A useful article for growers that looks at selecting a suitable sorghum variety and includes a case study on growing forage fast.

 

This article looks at selecting a suitable sorghum variety and focuses on the northern VIC & southern Riverina NSW areas.

“The most commonly available are sorghum x sudan grass hybrids which are lower in prussic acid than traditional straight sorghum varieties. This creates a plant with a higher stem to leaf ratio and lower prussic acid levels allowing it to be grazed at 650 to 800mm high for optimum quality. This is earlier than original varieties, which were suitable for grazing at 800 to 1200mm high.

Other aspects to consider are the maturity of the variety and whether or not it carries the Brown Mid Rib (BMR) gene.

Maturity or flowering date is the main driver behind a varieties speed of establishment and time to first grazing. If a grazing system requires a quick bulk of feed then an early maturing sorghum x sudan such as FeedEx forage sorghum is an excellent option.

If a later maturing, lower fibre, highly digestible summer forage is more suited to your system a variety carrying the BMR gene would be more suitable.”

This article also includes a case study titled ‘Growing forage fast’ that looks at FeedEx forage sorghum.
