Presentation Transcript

  1. Canola quality issues and future R&D focus Don McCaffery Technical Specialist NSW DPI Orange Presentation title – Presenter name(s) – Division – Date

  2. Canola oil quality challenges • Seasonal variability • Spring moisture stress and/or heat during podfill • Yield, oil % • Weather damage • 2010 – wet harvest – low test weights • 2013 – frost

  3. Ave. state oil% 2009-2013

  4. Grower objectives • Weed control • Yield • Rotation & system fit • root & crown disease control • maturity for operational & harvest efficiency • Oil content - only quality parameter paid for • no payment for protein • oil inverse relationship with protein

  5. Australian Quality 20 Year Trend

  6. Yield vs oil in profitability • @ 2.0 t/ha @ 42% oil @ $500 t/ha = $1,000/ha gross • Increase yield by 5% (no extra oil) = $1,050/ha • Increase oil by say 3% (no extra yield) = $1,023/ha • 5% yield is a lot easier to achieve than 3% oil • Highest oil lines currently are RR • Standard and high oleic specialty types

  7. National Variety Trial 2013 Example

  8. Nitrogen effects on yield and oil • Single most important nutrient in canola productivity

  9. Specialty – high oleic/low linolenic • Market driven • 3 crushers, 2 seed companies • MONOLA and Victory lines • Demand ?..... Growing • Currently 5-6% • Quality (fatty acid content) apparently stable across environments • 2013 tests on NVT line • Oleic acid content • Bellata 66.5%; Condo 67.3%; Lockhart 66.9%

  10. Recent and future research • Targeting yield, not specifically targeting oil content or quality parameters • Agronomy/VSAP projects • Quality data collected on a range of agronomic experimental treatments • Variety-hybrid, sowing time, plant population, crop nutrition (mostly N), row spacing • National Variety Trial data since 2005

  11. New canola physiology-agronomy project2015-2019 • Across 3 states – NSW, Vic and SA (similar in WA) • Physiology/modelling and tactical agronomy trials • 5-6 sites in NSW + phenology • Assessing early sowing tomaximise yield and oil • Harvest management (northern NSW only) • Pattern of yield and oil formation • Plant population, hybrid vs OP, windrow vs direct head
