Cropping Systems

Degrees

  • B. S., Agriculture Extension, University of Nebraska, 1960
  • M. S., Agriculture Economics, University of Nebraska, 1964

Major Project Activities

Pesticide Application Technology including drift reduction, Crop Expo's - Corn/Soybean. Herbicide resistant crops vs non herbicide resistant crops. Most profitable dryland and irrigated crop rotations, weed management in no-till and reduced-till crop production. Equipment for planting and drilling into heavy crop residues.

Extension Interests

Planning, development and implementation of crop variety testing in irrigated corn, Ecofallow corn and grain sorghum, irrigated soybeans, winter wheat, dry bean and sunflowers in WC District. Provide support to extension Program Units through inservice training, program planning, and consultation to enhance education delivery. Educational program in pesticide application. Continue development and implementation of no-till, reduced till and ecofarming crop production practices.
