Traditionally ANZAC day marked the date on which growers in Western Australia would start dry seeding.
This page contains information on the optimum sowing windows to maximise grain yield of canola, for 24 locations, three soil types and three canola cultivars, obtained from the APSIM-Canola model a
Looking at past years of rainfall does not guarantee that the rainfall trend will continue into the future but it can give us some idea of what might happen.
Yield was highest from earlier sown plants; mid-May sown plants yielded only 18% of those sown in mid-April.
How late is too late to sow canola? What is the yield penalty from time of sowing (TOS) or late sowing? What is the estimated yield loss from delayed sowing of canola in WA?
The barley module of Flower Power is a statistical model to predict the date of awn emergence (Z49) in Western Australian environments.
With so many new wheat varieties out there, you may be scratching your head over which variety to choose for next season.
Delayed seeding or emergence will shorten the growing season for wheat, reducing yield potentials.
Early sowing is the key to maximising canola yield in the northern region;
Delaying sowing by 15 days after 31 March led to 195kg/ha less yield – a loss of 13kg/ha/day
Canola yields were above 2.5t/ha from low plant density (10 plants per square metre).
Spacing plants more evenly did affect some aspects of plants growth.
