For guayule ( Parthenium argentatum Gray) to develop as a competitive crop in areas suitable for dryland production, information is needed on methods to establish acceptable stands. The objectives of this experiment were to evaluate the effects of planting method, application of an antitranspirant, and the addition of small volumes of water at planting on the survival of guayule transplants under dryland conditions. The study was conducted on a Uvalde silty clay loam (fine, mixed, hyperthermic Aridic Calciustoll). Planting method, antitranspirant, and moisture level at planting significantly affected transplant survival. Plant survival rates were reduced when transplants were sprayed with an antitranspirant at planting. The addition of water at planting did not significantly affect the survival of transplants with root balls. Survival rates were significantly higher for transplants without root balls that received 200 mL of water per seedling at planting compared to transplants that received no water. A transplant survival rate of 93% or greater was achieved for transplants with root balls, and for transplants without root balls when a small volume of water was applied at planting.
