Increasing the profitability of the double break rotation in the medium rainfall zone of WA Wheatbelt through incorporation of an early sown high value pulse.

The objective of this trial is to 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.

This project will 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.

Investigating double break (or stacked rotation) options

In Western Australia, break crop options are currently limited and there is a high proportion of wheat and barley grown in rotation. Cereal crops account for 60-70% of paddocks sown in any one year, with the remaining area sown to a range of crop and pasture types including canola, lupin, clover, volunteer pasture, or left as fallow. In addition, there is an interest in chickpea and lentil to add a high value legume to the crop rotation. The application of these break crops is dependent on the grain price per tonne and on the level of severity of biological constraints present that lead to a reduction in grain yield and which varies from paddock to paddock. The use of a single break crop in rotation has been shown to be an effective tool in managing both weed and diseases that affect wheat production to remove biological constraints to crop production and allow the sustained production of cereal crops. However, with a change in resistance status of many common weeds and diseases, and a change in soilborne pathogens, a single break crop applied to a cropping system that is largely based on cereals has limited effect in reducing the biological constraints, with the longevity of the break crop benefit being reduced. Recent studies into the break crop benefits for highly herbicide resistant weed populations has found that a break of at least two years was needed to prevent grass seed set and substantially reduce grass seedbank numbers. 

Considering the high percentage of cereal crops grown in Western Australia, there is the need to evaluate the use of double break crop sequences to improve wheat grain yield and profitability. In particular, the Eastern Wheatbelt region has very limited break crop options, and there is the need to investigate the better use of tools such as fallow periods to improve break crop outcomes.

The pros and cons of using clearfield barley as a cover crop when sowing serradella pastures
  • Serradella is a useful pasture species on the sandy soils of the West Midlands. But it has two major weaknesses: weed control (particularly radish and capeweed) and a lack of early biomass production. By sowing serradella with a Clearfield Barley variety (Scope or Spartacus) and using Clearfield (Imidazolinone) herbicides both of these weaknesses can be overcome.
  • The aim of this demonstration was to highlight the pro’s and con’s of using Clearfield Barley as a cover crop when sowing serradella pastures.
