Methodology for On-Farm Cropping Systems Research

摘要

On-farm cropping systems research seeks to identify a technology, acceptable to farmers, that will increase production yields and/or cropping intensity while minimizing the detrimental effects of introduced changes. Described are research methods which were developed and adapted for the study of both dryland and wetland rice-based cropping systems. The manual begins by discussing general concepts; the definition of cropping systems and of cropping systems research; and the importance of on-farm research as a means of finding improved cropping systems that are acceptable to farmers.
