## In short

The turnip-pea intercrop is treated as a whole system whose combined yield is compared against its parts grown apart, with the interspecies relationship between the two crops driving the emergent gain.

## What they found (results)

A 50:50 turnip–pea intercrop produced higher combined hay and protein yield (8.28 t/ha hay, 1.78 t/ha protein) than either crop grown alone, with a land-equivalent ratio above 1.0, meaning the combined system used land more efficiently than growing the species separately.

These researchers were not testing DSRP. The finding is theirs; the correspondence to DSRP is drawn by this site.
