The study investigated wheat response to phosphorus and potassium in saline-sodic field of Kohat, Pakistan. The K<sub>2</sub>O was applied at 0(K0), 75(K1), 150 (K2) kg ha<sup>-1</sup> as K<sub>2</sub>S0<sub>4</sub> and P<sub>2</sub>O<sub>5</sub> at (0(P0), 60(P1), 120(P2) kg ha<sup>-1 </sup>as (NH<sub>4</sub>)<sub>2</sub>HPO<sub>4 </sub>in three replications under two-factorial randomized complete block (RCB) design. Both treatments significantly enhanced wheat grain (118%) and dry matter yield (60%) at P2K2 compared to control. The P treatments significantly affected leaf P, Mg, SO<sub>4</sub>, Ca:P, SO<sub>4</sub>:P ratios and soil P, Ca:P, Cl:P and SO<sub>4</sub>:P ratios, while K on leaf K, Na, Ca, SO<sub>4</sub>concentration, K:Na, K:Ca, SO<sub>4</sub>:P,Ca:P ratios and soil pH, Na, K, Ca, SO<sub>4</sub> concentrations, SAR, Na:K, Ca:K and Na:Ca ratios. Leaf Na was decreased to 85.3 mmol (+) kg<sup>-1</sup> at K2 compared to 105.3 mmol (+) kg<sup>-1</sup>at P2K0. Negative correlation (R<sup>2</sup>=0.906) of leaf K:Na was found with Leaf Na concentration. Correlation of dry matter was more positive (R<sup>2</sup>=0.851) with leaf K:Na than grain yield (R<sup>2</sup>=0.392). It is concluded that K and P addition might be beneficial for improving crop nutrition and wheat yield in saline-sodic soils.</p>}, number={6}, journal={Bioscience Journal }, author={Hussain, Zahid and Khattak, Riaz Ahmad and An, Ping and Shao, Yang and Irshad, Muhammad}, year={2020}, month={Aug.}, pages={1867–1878} }
