Cane juice quality and sugar yield
Sugarcane juice quality parameters like brix (%), pol (%) cane, purity (%),
-1
recoverable sucrose (%) and sugar yield (t ha ) were not significantly in 2008-09 and

2009-10 (Table 5). The brix (%) ranged from 21.50 to 23.03 and 16.33 to 18.30 in 2008-
09 and 2009-2010 seasons. In case of pol (%) cane ranged from 15.34 to 16.07 and

11.10 to 12.88 in 2008-09 and 2009-10 seasons. The purity (%) ranged from 88.62 to
91.68 and 85.89 to 88.95 in 2008-09 and 2009-10 seasons. The recoverable sucrose (%)
ranged from 12.55 to 13.57 and 9.10 to 10.38 in 2008-09 and 2009-10 seasons. Sugar
