The development of vegetable growing in our country is aimed at fully meeting the needs of the population in vegetables and is based on the use of a certain level of production intensification. Carrots during the growing season require a continuous supply of nutrients. At the beginning of growth, it is particularly demanding for nutrients in a highly soluble form. At this time, the plant consumes the most nitrogen. During the growth period of root crops, the need for phosphorus and especially for potassium increases. In two-year studies (2019–2020) on sod-podzolic soil in the Moscow region (Federal state budgetary scientific institution «Federal Scientific Vegetable Center»), we studied the effect of foliar top dressing for vegetation with Apaliqua APP complex fertilizer on various mineral nutrition systems developed by PhosAgro. Humus matter – 1.54%, pHKCl – 6.1 and 6.63, content of mobile forms of P2O5– 437 and 199 mg/kg of soil, K2O – 220 and 211 mg/kg of soil in 2019 and 2020, respectively. In the experiments, phenological observations were carried out, the characteristics of the development of vegetables under various food systems were evaluated, the day before harvesting, the biometric indicators of carrots were evaluated according to the experimental variants. Guided by generally accepted methods, additional income from the use of fertilizers was determined according to the control variants. The maximum increase in commercial yield in comparison with the control, on average for two years of research, was obtained in the variant N92P76K69(S5) with the use of four Apaliqua APP top dressing N11P37 and amounted to 8.7 t/ha. When reducing the total dose of nitrogen by 35 kg in the active substance to N57P90K120(S20)+28СаО, the yield increase to the control was 5.6 t/ha. On average, for two years, the largest amount of conditional net income was obtained in the variant N92P76K69(S5) with the use of four Apaliqua АРР top dressing and amounted to 83 thousand r/ha, which exceeds the other variants by 35‒36 thousand r/ha.
