Throckmorton Purdue Agricultural Center (TPAC)

Size and Topography

  • More than 830 managed acres five miles south of Lafayette along U.S. 231 in Tippecanoe County; 567 acres tillable
  • Rolling silt loam soils at the original farm and some variation across the Meigs addition
  • Two active manmade wetlands
  • 20 acres of timber used for forestry research


Dr. George Throckmorton donated the property to Purdue Agriculture in 1935 in memory of his father Edmund. It was deemed the “Edmund Throckmorton Farm Memorial” as a tribute to this pioneer leader of Tippecanoe County. In the late 1990's, horticultural and specialty crop research was relocated from the old Horticultural and O’Neall Memorial Farms to the Meigs Farm, which is part of TPAC. The center today encompasses four separate pieces – the home farm, Meigs North, Meigs South, and Meigs East.

TPAC is unique in its close proximity to campus. It is home to almost one-third of Purdue agricultural research projects, with current work involving 30 different crops. Research focuses on weed management, insect management, soil fertility, agronomic crop production, ornamentals, fruit and vegetable production, biological controls, systems engineering, hardwood production, woodland and habitat management, and resistance management of weeds and insects. New areas of interest include organic and high tunnel vegetable production.

Researchers from the departments of Agricultural and Biological Engineering, Agricultural Economics, Agronomy, Botany and Plant Pathology, Entomology, Forestry and Natural Resources, and Horticulture and Landscape Architecture are currently working at TPAC and the Meigs Farm.
