Table S1.
Biomass and grain yield of intercropped maize and faba bean with and without root barriers under field conditions (field study 1)
| N application (kg ha−1) | Faba bean | Maize | ||||||
| Biomass (kg ha−1) | Grain yield (kg ha−1) | Biomass (kg ha−1) | Grain yield (kg ha−1) | |||||
| Barrier | No barrier | Barrier | No barrier | Barrier | No barrier | Barrier | No barrier | |
| 0 | 5.77a | 7.81b | 3.96a | 6.39b | 6.70a | 6.37a | 6.47a | 6.98a |
| 150 | 5.77a | 7.40b | 4.22a | 5.69b | 10.54a | 9.61a | 11.99a | 10.77a |
Values for grain yield are averages of 2 y (2006 and 2007). Values in the same row followed by different letters are significantly different (P < 0.05).
