Pasture cropping lupins over subtropical perennial grasses locations
Aims
  • To evaluate the impact of crop seeding rate and perennial row spacing on grain yield of lupin crops.
  • To evaluate the feasibility of using tine seeders fitted with precision guidance technology to sow annual crops into subtropical perennial pastures (offset to perennial rows) without damaging the perennial base.
Key messages
  • Crop seeding rate and perennial row spacing both influence grain yield of pasture crops.
  • Lifting seeding rate of pasture crops might compensate for poorer establishment and, in turn, help to reduce any grain yield penalty.  For this experiment and assuming lupin seed is $300/t, lifting seeding rate by 50 kg/ha ($15) helped to avert a 26% yield penalty and proved to be $165/ha more profitable overall.
  • Where growers do not own a disc machine but have invested in precision guidance technology, with forward planning, it is feasible to use a tined machine to sow crops into perennial pastures without damaging the perennial base.
