The project commenced in 2012 to establish two fertiliser trial sites at a dryland and an irrigated lucerne seed production paddock. The initial project was funded for three years. Additional funding was granted to extend the project for a further two years (2015-16 and 2016-17) at the irrigated site.
The project aimed to provide a clear picture of determining what fertiliser products would deliver the maximum benefits for lucerne seed producers with the primary focus on seed yield. The lucerne seed industry would benefit by being able to cost-effectively fertilise lucerne for seed crops, thereby finding the optimum investment level of fertiliser applications required to maximise seed yields and gross margins.
