Abstract
Abstract Diesel exhaust was used for CO 2 enrichment of vegetable crops in inflated plastic houses. Fuel source and components of the recovery system crucially affected the elimination of other harmful gases. The absence of an activated charcoal filter and the use of fuel high in sulfur content increased ethylene, sulfur dioxide, nitrogen dioxide, and probably others. In the gas-added environment, as compared with the ambient one, lettuce grew more slowly, and leaf size and yield decreased in cucumber and eggplant. Plants were exposed to the gas-added environment for about 5 months, after which the system was discontinued. Plants did not recover, and symptoms continued despite discontinuing gas addition.
