Other claims from this paper (9)
- Intervention effect Strong and moderate shading reduced the growing-period PPFD integral by 57% and 34%, respectively, relative to non-shaded crops.
- Intervention effect Model estimates put crop dry matter increment reductions at 50% and 28% under strong and moderate PPFD constraints.
- Intervention effect Measured plant dry matter increment decreased by 31% and 19% under strong and moderate PPFD constraints.
- Intervention effect Light use efficiency increased markedly under constrained radiation.
- Intervention effect Constraining PPFD had no observed effect on fruit total dry matter, sugars or lycopene concentrations.
- Intervention effect Constraining PPFD significantly increased fruit titratable acid concentration.
- Intervention effect Constraining PPFD slightly decreased fruit beta-carotene.
- Recommendation The authors conclude that systems reducing sunlight only at high irradiance have smaller yield reductions than permanent shading systems.
- Observation The authors conclude that tomato yield losses remain significant under both combined plant and energy production system types.
