Soil-Plant-Atmosphere-Research (SPAR) Facility is a controlled environment research facility located on the Mississippi State University's campus. SPAR has a set of ten outdoor naturally-lit chambers, with computer control of the environmental factors. This facility was established in 1977 and has since been used for determining plant responses to a variety of environmental factors.

Currently, the research focus by the SPAR group revolves around the following areas:

• Environmental Plant Physiology - Video
• Crop Modeling - Video
• Global Change Biology
• Remote Sensing
• Bioenergy crops
