Effects of a near infrared-reflecting greenhouse roof cover on the microclimate and production of tomato in the tropics CIGR Journal
Mutwiwa, Urbanus Ndungwa; Tantau, Hans Jurgen; Elsner, Bukhard von; Max, Johannes F. J.
The effects of a shading paint containing NIR-reflecting pigments applied to the roof of an experimental greenhouse on greenhouse microclimate, plant response of a tomato crop and fruit yield and quality were studied under the tropical climate conditions of Central Thailand. One experiment was carried out in the rainy (2006) season and in the dry (2005/2006) season.The maximal reduction of the air temperatures inside the greenhouse with the NIR reflecting roof paint was observed during the dry season. At this time the temperature in this house was 2.8 °C lower than in the control greenhouse without shading paint. On average the temperature reduction was 2 °C in the dry and 0.6 °C in the rainy season. The magnitude of the temperature reduction was...
