Southwest Purdue Agricultural Center
Size and Topography
- 220 acres in Knox County north of Vincennes; 150 tillable acres, with about 90 used for research purposes
- Sandier soils and climatic conditions suitable for melon and other horticultural and specialty crop production
SWPAC was established in 1979, when Purdue University purchased 175 acres from Hank DeBuisseret to replace a 78-acre sand horticulture farm in Gibson County. Purdue relocated the farm to Knox County to take advantage of water availability for research and to build working relationships with Vincennes University and the USDA. The university purchased an additional 45 acres from Steve Klein in 1992.

Although SWPAC is the smallest farm in Purdue’s regional farm system, it is one of the most active in research on fruits and vegetables— crops primarily grown in southwestern Indiana. Projects focus on increasing horticultural and agronomic crop yields and quality while decreasing input expenditures, including pesticides. An example of an IPM (integrated pest management) program used at SWPAC is MELCAST, a weather-based disease forecasting program developed at Purdue University to manage fungicide applications of foliar diseases of cucurbit vegetables.
Research on vegetables includes, but not limited to testing on muskmelon and watermelon varieties, new specialty crop varieties, new product testing of fungicides and insecticides for disease and insect control and organic vegetable production. Research is also conducted on growth and management of wine grapes including vinifera varities.
Research is conducted on high value protected ag crops in three high tunnels located at SWPAC.
Row crop research includes studies on weed and disease control, variety testing on corn, soybeans and canola as well as nitrogen rates.
Departments in Purdue Agriculture that currently conduct research at SWPAC include Agronomy, Botany and Plant Pathology, Entomology, Forestry and Natural Resources and Horticulture and Landscape Architecture.
