To balance between maximising production, through the application of nitrogen, and quality, where one of the marketing factors is the level of soluble sugars, which are reduced through the application of nitrogen.
To provide herbicide alternatives to Lontrel, that has been prohibited from use in export oaten hay crops due to residual presence of the herbicide in the stems and leaves.
To provide best bet variety options.
Key messages
Hay crops can be used for both risk management and as part of an integrated herbicide resistant grass management program.
Paddock selection is important. It is best to select a paddock with a low weed burden; there are limits to the amount of ryegrass that is accepted for export oaten hay.
For quality oaten hay it is important to minimize stem thickness; this can be achieved by the use of high seeding rates. Cross sowing may be necessary to ensure windrows are supported by stubble for bailing, especially if sowing using wide row spacings.
