Summer sowing of hard seeded Serradella pod into perennial grasses locations
Aims

To evaluate effectiveness of ‘summer sowing’ hard-seeded serradella pod into established perennial grass pastures.

Key messages
  • Summer sowing into perennial grasses is showing some promise, but the results are inconsistent.  We need to develop guidelines for the required soil conditions (including soil fertility) and there is a need to reduce weed competition by controlling the seed-set of annual pasture weeds in the preceding year.
  • Results from these trials plus a range of other summer sowing sites demonstrate that serradella pods need to be drilled for successful establishment. Broadcasting pod is not a reliable alternative.
  • The experimental line of yellow serradella (72.1A) was slow to establish in the first year at Badgingarra but has has really gone ahead in the second year.  This yellow serradella is unique in having a very different hard seed breakdown pattern compared with the commercial yellow serradella varieties (i.e. Yelbini, Charano, Santorini) and is suitable for ‘summer sowing’.  It is earlier flowering (80 to 90 days compared to 105 to 115 for Margurita) and yellow serradella is hardier than French serradella.
  • Summer sowing using pod avoids the need for de-hulling, so seed is cheaper, but higher sowing rates are required.  Consequently the concept relies to a large extent on farmers being able to source or to produce their own hard-seeded serradella pod at low cost
