Abstract
A factorial greenhouse pot experiment was carried out at Fac. Agric. Kaferelsheikh,Egypt in winter season to investigate theefficiencies and quantitative relations of the added N fertilizer (0, 30, 60 and 90 kg N/acre) and soil – N on wheat yield wheat crop was irrigated with tap water (Wo) and three artificial saline water(W1,W2 and W3) with three levels of salinity(C1,C2 and C3)for every one. All treatments were replicated three times. The results can be summarized as following: - The calculated grain yield when no fertilizer added, was decreased when salinity levels and sodicity of irrigation water increased . - The maximum yield was decreased when salinity level of irrigation water increased. - The maximum addition of N fertilizer decreased due to increasing salinity and sodicity of irrigation water. - The useful of soil – N was decreased when salinity level of irrigation water increased and also with the type of irrigation water according to the following order: W0 > W1> W2 >W3. - The efficiency of added – N fertilizer decreased when added N levels increased while this efficiency increased as salinity levels of irrigation water increased. - The contribution of N – fertilizer in yield production was increased when salinity levels of irrigation water increased. On the other hand, the contribution of soil - N was decreased when salinity and added N increased. As the fraction of added Nfertilizer increased the fraction of soil - N decreased with the same ratio.
