Abstract

Rolling short stature crops with heavy, large diameter, gas pipes has become common in Canada. Although this technique was first utilized to push rocks into the ground to avoid combine damage and aid in harvesting lodged crops, producers in Iowa quickly learned that pushing corn root-balls flat at the time of planting can increase harvest efficiency. Typically fields are rolled shortly after planting. This study was actually two experiments—to evaluate only pre-plant rolling of corn and soybeans and to evaluate the response of emerged soybeans to rolling. The purpose of the first experiment was to determine plant and yield responses to rolling prior to planting. The second experiment evaluated plant and yield responses to rolling at four stages of soybean growth. This is the first year of a two-year study.
