The results assessed from sugar beet microtrials at Kljajicevo (Serbia) in
2010 harvested at three harvest periods demonstrated that the average root
yield tended to increase from the first to the third harvest period. The
average increase in root yield between the first and the second harvest
period was 29.06 t ha-1 or 32.76%, between the second and the third period
14.77 t ha-1 or 12.54% and between the first and the third period 43.83 t
ha-1 or 49.40%. In average, the content of sugar in root showed a similar
tendency. The highest increase in this parameter was registered between the
second and the third harvest period and it amounted to 1.00% abs. Other
indicators of sugar beet processing quality showed a slow increase or slight
decrease depending on the harvest date, probably due to plentiful rainfall in
September. Mean granulated sugar yield had an increasing tendency: 3.413 t
ha-1 or 32.82% between the first and the second harvest period, 2.820 t ha-1
or 20.42% between the second and the third and 6.233 t ha-1 or 59.94% between
the first and the third period.
