- •
Four species mixtures achieved large yield advantages (+31%) over monocultures.
- •
Seasonal asynchrony in growth of mixed species contributed to this yield advantage.
- •
Different foliar architecture of mixed species did not explain this yield advantage.
- •
Light interception was nearly complete in monoculture and not enhanced in mixtures.
- •
Temporal rather than spatial shoot complementarity benefits productivity of leys.
