Determinants of genetically modified (GM) maize adoption and the intensity of adoption in OR Tambo District Municipality, Eastern Cape Province, South Africa.

The objective of the study was to establish the factors that have significant correlation with the increase in adoption and intensity of adoption of genetically modified (GM) maize varieties. The study utilized a cross-sectional, descriptive and quantitative survey of smallholder dry maize producers. Multiple purposive sampling was utilized in the selection of 704 respondents and semi-structured interviews and pre-coded questionnaires were adopted as data collection instruments. The study sites were Mqanduli, Port St Johns and Flagstaff in King Sabatha Dalindyebo, Port St Johns and Ingquza Hill Local Municipalities in OR Tambo District Municipality. Through a Cragg's double hurdle model, the study revealed that level of education (1% level), membership to a farmer group (5% level), access to extension services and farm size (5% level) had significant positive influence on the decision to adopt GM maize. Intensity of use of GM maize was positively influenced by membership to a farmers group (5% level), access to extension services (5% level) and farm size (1% level). The study concluded that being part of a farmer organization, education, access to extension services and farm size were the most significant determinants in the dual decision to adopt GM maize and the intensity of utilization of GM maize. The study recommends awareness in line with the implemented policies and GM information dissemination toward farmer groups be promoted. The study also recommends that a balance be struck between optimization of land size devoted to GM maize and its subsequent adoption and extensive use thereof. [ABSTRACT FROM AUTHOR]
