IN the northwest Victorian region, farming is a constant balancing act, managing profitability, soil health, feed availability and soil cover.
And within this complex system, the growing use of break crops is helping significantly break the traditional cycle.
And Mallee Sustainable Farming research and trial work is showing break crops are fast proving to be more than just a gap between cereal rotations.
With smart management, they can enhance resilience, diversity in income streams, and help farmers tackle the variability of each year.
Why break crops matter in the Mallee
BREAK crops in the Mallee are typically legume crops or pastures – or less commonly – canola, grown in rotation with cereal crops such as wheat and barley.
It is well known break crops offer a range of agronomic and practical benefits such as disease and weed control, N fixation (legume only), soil moisture conservation from early termination and high-quality feed.
However, like all farming, break crops are not without their challenges, particularly in low rainfall zones.
Yields can be variable, and early sowing of some crops (such as field peas) can increase disease risk.
Market uncertainty and poorly matched varieties can also impact returns. Despite this, with careful planning and good agronomy, the benefits can outweigh the risks.
More than just a break – a flexible farming tool
WHAT makes break crops especially relevant in the Mallee today is their versatility. In an environment where conditions can shift quickly, having options is essential. Break crops can be:
• Grazed early to fill autumn feed gaps
• Cut for hay if the season turns dry or feed demand spikes
• Taken through to grain if seasonal conditions are favourable
This flexibility supports more resilient mixed farming systems. In short, break crops are no longer just a rotation tool for the next cereal crop, they’re a strategic choice for managing risk, supporting livestock, and adapting to the season as it unfolds.
What’s the opportunity for grazing break crops in the Mallee?
WHILE much of the existing research has focused on the benefits of break crops for the following year’s cereal yield, less is known about their role in directly addressing early-season feed shortages, particularly in low rainfall zones such as northwest Victoria.
That’s where the MSF Intern Research Project comes in.
This trial is exploring how different break crop species, when sown early and strategically managed, might help fill the autumn feed gap and reduce reliance on costly supplementary feeding.
Key questions being investigated:
• Can break crops deliver early-season biomass and nutrition for livestock compared to traditional regenerating pastures?
• Which species perform best in the Mallee’s dry conditions and produce the earliest feed?
• How well do different crops recover after grazing?
• Is there potential for multiple grazing events in a single season?
• Benefits to the subsequent crop, particularly through improved weed control and soil moisture conservation.
Unlocking potential: comparing pulse, cereal and mixed break crops
AS part of the trial, a pulse-based break crop is being compared with a mixed cereal–pulse options and cereal forage crops all suitable for grazing.
This comparison will help answer key questions around early feed, recovery after grazing, and benefits around weed control and soil moisture conservation in the following crop.
It will also be particularly valuable in looking at how each option performs after the dry autumn conditions.
What’s next?
WITH establishment counts beginning, the next phase of the project will focus on monitoring biomass production and post-grazing recovery.
Simulated grazing will be used to assess how different break crop species respond to grazing or whether these crops should be left for a hay cut.
