Photograph of Guar (Variety Mesa) being tested at Woodward Experiment Station. This deep rooted drought resistant legume may hold some promise as a catch crop in northwestern Oklahoma. More information is needed on harvesting and marketing the crop in this area. There is some indication it may furnish a good quality protein supplement in the feeding ration for livestock. It furnished little erosion resistance and in all probability will have to be grown in strips with erosion resistant crops. More information is needed on the residual effect due to depletion of subsoil moisture.
