• Overall yield from May 17 sowing was impressive for this AgZone, at 1.6 t/ha.
• Delayed sowing by 34 days, to June 20, led to 1042 kg/ha less yield – 30 kg/ha/day.
• Short season hybrids could extend the safe sowing window later in this environment.
• Difficulty establishing canola in hot conditions could limit how far the sowing window can be brought forward.
• To take advantage of early autumn rains in this environment larger seeded broadleaf species that can be sown deeper should be tested.

• Yield were impressive; 1.9t/ha from April 26 and 2.2t/ha from May 17.
• Mid-season maturity varieties showed the greatest plasticity in plant development across sowing dates and may be a good option over a wide sowing/establishment period.
• Short season hybrids may enable the sowing window to be extended later with reduced risk.
• Long season varieties yielded poorly from these sowing dates.

• Yields were relatively stable across sowing times ranging from 2.2 to 3.1 t/ha.
• Early and mid-season hybrid varieties out-yielded the open pollinated varieties of the same season length.
• These hybrids combine early flowering, high biomass and in some cases a long flowering period.
• In general varieties had substantial plasticity and growers may be able to use a few varieties across a wide range of emergence dates; this is important if pre-ordering hybrid seed and/or dry sowing.

• 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.

• Over the longer term PBA Hallmark XT has outperformed PBA Hurricane XT and growers interested in IMI tolerant lentils are encouraged to try this variety on their farm

• Timely harvest can make a big difference to yields when lentils produce high biomass. • Over the longer term PBA Hallmark XT has outperformed PBA Hurricane XT and growers interested in IMI tolerant lentils are encouraged to try this variety on their farm

• PBA Hallmark XT – the new imi tolerant variety released in 2018 –performed well at Mingenew matching the yield of all other released varieties.
• Over the longer term PBA Hallmark XT has outperformed PBA Hurricane XT and growers interested in IMI tolerant lentils are encouraged to try this variety on their farm.

• One or two well timed fungicide applications increased yield 10% and full control a further 15%.
• Newer fungicides were more effective at supressing ascochyta but this did not translate to increased yield.
• Further testing of new fungicides is required in more locations and seasons.

 New variety Bilby  (breeding line 06204-16) out-yielded Carrolup (by 0.7 t/ha), but did not out-yield Williams , and had lower grain quality than Carrolup in grain quality. 

Similar to 2017, a mild finish to the growing season meant all varieties met Oat1 quality specifications, and agronomy had a reduced impact on grain quality.

 Kowari and Williams yielded similarly, and out-yielded newly accredited variety Bilby  (breeding line 06204-16) (by 0.15 t/ha) and Carrolup (by 0.25 t/ha).

Bilby was the most sensitivity to increasing nitrogen, with N increasing from 0 to 60kg N/ha significantly reducing Bilby’s hectolitre weight.

 New variety Bilby  (breeding line 06204-16) out-yielded Carrolup (by 0.3 t/ha), but did not out-yield Williams, and was between Williams and Carrolup in grain quality. 

Similar to 2017, a mild finish to the growing season meant all varieties met Oat1 quality specifications, and reduced the response of varieties to changes in plant density and applied nitrogen.

 

• Farmers can continue to use retained OP seed for at least three years.

• Lupin yielded 3.0 t/ha and canola 2.0 t/ha from late May emergence.
• Lupin gross margins were competitive with canola, and lupin gave the highest return on investment.
• For both lupin and canola variety selection was important, in particular Jurien lupin performed well from all sowing dates.
