Influence of fertilization and nitrate-nitrogen position in soil profile on the sugar beet root yield and quality

Researches, which have lasted for two years, were carried out on long-term trial field at Rimski Sancevi, near Novi Sad (Serbia). In this trial the eight fertilization variants of N, P2O5 and K2O increased amounts were studied. Sugar beet root and tops yields were determined, as well as the elements of technological sugar beet root quality. Based on these results, percentage of sugar utilization and refined sugar yield was defined. In the spring, before applying of N fertilizer, amount of nitrate nitrogen in the soil and its influence on yield and quality was determined.
