Cucurbits

Cucurbits are members of the Cucurbitaceae family. Although there are 825 species of cucurbits, there are only four major crops: cucumber, melon (e.g., cantaloupe), squash (including pumpkin), and watermelon. All four of these are grown commercially in North Carolina with the largest production in cucumbers and watermelons and significant acreage in squash and melons. Cucumbers in North Carolina are produced for two markets: processing (pickles) and slicing (fresh market). About two-thirds of the cucumber crop is grown for processing and the remainder for fresh market. Most cucumber production is in eastern North Carolina. A smaller center of production is in the mountains, south of Asheville. Watermelons and melons are grown in the Coastal Plain. Squash (including pumpkin) is grown throughout the state, but more concentrated in the Coastal Plain.
