Estimating adoption of GMO soybeans and maize: a case study of Ohio, USA.

Abstract

This chapter takes a specific look at Ohio's adoption of genetically modified (GM) soyabeans and maize. A survey of Ohio farmers (n=130) regarding use of GM crops was conducted in May 2000. Data on attitudes and beliefs concerning GM crop adoption were collected, and GM crop acreage in Ohio was estimated. Factors affecting Ohio farmers' adoption of GM seed varieties were also investigated. Preliminary estimations have shown that there are consistent factors affecting adoption across years for the same crop as well as across crops during the same year. It has also been found that while the adoption of GM soyabeans and herbicide-resistant maize has continued to increase, the adoption of Bt maize decreased in 2000.
