Area of Focus

Western Nebraska Dryland Cropping Systems

Research Interests

  • Weed control 
  • Herbicide application technology 
  • Crop selection and rotations 
  • Crop production with limited rainfall

  • Crop residue management 
  • Crop and soil fertility 
  • Crop water use 
  • Variety testing

Major Project Activities

I am conducting studies on herbicide application technologies that can be used to improve herbicide applications. I have shown that application parameters, namely nozzles, carrier volume, and droplet size, can impact the efficacy of herbicide applications. In addition, studies demonstrated that effective use of adjuvants on specific plant species can increase herbicide efficacy. In addition to my specific area of focus, I assist other students with their research that include herbicide drift and resistance, plant diseases, and corn water use. I also assist with industry contract work that includes regulated trials, herbicide evaluation trials, hybrid and variety evaluation under dryland and irrigated conditions, plant nutrition, fungicide evaluations, seed treatments, and planting dates. I also help maintain a long-term dryland and irrigated crop rotation and cover crop studies.

Extension Interests

Provide current cultural recommendations, product evaluations and other ITM information, as appropriate via In-service Education, Master Gardener and Professional Turf Manager Training.
