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.

南非东开普省OR Tambo区市的转基因（GM）玉米收养的决定因素和收养强度。

该研究的目的是建立与转基因（GM）玉米品种的采用和采用强度增加有显着相关的因素。该研究利用横断面，描述性和定量的小农干玉米生产者调查。在704位受访者的选择中采用了多目标抽样，采用了半结构化访谈和预先编码的问卷作为数据收集工具。研究地点是俄勒冈州坦博区市的萨巴达·达林德博国王沙特阿拉伯的姆坎杜利，圣约翰斯港和弗拉格斯塔夫，圣约翰斯港和因古萨山。通过Cragg的双关卡模型，该研究表明，受教育程度（1％），加入农民团体（5％），获得推广服务和农场规模（5％水平）对采用转基因玉米的决定具有重大的积极影响。转基因玉米的使用强度受到以下因素的积极影响：加入一个农民团体（5％），获得推广服务（5％）和农场规模（1％）。该研究得出的结论是，作为农民组织的一部分，教育，获得推广服务的机会和农场规模是采用转基因玉米的双重决定和转基因玉米利用强度的最重要决定因素。该研究建议根据已实施的政策提高认识，并促进向农民群体传播转基因信息。该研究还建议在优化用于转基因玉米的土地面积与随后采用和广泛使用之间取得平衡。
