I work with various techniques to control weeds in dryland wheat production. This work includes seeding rates, seeding patterns, and various in-crop tillage options. Currently I am looking at the effects of green manure on moisture-limited dryland wheat production. In addition, I am studying dryland spring wheat, barley and wheat, plus fallow rotations.
