The higher yield was obtained with combined P and K treatment under non-saline irrigation. Wheat yield increased by 14 and 7% with the application of 150 kg K 2O ha -1 and 120 kg P 2O 5 ha -1 over the control soil under saline irrigation. Potassium application significantly increased dry matter yield and root mass.

The P application had significant effect on the dry matter yield and other yield components. Results indicated that growth of wheat plants was impaired by saline irrigation resulting in a decreased grain and dry matter yield. Potassium and P fertilizers were applied at two levels. Wheat was grown in pots filled with saline-sodic soil which were irrigated either with normal or saline water. Therefore, the current study investigated the response of wheat ( Triticum aestivum L.) to saline irrigation water in saline-sodic soil supplemented with potassium (K) and phosphorus (P). Salinity-fertility interaction has not been properly explored especially in saline-sodic soils.
