Effect of siazotrophs inoculation on performance of wheat plants amended with different levels of olive wastes

Abstract: A pot experiment was designed to monitor the response of wheat to inoculation with a mixture of Azospirillum brasilense and Bacillus polymyxa under different levels of olive waste water "0.0, W.W" at 1.0, 2.0 and 3.0% in absence of bacterial inoculation led to a significant decrease in all growth parameters e.g. plant hieght, No. of tillers, dry weight of shoots and roots and N-content of shoots and roots. Straw and grain yields as well as N-content were also reduced due to addition of olive wastes. On the other hand, inoculation of wheat with diazotrophs resulted in a significant increase in all wheat growth and yield parameters when compared to those uninoculated treatments. The highest straw and grain yield as well as N-content were obtained in plants inoculated with a mixture of Azospirillum brasilense and Bacillus polymyxa and fertilized with 1%O.O.W.W as an organic fertilizer could satisfy 25% of nitrogen requirements of wheat. Concerning the effect of diazotrophs inoculation in presence of olive wastes on total microbial populations in the rhizosphere of wheat, indicated that inoculation of wheat in the presence of olive waste has a stimulatory effect on total bacteria, fungi and actinomycetes in presence of olive wasres compared to uninoculated ones
