New developments in production practices and technological advances in seed genetics give cotton farmers new options toconsider in their production decisions. This study was conducted to determine allocative efficiency and cost effectiveness ofgrowing conventional and transgenic cotton varieties under alternative cultural practices in South Georgia. Conventional,Roundup Ready (glyphosate resistant), Bt (Bacillus thurengiensis), Roundup Ready/Bt, and Buctril Resistant (bromoxynilresistant) cotton varieties were compared for conventional tillage and strip-till cultural practices. Data for the study wasobtained from a survey of cotton producers in South Georgia conducted in the early spring of 2000. A linear programmingmodel, specifically data envelopment analysis (DEA), was used to compare costs and returns associated with variouscombinations of tillage and technology. In this model, the linear program views input/output combinations of individualfields as separate data management units (dmu’s).
