High Tunnel Pole Bean Evaluation
There are two major types of green beans: bush or pole. Bush are short, erect plants (determinate) with a uniform pod set resulting in a short harvest season. Pole beans are trained on poles, fence, or string, and grow 7 to 8 ft in height and bear fruit continuously (indeterminate) requiring only one field planting. Further, the consumer perceives pole beans, with its longer pod, to be of superior quality. Our objective was to evaluate two pole bean varieties: Fortex, an extra long pod (11 in.) 60 day maturity, and Blue Lake, a standard pole bean variety, 6 to 7 in. round pod with 55-day maturity. Also, we wished to compare high tunnel production with field production and obtain two crops in the high tunnel by double cropping.
