Geometric uniformity improves yield of canola and lupin locations
Aims

To determine if spacing lupin (Lupinus angustifolius L) and canola (Brassica napus) plants in more uniform geometric patterns can improve yield of these species in the Northern Agricultural Region of Western Australia.

Key messages
  • Canola yield increased up to 17% when plants were spaced evenly apart compared to the spacing observed in commercial paddocks.
  • Lupin yield improved up to 7% when plants were spaced evenly apart, but this was not statistically significant.
  • Moving towards improved plant spacing without achieving perfect spacing is likely to improve yield.
