There are thousands of acres of guar (Cyamopsis tetragonoloba) throughout the semiarid areas of Texas and Oklahoma. Guar can be characterized as an extremely drought tolerant summer annual legume that is adapted to the poor sandy soils found throughout the region. Guar produces a bean about ½ the size of a soybean. The endosperm of the bean contains galactomannan gum, an industrial gum used in paper sizing, petrochemical applications, and cosmetics. In addition, guar gum can be used as a thickening agent in ice cream and instant puddings. Guar meal is also an excellent source of protein which can be extruded into feed pellets for animals. Currently, most of the domestic guar beans are imported from either Pakistan or India; therefore, development and promotion of guar production would be beneficial to agriculture in this area.
