Abstract
The article presents data on the change in the accumulation level of the sum of chlorophyll a + b, flavonoids and the nitrogen status of plants in a five-field grain-coupled crop rotation with different doses of organic, organomineral and mineral fertilizers. The revealed patterns of changes in the level of nitrogen nutrition of plants allow us to conclude about the positive effect of the aftereffect of organic fertilizers only in soft winter wheat and corn in the Belgorod region. The difference between the doses of mineral and organic fertilizers is significant only in the case of wheat. Increased doses of mineral fertilizers lead to a cumulative accumulation of nitrogen in the soil and, as a result, a decrease in nitrogen status in plants.
Keywords: Nitrogenous nutrition, wheat, sugar beet, barley, corn, chlorophyll, flavonoids, photometric express diagnostics, five-field crop rotation.
