Summary

This field trial demonstrates that seed adaptation to cropping system type significantly influences performance in mixed cropping arrangements. Whilst mixed cropping showed neutral or beneficial effects on yield depending on species combination and drought conditions, wheat–lupin mixtures performed best for yield and drought resistance, whereas wheat–lentil combinations underperformed. The findings support the insurance hypothesis that diverse cropping can stabilise yields when individual crops experience stress, though species selection and seed genetics are critical to realising these benefits.

UK applicability

The findings on cereal–legume mixing and drought resilience are relevant to UK arable farming given increasing climate variability; however, the specific species combinations tested may require adaptation to UK growing conditions and soil types. Future UK research would need to validate these results under British climatic and edaphic conditions.

Key measures

Above-ground vegetative biomass, seed yield, harvest index, drought resistance (early-season and late-season drought treatments versus control)

Outcomes reported

The study compared crop yield, above-ground biomass, harvest index, and drought resistance in four cereal–legume mixed crop combinations (wheat and oat with lupin and lentil) versus monocrops, using seeds adapted to either monoculture or mixed cropping systems under control and drought conditions.
