In pot experiments with bread winter wheat varieties Astarta, Kyivska ostysta, Malynivka different conditions of mineral nutrition were created: 1) high background of mineral nutrition (N160P160K160 mg/kg of soil); 2) high background with foliar treatment with urea immediately after flowering; 3) low background of mineral nutrition (N32P32K32); 4) low background with foliar treatment with urea. It was shown that high background of mineral nutrition and foliar treatment with urea had a positive impact on the functioning of the photosynthetic apparatus, as well as on the productivity and protein content of wheat grain. The photosynthetic rate, grain productivity and protein harvest were the highest in plants of variety Astarta, but the grain protein content was some less. In terms of productivity and quality, Kyivska ostysta and Malynivka respond to the foliar fertilization with nitrogen better than Astarta. Plants that have been grown on a low background had lower values of photosynthesis, grain weight, protein content and harvest. Additional fertilizing with urea also had a positive impact in these conditions, but not enough to compensate for the lack of nitrogen in the soil.
