Sugar beet is a crop that transforms a large amount of the Sun skinetic energy into organic matter energy (over 100,000 Kj/ha by sugar alone). This is why this plant is considered one of the most intensive crop species in the production region. Successful sugar beet production requires that the full set of cultural practices along with optimum fertilizer application be employed. In our study, the yield increased up to 15 kg/ha of added nitrogen, 100 kg/ha of added phosphorus, and 50 kg/ha of added potassium. The sugar percentage decreased with increasing nutrient quantities, as did the yield of sugar. The largest sugar yields were obtained in the nitrogen treatment with 100 kg/ha, phosphorus treatment with 100 kg P2O5/ha, and potassium treatment with 50 kg K2O/ha. These results clearly show that nutrient deficits and nutrient surpluses both have the same, negative effect on yield.
