摘要：Genetically modified (GM) cotton varieties have changed many aspects of cotton production in the United States. The rapid adoption of GM cotton varieties in Mississippi has allowed producers to alter certain production practices because of added benefits gained from GM varieties. This study analyses some of the effects of certain changes in some of the most relevant components of cotton production on yield that stem from the adoption of GM varieties in Mississippi by comparing production functions from 1996 and 2005.
