Subzero is a hybrid brassica which provides greater flexibility in sowing and a significantly greater forage yield per annum than other rapes. Subzero can be sown in spring or autumn with potential to carry through to winter. Subzero has a very rapid regrowth potential under suitable conditions combined with its ability to carry through to winter, makes it the premier cultivar of its type. Subzero has excellent regrowth after frequent grazings,
making it one of the most persistent forage brassica cultivars while retaining leaf and stem quality with active regrowth throughout cool seasons, including frost periods.
Subzero sown in autumn can be utilised throughout the year, due to its cold tolerance, high production and palatability can be kept for winter grazing with more reliability than many other forage brassicas.
