ANDY ANDREWS Lancaster Farming Staff NEW HOLLAND (Lancaster Co.) Increased carbon dioxide in a greenhouse may result in a bet ter tomato crop yield, said Mike Orzolek, Penn State extension vegetable specialist, on Monday at the New Holland Vegetable Day at Summit Valley Elementary School. “Increased lighting does not yield a better tomato harvest in greenhouses,” said Orzolek to about 75 vegetable farmers from around the Susquahanna Valley. Farmers often fail to consider proper greenhouse ventilation. “Ventilation is also critical, and fans with two speeds work best," said Orzolek. “Some will try to sell you the Dutch house passive ventilation type of system,” he said. “But passive ventilation does not work in Pennsylvania. It works only if they put in fans with active ventilation.” A nutrient injection system is also a large part of the greenhouse process. Orzolek examined the various stages toward growing good plants, through the tradition al methods and with hydroponics. Proper feeding, pruning, and trans planting will help ensure a good crop harvest Orzolek was one of nine speak ers invited by the Penn State Col lege of Agriculture cooperative extension to the New Holland Vegetable Day.
