Significant differences are: coffee gross revenues: Monoculture-AF (R2=0.036, F=5.6, P=0.019), monoculture-dispersed (R2=0.06, F=3.66, P=0.014). Potential additional benefits: Monoculture- Agroforestry (R2= 0.073, F=11.5, P=9.1*10-4), Monoculture-Dispersed (R2=0.067, F=4.1, P=0.008). Coffee net revenue (R2=0.0036, F=1.1, P=0.33). Actual net revenue (R2=0.002, F=0.897, P=0.44). Potential net revenue (R2=0.003, F=0.56, P=0.43). Boxplots of revenues are included in the appendix (Figure. A6-6).
