Production Jim Motes , Extension Vegetable Specialist Warren Roberts , Extension Vegetable Specialist John Damicone , Extension Plant Pathologist Jonathan Edelson , Entomology Specialist Jim Duthie , Extension Plant Pathologist Productions Requirements Squash and pumpkin can be grown over the entire state.
Low humidity is favorable for production due to lower incidence of fruit and foliar disease.
Squash is grown in Oklahoma for both fresh and processing markets. Light sandy loam soils are best for early squash production. High labor requirements for harvesting summer squash and difficulty in controlling virus diseases can limit both squash and pumpkin production. A good summer squash yield under irrigation in Oklahoma is eight tons per acre or about 400 bushel cartons. Winter squash and pumpkin should yield 12 tons per acre or more with good management and growing conditions.
