| Abstract: | Zero tillage consistently resulted in reduced costs associated with equipment operations, in reduced barley yields, and in higher herbicide costs at all 4 locations. Summation of these major effects indicated that zero tillage on the average was $48.77 ha−1 (range of $18.43–68.79) less economical than conventional tillage. Long-term effects, such as erosion control, changes in soil structure and nutrients, or the indirect consequences of increased herbicide use were not considered in the economic analysis. |
