A 2-factor field experiment was conducted on wheat (Triticum aestivum cv. Giza 168), 2016/2017, grown on a Torripsamment sand soil in Ismailia, North of Egypt to assess K and ascorbic acid  (AA) application. K treatments were K₀ none, K₁ through the soil at 200 kg K ha^-1, K₂ foliar spray with1000 mg K L^-1 solution and K₃ through soil + foliar. Ascorbic acid (AA) spray treatments were A₀ none, A₁ spray with  100 g L^-1and A₂  200 g L^-1. Fertilization showed the positive response for yields (grains and straw) and NPK uptake in plant reaching highest by treatment of K₃A₂. Grains in the non-fertilized yielded 2.26 Mg ha^-1 increasing to 13.7% by  K₀A₁ and  119% by K₃A₂. Same two respective treatments showed grains uptake of 24.5 and 219% for N; 8.6 and 34.6 % for P and 18.2 and   367% for K.
