1) To see if matching canola and lupin variety maturity to sowing time would increase yields
2) To compare the time of sowing response of canola and narrow leaf lupin
• Lupin yielded 3.0 t/ha and canola 2.0 t/ha from late May emergence.
• Lupin gross margins were competitive with canola, and lupin gave the highest return on investment.
• For both lupin and canola variety selection was important, in particular Jurien lupin performed well from all sowing dates.

| Trial type | Experimental |
| Trial design | Randomised,Replicated |
| Sow rate or Target density | 1772 seed for canola |
|---|---|
| Sow date | April 11 dry, May 5 dry and May 25 |
| Harvest date | Unknown |
| Trial design method | RCBD Randomised Complete Block Design |
| Plot size | 18m x 1.54m |
| Plot replication | 4 |
| Plot blocking | yes |
| Plot randomisation | Y |
| Other trial notes |
The results of this trial are atypical of time of sowing responses observed in the Northern Agricultural Region. They highlight how important spring conditions and stored soil moisture are in determining the productivity of late emerging crops. Both lupin and canola were profitable from the first two sowing dates and it was interesting to note that lupins gave the highest return on investment. |
