and available supply, the AMF and BF increase the available supply of the plant-nutrients content of the soil. The maize growth and metabolism are determined by the status of the chemical changes taking place in the soil and plant, and not completely by the potential plant-nutrient content of the soil.
