- Intervention effect Grain yields of cover crops in mixed drill rows were similar to crops grown without pasture species.
- Intervention effect Alternate drill rows reduced cover-crop grain yields by an average of 24% relative to mixed drill rows.
- Observation Canola and lupin crop biomass was lower than wheat and barley biomass.
- Recommendation Canola and lupin should be used more as cover or companion crops in semi-arid environments.
- Intervention effect Pasture yields beyond year 1 were reduced by about 20% in alternate drill row treatments compared with mixed drill rows, with greater differences in more favourable conditions.
- Observation Yield reductions in lucerne were concentrated in the fewer drill rows of the alternate configuration.
- Intervention effect The alternate drill row configuration increased subterranean clover abundance in year 1.
- Observation Subterranean clover remained a minor component of all swards beyond the establishment year.
- Observation Grain size was smallest where previous pastures contained lucerne and subterranean clover without phalaris.
- Observation Protein concentration in grain was highest where previous pastures contained lucerne and subterranean clover without phalaris.
- Observation Spatially separating species in drill rows at sowing gave little advantage in total productivity.
