Abstract
- The production of tomatoes in plastic greenhouses in Manitoba is economically feasible.
- Steam is generally not available for soil sterilization since gas-fired hot-air furnaces are used.
Portable steam units have been expensive to operate and not too successful. - The use of nylon re-inforced plastic films for coverings has not proved to be entirely satisfactory in our severe climate; fiberglass, although more expensive, holds greater promise.
- The yield of marketable fruit was 10–12 pounds (4.5 to 5.5 kg) per plant for the spring crop.
- Fruit produced from plants grown in a modified ‘Ring Culture’ system was equal in yield but higher in quality than those grown in standard ground beds.
- Some toxicity was experienced from the use of steam and chemicals when applied to ground beds.
- If consumers are aware of the quality differential between green-house grown and green-picked, imported field tomatoes, they are willing to pay a premium price for the greenhouse product.
