PVGA Allocates $42,000 for Research in 2007

The Pennsylvania Vegetable Growers Association Board of Directors approved $42,000 for vegetable and small fruit research in 2007.  This puts PVGA's contributions to research over the past eighteen years at about $422,000. 

This has been made possible solely through the profits earned at the Association's food booths at the Farm Show and Ag Progress Days. PVGA will contribute up to $24,000 towards vegetable research this year and $7,993 for small fruit research.  In addition, the Association will partially fund a vegetable research technician position in the Horticulture Department at Penn State University.

The vegetable projects are funded in conjunction with the Vegetable Marketing and Research Program which will contribute about $21,000 for a total of $44,900. The projects approved for funding and their objectives are listed below.  Projects marked with an asterisk “*” were only approved for partial funding.
