Optimising management of early sown EGA Wedgetail locations
Aims

The aim of this series of experiments was to deterimine if management of EGA Wedgetail should be different to that of spring wheats sown in May, and if grown for grain only or dual purpose use.

Key messages

EGA Wedgetail can successfully be grown for grain only or dual purpose use and achieve yields competitive with recently released main season cultivars sown in May.  Growers wishing to graze EGA Wedgetail should use high plant densities (at least 100 plants/m2 on 305 mm row spacing, higher on narrower spacing) and some N fertiliser at sowing (particularly if soil mineral N is low) to maximise forage yield.  Gorwers who wish to grow EGA Wedgetail for grain only should defer N fertiliser application until after Z30 to reduce early vegetative growth.  Neither of these experiments or any others during the early sowing project have found a yield benefir from reducing plant populations, and target plant density should be kept at 100-150 plans/m2 (less on wide rows, more on narrow rows) in order to better compete with weeds.
