Annual grasses with short seed viability compete with pastures, reducing productivity and quality. One control technique is cutting pastures for hay and silage, but it needs to be correctly managed to optimise effectiveness.
This module outlines how to optimise hay and silage production in order to extend the productive life of an established pasture.
Additional resources and further reading are available in the Materials tab.
At the completion of this module participants will be able to:
- understand how to preventing viable seed development
- understand how to physically trap and remove the seed in the conserved fodder
- identify the best timing for seed set control.
