Sowing early to maximise wheat yield on low fallow locations
Aims

To outline how farmers can maximise wheat yield on long fallow by sowing early with slow developing cultivars.

Key messages

Early sowing is essential in order to maximise yield of wheat crops grown on long (18 month) fallow. Long fallowing and early sowing are complementary practices, as the fallow reduces weeds and diseases which can be difficult to control in early sown crops, and early sowing with slow developing cultivars allows the crop to better use soil water that is stored during the fallow. Stored soil water also helps to establish early sown crops when there is minimal autumn rainfall. This fact sheet outlines how farmers can maximise wheat yield on long fallow by sowing early with slow developing cultivars, and is based on two years of GRDC funded research conducted by AgGrow Agronomy, CWFS and CSIRO in western NSW.
