Experimental data obtained from the application of commercial fertilizers have been summarized and are presented in tables. Experiments were carried out in sod-gleysolic loamy sand soil. Growing nitrogen rates (N60, N90, N120, N150) have been studied depending on the level of phosphorus and potassium fertilizers (P90 K90, P120 K120, P150 K150). The influence of fertilizers on potato yield and quality indices has been analysed, the economical effect of the obtained results has been estimated. It has been found that the best agronomical and economic effect under definite soil and climatic conditions is ensured by the fertilizer rate of N120 P90 K90.
