Sugar Beet Root Development with Different Nitrogen Fertilization Rate
2017
Varga I, Antunovic M, Iljkic D
The aim of this study was to analyse sugar beet root growth during 2014 vegetation period at two different nitrogen fertilization rates N1 = 45 kg/ha N and N2 = 99 kg/ha N. The sugar beet plant samples were collected in 12 terms from the end of May to the second half of September. During each sampling the total of 10 individual plants were analyzed. Fresh sugar beet roots were weighted and root diameter (cm), number and distance between the cambium rings (cm) were determined. The average share of root crown in the whole root mass was around 33% as of 20th September. The different nitrogen rates did not have a significant impact on the observed parameters and as of 20th September the average sugar beet root mass was 1782.8 g/plant, the root diameter was 13.1 cm and there were on average 8.2 cambium rings in a root.
