| Abstract |
A field experiment was conducted in the winter season of 2008/09 at EL-Ismailia Agricultural Research Station, Agric. Res. Center (ARC), to study the effect of inoculation with both cyanobacteria and Azospirillum brasilense, each alone or both in combination, on barley grain and straw yields as well as soil biological activity under different mineral nitrogen fertilizer levels with or without organic fertilization (compost). Results revealed that all treatments increased barley grain and straw yields, soil biological activity in terms of CO2 evolution, dehydrogenase activity and nitrogenase activity, total bacterial count, total cyanobacterial count and total Azospirillum count. These increases were higher in presence of compost along with inoculation with cyanobacteria and Azospirillum in combination with all nitrogen levels than those inoculated with cyanobacteria and Azospirillum in combination with all nitrogen levels only. The superior results were due to the treatment received dual inoculation with cyanobacteria and Azospirillum along with 75 % N fed-1 in presence with compost that gave values for the tested parameters not significantly different than those achieved by the use of the recommended full dose of nitrogen. This means that dual inoculation with cyanobacteria and Azospirillum in presence of compost to barley plants cultivated in sandy soil; can save 25% of the nitrogen amount required for barley production
