The Rogue Valley growers were pioneers in pear production, growing over 24 varieties and setting quality standards in packing pears. The Rogue Valley was the first and largest red pear growing region in the Pacific Northwest in the 1970s. The valley also set the standard for the quality of Bosc and Comice pears, which have become the two main varieties grown today.
Tomatoes are the most commonly produced greenhouse vegetable crop. Although greenhouse promoters claim each plant can produce 30 or more pounds of marketable fruit per year, that level of production is only possible with very high inputs in quality facilities and optimal cultural practices. In western Oregon, it's more realistic to harvest 20–25 pounds per plant space each year.
