Abstract
The purpose of this article was to determine the effectiveness of phosphorus fertilizers in vegetable and potato crop rotation. Provides high and high yields with the use of 100 - 140 kg / ha of phosphorus fertilizers on the background of N200K90 in vegetable growing. The NKFU's reliably complementary crop, used as phosphorus fertilizer, is about 140 kg / ha in the onion crop, although it is consumed at the rate of R2O5 per hectare in white cabbage, potatoes and sweet peppers.
