%X Sweet sorghum is a C4 crop with high photosynthetic efficiency with a unique
ability of high carbon assimilation (50 g m-2 day-1) and accumulates high
concentrations of easily fermentable sugars (glucose, fructose and sucrose)
in the stalks. Hence, it is widely believed that it is an alternate energy source
that is renewable, sustainable, efficient, cost-effective, convenient and safe to
use. Sucrose is the major sugar in sweet sorghum juice which constitutes up
to 85% of the total sugars (Woods 2000). The sugar yields ranged between
1.6 to 13.2 Mg ha-1, with significant variations observed between years and
regions (Jackson et al. 1980; Reddy et al. 2007; Zhao et al. 2009). The juice
sugar content is dependent on the crop stage, because fructose is more
abundant at the early development stage, whereas sucrose tends to be
dominant after heading (Sipos et al. 2009). The sweet sorghum juice sugar
content ranged from 10 to 25 Brix% at maturity (Reddy et al. 2007; Ritter
et al. 2004). Research at the International Crops Research Institute for the
Semi-Arid-Tropics (ICRISAT) showed that sweet sorghum juice yield ranges
between 16.8 to 27.2 m3 ha-1 (Reddy et al. 2007) and accrues about 23%
additional returns vis-à-vis grain sorghum (Rao et al. 2009).
