Sowing serradella into sub-tropical grasses locations
Aims
  • To evaluate the performance of annual crop and pasture species sown into subtropical grasses.
  • To compare summer and winter sowing options to introduce serradella into subtropical perennial pastures.
Key messages

In this trial both summer sowing and conventional seeding after the break of the season resulted in the successful establishment of serradella into perennial grass pastures. All treatments resulted in serradella seed yields greater than 600 kg/ha, which has set them up for good legume regeneration in subsequent years. The yellow serradella experimental line (87GEH72.1a) shows considerable promise as a companion legume for perennial grasses in this environment. It flowers earlier than Margurita French serradella and has a hard seed breakdown pattern more suitable for summer sowing than current yellow serradella varieties (Yelbini*, Charano* and Santorini*).  Both summer sowing and conventional sowing of annual legumes into perennial grasses after the break require good weed control. Herbicide options and the impact of perennial grass suppression require further investigation. Weed seed set control in the year prior to establishment is recommended.
