a
Environments are described by a sequence of codes: 0i, 2i, and 5i denote the number of irrigation cycles; B/F denotes whether the planting system was “bed” (B) or “flat” (F); N/H denotes whether planting date was normal (N) or late (H, simulating heat); Z indicates no tillage.
b
Model R2 was computed as the ratio of the sum of the main and interaction variance, relative to the total variance (residual + main effect + interaction).
