Nitrogen rates and NPK ratios applied in the study had different effects on total nitrogen and nitrate contents in the laminas and petioles of the studied sugarbeet genotypes. Amount of nitrates, especially in the petioles can be considered the most reliable indicator for determining sugarbeet plant supply with nitrogen. Differences in nitrate content found among the genotypes indicate the necessity of knowing the genetic specificity in nitrogen nutrition for individual genotypes
