Summer sowing serradella pod into perennial grass pastures locations
  • To evaluate the effectiveness of establishing annual legumes into established perennial grass-based pastures by 'summer' sowing of hard-seeded serradella pod.
  • To test the effectiveness of drilling pod versus broadcasting of pod.
Key messages
  • The results for summer sowing into an established perennial grass pasture were encouraging in a season with minimal spring rainfall. The results were negatively impacted by the low rainfall in spring. Drilling pod was more successful than broadcasting pod and then using animals to trample it into the soil.
  • This was the first summer sowing trial into perennial grasses in WA so it is too early to develop recommendations, but it appears that you need to use 20 to 40 kg pod/ha to achieve a good seedbank. The mid-March sowing time is at the end of the ‘sowing window’ for summer sowing. Sowing in early February is desirable to maximize the time for hardseed breakdown.
  • With summer sowing using pod rather than seed there is no need for de-hulling, so there is a cost saving per kilogram, but higher sowing rates are required as the seedlings need to compete with annual grasses, broadleaf weeds as well as the perennial grasses. The summer sowing method requires relatively high sowing rates and the concept relies to a large extent on farmers producing hard-seeded serradella pod on-farm at a low cost.After these promising results in 2010, similar trials will be undertaken in 2011 with local producers.
