Abstract EN

Response of wheat to Azospirillum brasilense Sp-248 inoculation with different N-fertilizer levels using seawater irrigation was investigated.

All inoculated treatments increased plant height, shoot and root dry weight, and tiller number in compared with uninoculated treatments.

Yield parameters measured were also increased due to the inoculation.

In terms of the effect of saline irrigation, there were no significant differences in growth and yield parameters in plants treated with tap water and others irrigated with 8.0 % seawater concentration.

This would indicate a relatively high tolerance of A.

brasilense to saline irrigation and its ability to reduce the deleterious effects of saline on growth by increasing the plant’s adaptation.

However, increasing the seawater concentration in the irrigation water to 16.0 % significantly decreased all tested parameters.

Inoculation treatments generally increased NPKCa contents and decreased sodium ratio of the grains in compared with the uninoculated treatments.

Overall results clearly revealed that the Azospirillum inoculation saved about 20 units of N-fertilizer and that saving was made economically feasible by decreasing the chemical fertilizers needed, improving the nitrogen content and counteracting the effects of salinity.
