In order to determine the effect of the phosphoric element on the growth and development of potatoes, their productivity and efficiency, studies were conducted to determine the optimal nutrient medium in laboratory and field conditions. In nutritional variants with a concentration of P of 16 mg / l and 48 mg / l, the P content is higher than in leaves. In nutritional variants with a concentration of 48 mg / l, there is a smaller number of leaves compared to the 16 mg/l concentration variants and a delay in the flowering period. It was found that the nutrients contain important vital microelements in plant tissue and the output composition in variants of the concentration of P is 16 mg /l.
