Evaluation of sub clover varieties in a cropping system locations
Aims

To evaluate sub clover varieties in a cropping system.

Key messages
  • At both sites Antas sub clover (Brachycalnium type) grew significantly more DM than other sub clovers - over 300% increase in dry matter on its nearest competitor at Mininera and 180% at Dunkeld.
  • The more biomass you grow, the more nitrogen you fix. Using rules of thumb (25 kg/ha N per 1 t DM).
  • Generall speaking earlier flowering varieties will grow more dry matter early, while later flowering varieites will make the most of late rains. In practice a spread or mix of flowering date may be prudent in a paddock situation.
  • More work is required to show possible yields, both as monocultures and as mixes for rotational purposes.
