Increasing the Profitability of the Double Break Rotation in the MRZ of WA Wheatbelt through incorporation of an Early Sown High Value Pulse

1. Demonstrate that growing canola (with effective weed control options) followed by a high value legume
(with higher economic value) can lead to an effective and profitable double break crop sequence. The
contribution of an early sowing date versus a traditional sowing date to increase the profitability of
these crops will also be evaluated.
2. Determine the economic value of growing canola followed by a high value legume, and the impact of
this rotation on the grain yield and profitability of a cereal crop in the first year following the double
break crop sequence.

Time to lime trial 96GE8 – Alan Desmond (now Tim Critch) Mullewa

In the mid 1990’s, DAFWA established a series of lime demonstrations sites across the WA wheatbelt, to highlight the importance of managing soil acidity. This trial is one of the series, which had a very simple design (0, 1 and 2t/ha applied, in 3 replicates). The rationale was to use farmer equipment, to enable larger areas to be treated differently, and ultimately provide extension opportunities across the WA wheatbelt.
