In the conditions of the Republic of Belarus there was studied the influence of conditions of mineral nutrition on content and carry-over of nutrients (plant nutrient depletion) of white cabbage (Brassica oleracea convar. capitata var. alba L.) of an early maturity group growing cultivated cassette seedlings. There were established parameters of the specific carry-over of nutrients, which could be used for calculating doses of nutrients under the planned yield of white cabbage of early maturity group. In case of the highest yield of cabbage of 45.0 ton/ha (hybrid Ilaria F1) and 87.6 ton/ha (variety Zhnivenskaya), the specific carry-over of nutrients with 10 tons of main products was respectively the following: nitrogen – 14.4 and 15.2 kg, phosphorus – 8.2 and 7.3 kg, potassium – 25.1 and 31.4 kg. The obtained experimental data of the influence of earliness of ripening of varieties and hybrids of early cabbage and doses of mineral fertilizers on specific carry-over should be used for forecasting productivity in the process of cultivation of early cabbage.
