Soluble solids content of cultivars of sweet and forage sorghum
juices in the first week post-anthesis was around 8 ◦Brix and
increased 2 ◦Brix in the next three subsequent weeks, reaching
the optimum level after the fourth/fifth weeks. The principal sugars
found in juices were glucose, fructose and sucrose. Rio and
Della were the highest in total sugars with 112 and 102 g L−1 juice,
respectively. The highest production of ethanol per hectare per cut
(1051–924 LHa−1) was for the sweet sorghums (Della, M81E and
Rio) whereas the two forage sorghums (Tato and Thor) only yielded
approximately 770 LHa−1.
