This project aims to maintain the profitability of stubble retained systems by identifying key issues that are affecting the level of rofitability with growers, and then through utilising existing research and conducting locally specific trial and extension work assist growers to overcome these issues.
Key messages
• When dealing with annual ryegrass populations, it is a numbers game; the more you can control the better.
• Higher water rates in retained stubble resulted in increased efficacy of pre-emergent herbicides.
• Initial findings suggest that using speedtillers to retain stubble in the system does not result in any negative effects
