In the technology of cultivation of sugar beet the significant role is allocated for system of fertilizer. The research problem included studying of influence of various norms and combinations of mineral fertilizers on productivity and quality of this culture. In 2012-14 the stationary field experiment with sugar beet of a grade of "Nero" on an experienced field of department of agrochemistry in educational economy "Kuban" was put and made. Studying of the nutritious mode of the soil is one of the most important questions of determination of effectiveness of fertilizers. Researches showed that the application of double doses of nitrogenous, phosphoric and potash fertilizers, and also the complete fertilizer in double and threefold dose on the chernozem lixivious, has essential positive impact on the maintenance of like elements of a mineral delivery, providing the favorable food mode during body height and cultural development. Fertilizers promoted more intensive intake of nitrogen, phosphorus and potassium in plants of sugar beet. The maximal maintenance of these elements is observed in a phase of clamping of rows. In experience the good harvest of sugar beet was received. Average productivity made about 450 c he (the increase makes ot13,6% to 77,4%). The maximal productivity of root crops is received at importation of N80P80K80 and N120P120K120 also made 620,3 and 633,3 c/he. Our researches showed that sugar content of root crops by options of experience
fluctuated from 14,0 to 18,7%. The best results are received in options with importation of N80P80K80 - in these options sugar content made 18,7%.Thus, optimum conditions for sugar beet are created at importation of the complete mineral fertilizer at the rate of N80P80K80
