A literature review of on-farm research design and data evaluation methods

The purpose of this literature review is to identify the study design and data evaluation methodologies used by on-farm researchers to date and to comment (if possible) on their potential impact on study objectives. Specific project objectives are: 1. To identify relevant sources of information with some emphasis on work carried out in North America since 1975, 2. To categorize and describe on-farm study designs and data evaluation methods, and, 3. To comment (if possible) on the potential impact of selected study design and data evaluation options on study objectives.
