Texas Researchers Investigating Guar for Crop Rotation

Texas A&M AgriLife scientists are involved in a project that is exploring the performance of guar as a rotation crop with wheat. The study’s long-term goal is to increase and stabilize guar production in the United States and increase the sustainability of wheat cropping systems in the Southern Great Plains region. Guar is a legume, which means its roots can associate with Rhizobium bacteria in the soil to convert atmospheric nitrogen into fertilizer for the plant and soil. It’s adapted to the semi-arid conditions of Texas and is among the most drought-tolerant crop plants, with relatively low water use. This project is focused on quantifying the performance of guar, developing improved varieties that can reduce the need for fertilizer on other crops in rotation and shorten the season, and identifying the best inoculant to use with guar.
