Abstract
Field experiments was carried out at the Experimental Farm of the Faculty of Agriculture (Saba Bacha) Alexandria University, during 2006/2007 and 2007/2008 winter seasons. The aim of the present work was to evaluate the influence of N-fertilizer levels (30, 60 and 90 kg N/fed) applied alone or in conjunction with biofertilization (Rhizobacteria, nitrobein and VA-mycorrhizal fungi) on plant growth. Application of bio-fertilizers either alone or in combined with inorganic nitrogen fertilizer lead to significant increases in barley yield characters as compared with their respective control. However, this response differed according to type of bio-fertilizers. The results revealed that biofertilization performed significant improvement in plant productivity. The highest stimulatory effect and the maximum enhancement were exerted in plants treated with VA-mycorrhizal fungi and Nitrobein with 60 kg N/fed.  The highest grain and straw yield, and the highest content of phosphorus and potassium in grain were obtained from the inoculation with VA-mycorrhizal fungi and N fertilizer rate of with 60 kg N/fed. treatment, while the highest N content in grain was obtained from the inoculation with VA-mycorrhizal fungi and 90kg N/fed. treatment. The combination between seed inoculation (N2-fixer) and reduced level of N-fertilizer (60 kg N/fed.) is recommended for reducing the excessive use of mineral N- fertilizers and hence minimizing the adverse environment and human health in agro ecosystems.
