没有采用合适的玉米品种被认为是肯尼亚西部玉米产量低的第二个最重要的制约因素。为了更多地采用合适的品种，重要的是了解影响品种选择和采用的因素。本研究旨在确定影响玉米杂交种WH 502采用的品种、社会经济和制度因素。数据是从肯尼亚西部三个地区的504户家庭和68名仓储商中随机抽取的。结果表明，影响WH502采用的主要因素是丰产性、早熟性和非倒伏性，而重要的社会经济因素是养殖场规模、牛的所有权、农民的文化程度和地方特色。农民不喜欢的WH502的特点是耐贮性差、盖度差。研究发现，在让农民了解WH 502品种方面，邻居比公共推广服务发挥了更重要的作用。育种者需要改善WH 502的耐贮性和外壳覆盖属性，以维持或提高采用率。政策制定者应该支持向农民推广新技术的非正式方式，并通过提供成人教育来支持农民。
Non-adoption of suitable maize varieties was identified as the second most important constraint responsible for low maize yields in western Kenya. In order to increase adoption of suitable varieties it is important to know the factors that influence the choice of variety and adoption. This study aimed at identifying varietal, socio-economic and institutional factors that influence adoption of the maize hybrid, WH 502. Data were collected from a random sample of 504 households and 68 stockists from three districts of western Kenya. Results showed that the main attributes of WH 502 that influenced its adoption were high yield, early maturity and non-lodging, whereas the important socio-economic factors were farm size, cattle ownership, education level of the farmer and locality specific characteristics. The attributes of WH 502 that farmers disliked were poor storability and poor husk cover. Neighbors were found to play a more important role than the public extension service in making WH 502 variety known to farmers. Breeders need to improve on storability and husk cover attributes of WH 502 so as to sustain or improve adoption. Policy makers should support informal ways of extending new technologies to farmers and also support farmers through provision of adult education.
