Abstract

Dry matter, resin and rubber content and yield were significantly different for whole, clipped, and bioregulator plants harvested from the agriculturally marginal soil of 95% sand after two seasons. Production functions based on water and nitrogen applications were developed to predict both the growth habit and yield potential of guayule. Although guayule has been highly suggested as a crop with a low water and nutrient requirement, moderate-to-high irrigation amounts combined with low nitrogen applications gave the highest biomass production which resulted in the highest resin and rubber yields. The bioregulator sprayings at low concentrations did not improve yields to date for the various water and nitrogen treatments.
