Table beet in the process of growth forms a large volume of biomass, which causes its increased need for nutrients. As a result, during the growing season this crop requires a continuous supply of nutrients. Nitrogen consumption continues throughout the growing season, but the maximum shortage can occur during the phases of formation of a powerful leaf apparatus, root growth, so it is advisable to split nitrogen fertilization during the growing season, using fertilizer Nitriva urea. Both the lack of nitrogen and phosphorus reduces the attaining of high yields. With low application rates of complex fertilizers, phosphorus deficiency can be partially corrected by applying Apaliqua APP. In two-year studies held on a sod-podzolic soil in the Moscow region (Federal State Budgetary Scientific Institution «Federal Scientific Vegetable Center»), we studied the effect of foliar fertilization with Apaliqua APP complex fertilizer under various mineral nutrition systems developed by PhosAgro. In the experiments, phenological observations were carried out; the characteristics of crop development under various nutrition systems were evaluated. The day before harvesting, the biometric parameters of table beet were evaluated through the experimental treatments, and, based on generally accepted approaches, additional income from the use of fertilizers was determined when compared to the control treatment. The maximum increase in marketable root yield over control, on average for two years of research, was obtained in the treatment receiving N88P65K69(S5) with two Apaliqua APP N11P37 foliar applications and amounted to 8 t/ha. When reducing the total nitrogen rate by 16 kg/ha to N72P79K120(S20)+28СаО, the yield increase over control was 7,3 t/ha. On average for two years, the largest extra income was obtained in the N88P65K69(S5) treatment with two Apaliqua АРР foliar applications that amounted to 86 thousand rouble/ha, exceeding the other treatments by 12‒29 thousand rouble/ha.
