Nutritional regime of leached chernozem and leached leaves in various agricultural techniques of cultivation of sugar beet hybrids in the Central Chernozem Region

The influence of tillage, sugar beet hybrids and fertilizers on the nutrient regime of leached chernozem and leaf diseases was studied. It was found that the soil was more abundant in N-NO3 when cultivating the hybrids RMS 127, P2O5 and K2O – hybrid RMS 120. The content of N-NO3 in the soil was higher with no-tillage, and the content of P2O5 and K2O was higher with multi-depth treatment by 10–40%. The lesion of the leaves depends on the disease and the agricultural technique of cultivation. The highest yield of domestic hybrids (40.0–41.6 t/ha) was observed with combined treatment with fertilizers, and foreign hybrids (46.0 t/ha) with multi-depth dumping. The sugar harvest amounted to 7.2–7.5 t/ha for the cultivation of domestic hybrids, and 8.4 t/ha for foreign hybrids.
