This article covers scientific research to determine the effect of mineral fertilizers and agrotechnical measures against pests found in the cabbage agrobiocenosis. The distance between rows is 70 cm, the distance between nests is 30 cm, the number of seedlings in each nest is 476 (4760 per 10 ha) plants per 1 ha. White cabbage is fertilized twice on the study site. For feeding cabbage, 2 kg of nitrogen, 1.5 kg of phosphorus and 0.7 kg of potassium are added per 1 square meter. On gray soils, it is recommended to water cabbage 8-10 times, and on sites with surface water - 6-8 times. It was studied that the effect on harmful organisms found in the cabbage agrobiocenosis can go in two different directions.
