SF Calorific

SF Calorific is an outstanding new hybrid sweet sorghum ideally suited to fodder conservation.

Growing up to 3m tall, it has good grain content if allowed to mature for a late silage cut. Best suited to situations requiring maximum fodder yield from one or two large harvests, it is a late flowering variety with large broad leaves, maximising the leaf-to-stem ratio for improved feed quality.

Its high sugar content in the stem makes ideal for high yielding silage cuts. Under good conditions or irrigation, SF Calorific can be shut up for a second cut or grazed.

Seed Force is releasing SF Calorific in 2019, with small volumes available while it is being bulked up.
