Better canola - crop archhitecture and seed quality locations
Aims
  • To evaluate the effect of row spacing (18, 22 and 30 cm) and target plant population (20, 40 and 60 plants/m2) on yield and oil content of a representative Clearfield® and TT variety.
Key messages
  • Widening row spacing reduced established plants per area for a given seeding rate.
  • At a yield of 1.5 t/ha there was no yield difference between 19 and 42 plants/m2 or between 18 and 30 cm row spacing in 2008 • At a yield of 0.44 t/ha the low plant population (28/m2) yielded best in 2009
  • In the Victorian Better Canola trial farmer-saved hybrid seed reduced crop uniformity (variable plant height), delayed maturity and increased blackleg infection
