abstract: Sweet sorghum is a multipurpose biofuel
feedstock that offers grain for human consumption, fodder
for livestock and ethanol for transportation purposes. The
knowledge on sugar components at different phenological
stages of crop growth and identification of appropriate
stage of harvesting is critical for sweet sorghum commercialization
and value chain sustenance. In this regard, sweet
sorghum stalk yield, juice yield, Brix%, pH, sugars
(sucrose, fructose and glucose) and their content were
analyzed at three different phenological stages i.e. the
dough stage, physiological maturity and post-physiological
maturity. Variations in sugar content at different growth
stages revealed that the sugar yield was high at physiological
maturity, but highest at post-physiological maturity.
Sucrose accounts for major fermentable sugar (about 70%)
and it sharply increased by 146% from dough stage to postphysiological
maturity. The variation in the monosaccharides
content (glucose and fructose) is not statistically
significant. This study points to the potential scope for
widening the harvesting window of sweet sorghum, by
cutting the stalks from physiological maturity stage and
beyond up to 15 days (post-physiological maturity), thus
helping the commercial distilleries by addressing a major impediment in sweet sorghum value chain. The entries SP
4495, SP 4511-3 and SPV 422 are suitable for harvesting in
a wider window of time as the sugar levels are sustained at
same level from physiological maturity to post-physiological
maturity.
