    Wageningen UR Greenhouse Horticulture and Delphy conducted an experiment with sweet pepper -cultivar Maranello- on the Improvement Centre. Objectives were: Cultivate with a double screen in order to minimize radiation loss and to prevent climate shocks. Gas use for heating below 20 m³/m². The production started at the normal time after planting. The plant load was relatively high throughout the growing cycle. This resulted in a relatively low average fruit weight in the second half of the growing period. The production measured right after harvesting was 35.8 kg.m-² with an average fruit weight of 189 grams. The gas consumption amounted 16.9 m³.m-². The average daily temperature was around 20°C + 2°C / 1000².day-¹. A Luxous 1147 FR screen was 4614 hours fully deployed and a Luxous 1547 D FR screen was fully deployed for 4196 hours. The measurements of a net of radiation meter showed that because of the intensive screen use there have been almost no moments with a high net of radiation loss from the crop. Below the screens nivolators were used to realize a gentle air movement in the upper part of the crop. Hardly any infestation of fruitrot has been found. The results of this experiment fi t well with the newly developed cropping strategies in “Het Nieuwe Telen” aiming on keeping a proper plant balance and the reduction of radiation losses from the crop. This project was funded by Kas als Energiebron.
