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 project 2015-2019 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 to maximise yield and oil Harvest management (northern NSW only) –Pattern of yield and oil formation –Plant population, hybrid vs OP, windrow vs direct head
