| | Introduction |
 | | Since the margin for profit is much narrower for farmers in the dry brown soil zone due to lower potential yields, any advantage reducing the weed populations as a result of the opener will reduce input costs and make the option of including non-cereal crops more viable. |
| | This four-year study, located at near Aneroid, Saskatchewan, is looking at the effect of four single shoot openers (angle disc, knife, spoon, and sweep), with increasing levels of soil disturbance, on four crops (durum, field peas, barley, and desi chickpeas) in a four-year, zero-till rotation. |
| | Acknowledgement is also extended to Allan Oliver (the cooperator), and Jim Pratt, Pat Gerwing, and Trevor Lennox from Saskatchewan Agriculture and Food for their assistance on this project. |
