Effect of inoculation with local isolates of Azospirillum spp. and nitrogen Fertilizer in some specific qualities of wheat plant Triticum aestivum L.


A field experiment was conducted to study the infleunce of the role of inoculation with Azospirillum SPP and different levels of nitrogen (0, 0.25, 0.5, and 0.75) of previously recommended nitrogen fertilizer, and the concentration of some elements in the soil of the wheat plant Triticum aestivum L. The nitrogen-stabilized isosperm bacteria was isolated from soil, where previously okra and maize grown on. They symbolized as A3, A2, A1, in addition to the comparison treatment symbolized A0. The results of the field experiment showed that the isolation of isolates was greater than that of the isolates. The results showed that A3 isolation was superior over A1 and A2 isolates in most detected traits. Since it gave the highest nitrogen, phosphorus and potassium levels were recorded at 50% of flowering (2.91, 0.747, 2.33%, respectively). Recorded nitrogen levels was higher with wheat, as compared to other crops. The results showed that the concentrations of nitrogen, phosphorus and potassium  of N3 treatment were higher than the others at the end of the experiment (2.72, 0.810, 2.84%). The interaction between Azospirillum SPP and N3 gave the highest values in all studied traits. Interference between isolation A3 and N3 was highest in protein (20.80%).
