Abstract

This work represents a research of non-sugar matter (the content of α- amino nitrogen, potassium and sodium) in the root, and their effect on the recoverable sucrose quantity of three genotypes (Esprit, Belinda and Chiara) of sugar beet from vegetation areas of different sizes. They were grown by standard agrotechnical measures for sugar beet in the densities of 80.000, 100.000 and 120.000 plants per hectare. In 2005, the highest sugar utilization coefficient (12.94%) was achieved in the variant where plant density was 120.000 per hectare (0.083 m2) and the genotype was Esprit (N-type), which was 5.48% more than that in the variant with the lowest utilization coefficient (12.23%), where density was 100.000 per hectare (0.1 m2) and the genotype was Chiara (E-type). In 2006, the highest sugar utilization coefficient of 14.03% was achieved in the variant where plant density was 120.000 per hectare (0.083%) and the genotype Belinda (Z-type), which was 6.84% more than that in the variant with the lowest utilization coefficient (13.07%), with the density of 100.000 per hectare (0.1m2) and genotype Esprit (Ntype). In 2007, the highest sugar utilization coefficient of 14.27% was recorded in the variant with the plant density of 80.000 per hectare (0.125 m2) and the genotype Belinda (Z-type), which was higher by 8.26% as compared to the variant with the lowest utilization coefficient (13.09%), where density was 100.000 per hectare (0.1m2) and the genotype was Chiara (E-type).

Key words: Sucrose content, recoverable sucrose, alpha amino nitrogen, potassium, sodium, genotype, sugar beet.
