Abstract
Two varieties of wheat plants, i.e., Acsad 65 and Cham 3 were cultivated in
Deirezzor to Governorate study effect of applied different rates of nitrogen fertilizer on
the chemical and fertility properties of soil as well as the economical return of the
studied two grown varieties.
The obtained results showed that applying mineral fertilizer gaves areal increase
in the wheat yield, while this didn't occur when phosphorus was applied alone. Also,
increasing the rate of nitrogen fertilizer within the complete fertilization equation gave a
real increase increment in wheat yield reached of about 310.08 kg/donum in case of
Cham-3 as compared to the control treatment, while increasing nitrogen fertilizer rate
over the optimal limits didn't give any real increase in both of the studied wheat
varieties.
Response of Cham-3 to the increase of nitrogen fertilizer rates was clearly obvious
than of Acsad-65, as shown in treatment -3, where yield of Sham-3 reached 460.93
kg/donum.
It is noteworthy to mention that available nitrogen in the experimental soil
increased with increasing the applied nitrogen fertilizer rates, the reverse was true for
available phosphor, however its amount decreased with increasing nitrogen fertilizer
rates within the fertilizer equation.
