\textbf{Abstract}
\begin{abstract}
\normalsize{
Wheat (\textit{Triticum aestivum} L.) is considered to be the first strategic food crop in Iran. Drought can dramatically limit crop production and be threat to food security. Phosphorus helps crops use water more efficiently in a complete and balanced soil fertility program. Efficient use of phosphorus fertilisers is important from both an economic viewpoint and the conservation of the world's phosphate resources. To study the effects of foliar application of phosphorus on reducing the impacts of drought stress of winter wheat, an experiment was carried out at the research field of Yasouj Agriculture Research Station, Iran. The study was done in a split plot experiment based on Randomised Complete Block Design with three replications. Main plots included the levels of irrigation (1- control, 2- deficit irrigation from the stem elongation to booting stage, and 3- deficit irrigation from booting stage to the end of growth period) and five levels of phosphorus (P) foliar application were assigned to subplots (0, 3, 6, 9 and 12\,kg\,ha\textsuperscript{-1} KH\textsubscript{2}PO\textsubscript{4}). The results showed that the effects of different irrigation regimes and foliar application of phosphorus were significant on all traits, and its interactions were significant on plant height, number of grain per spike, biological yield and grain yield. Treatment of full irrigation and foliar application 6\,kg\,ha\textsuperscript{-1} P produced the highest grain and biological yield (6000 and 14170\,kg\,ha\textsuperscript{-1} respectively) and treatment of deficit irrigation from the stem elongation to booting stage without foliar application P produced the lowest grain and biological yield (2920 and 8219\,kg\,ha\textsuperscript{-1} respectively). Foliar application P effect was significant only in drought stress treatments and its effect was not significant in full irrigation treatment. Finally, foliar application of 9\,kg\,h\textsuperscript{-1} phosphorus decreased losses in wheat due to drought. }
