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

Ave. state oil% 2009-2013

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

Australian Quality 20 Year Trend

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

)

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%

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

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 to maximise yield and oil

Harvest management (northern NSW only)– Pattern of yield and oil formation– Plant population, hybrid vs OP, windrow vs direct
