The key objectives of this project are:
A: To determine if Linseed can be successfully grown under dryland farming conditions in the Great Southern region of Western Australia with the potential to scale up to commercial cultivation.
B: To determine if any investment is required into machinery and infrastructure by growers to grow linseed.
C: To develop basic agronomic guidelines to grow linseed in WA.
D: To assess the yield potential of two commercially available linseed varieties grown under dryland conditions in WA, Croxton and Bilney.
Over the three trial sites, the seeding rates and nitrogen application rates trialed did not consistently result in significant differences in grain yield or oil quantity and quality. Time of sowing had the greatest impact, with the earliest time of sowing generally resulting in higher grain yields. Glenelg on average had a higher grain yield and oil quantity, with Croxton having the highest oil quality.
