The study included effect of combination to fertilizer nutrient solution and foliar application on plants potato in the developing sand culture system Randomized Complete Block Design RCBD were adapted this study 8 treatments of fertilizer. F0 without fertilizer, F1nutrient solution, F2 spray megafol activated amino, F3 spray magnum urea & phosphate, F4 spray agroleaf composite balanced, F1F2 nutrient solution + spraying megafol, F1F3 nutrient solution +spraying magnum and F1F4 nutrient solution + spraying agroleaf . L.S.D. were used to compare the means at 5% level of significances: - The results showed superiority of all treatments fertilizer (nutrient solution with the fertilizer) to the attributes under study compared with control treatment F0, treatment of F1F4 significantly increased number of stem, high of plant cm, leaf area Dcm2 and dry weight of shoots of sand culture reached 4.33 stem/plant ,61.67 cm ,97.35 Dcm2 , 30.40 g Compared with the control treatment. an‎d treatment F1F4 was significantly increased the yield of plant reached 672.00g and no significantly difference with F1F3, F1F2 treatments, while the ratio decreased in the F0 treatment reached 229.00g.
