• At the Besor Experiment Station, Israel, two techniques for the enrichment of greenhouses with carbon dioxide were tested and compared with non-enriched growth of tomatoes. With one enrichment technique CO_2 was applied only during those parts of the day when the temperature in the closed greenhouse did not exceed 30℃ (selective enrichment). With the other technique, CO_2 was applied also during those parts of the day when the temperature would have exceeded 30℃, by intermittent cycles of enrichment (greenhouse closed) and aeration (greenhouse open). The effect of each technique on yields was tested in identical greenhouses, in which a local and a Dutch-bred variety of tomato was grown. In both varieties higher yields were obtained with intermittent enrichment compared with selective enrichment or with no enrichment.
