Positive Selection (PS) technique has been shown to reduce virus infection and increase yields, however there is insufficient empirical evidence on how this technology affects seed yam farm productivity. This study employed Propensity Score Matching (PSM) technique to evaluate the impact of PS on seed yam yields of 368 farmers randomly selected from Ghana and Nigeria. The findings showed that educational attainment, distance from the farm to the nearest market, cropping patterns, and other factors influenced farmers' adoption of PS. Furthermore, the adoption of PS technology resulted in a 16.98 % boost in farm productivity for PS seed yam farmers compared to their productivity without the technology. It is of the utmost importance that PS adoption be supported by developing tailored training materials for farmers to improve their use of the PS technology.
正向选择（PS）技术已被证明可以减少病毒感染并提高产量，然而，关于这项技术如何影响种薯农场生产力，实证证据不足。本研究采用倾向得分匹配（PSM）技术，评估了PS对从加纳和尼日利亚随机选取的368名农民的种薯产量的影响。研究结果表明，受教育程度、农场到最近市场的距离、种植模式以及其他因素影响了农民对PS的采用。此外，与未采用该技术的情况相比，采用PS技术使PS种薯农民的农场生产力提高了16.98%。至关重要的是，应通过为农民开发量身定制的培训材料来支持PS的采用，以提高他们对PS技术的使用。
