- Intervention effect Total tomato yield decreased linearly with increasing shade.
- Intervention effect Marketable yield did not significantly differ among shade treatments.
- Intervention effect The marketable fruit fraction was greatest under 50% shade.

- Intervention effect The marketable fraction under 50% shade exceeded no shade by 7% in 2004 and 2005.
- Observation Shade most strongly affected cracked skin among defects.
- Intervention effect In sensitive cultivars, cracked skin affected up to 35% without shade but 24% to 26% under 50% shade.
- Observation Shade density showed no consistent trend for green shoulder, blossom end rot and irregular shape fractions.
- Association Shade effects increased with shading duration.
- Intervention effect Total yield showed no effect of 50% shade within 20 days.
- Intervention effect Total yield decreased 30% after at least 50 days of shading in 2005.
- Intervention effect Marketable yield declined only after over 45 days of shading in cultivars insensitive to cracking or uneven ripening.
