In order to ensure sustainability of maize production in short-season environments of Nigeria, the Sudan savanna taskforce of Kano–Katsina–Maradi (KKM) Pilot Learning Site promoted short-season maize varieties in 2008 via Innovation Platforms (IPs). In the light of the promoted varieties, we evaluated the adoption and net benefits (productivity and income) of the maize varieties. We used cross-sectional household data elicited from 600 sampled households, double-hurdle model and propensity score matching. There was a remarkable increase in the adoption of short-season maize varieties in 2014 compared to what was obtained in a baseline conducted in 2008. Our empirical findings revealed that the adoption of the short-season maize varieties promoted through the IPs had significant productivity and income increasing effects. This implies that policy interventions to ensure sustainable maize intensification in the face of environmental limitations, such as early and late season drought, should intensify the promotion of short-season varieties in Sudan savannas. This will require well-concerted agricultural extension that can leverage IPs in view of its potentials.

维持尼日利亚玉米生产的有利影响：采用短季玉米品种重要吗？

为了确保尼日利亚短季环境中玉米生产的可持续性，Kano-Katsina-Maradi (KKM) 试点学习站点的苏丹稀树草原特别工作组于 2008 年通过创新平台 (IP) 推广了短季玉米品种。根据推广的品种，我们评估了玉米品种的采用率和净收益（生产力和收入）。我们使用了从 600 个抽样家庭、双障碍模型和倾向得分匹配中得出的横截面家庭数据。与 2008 年进行的基线相比，2014 年短季玉米品种的采用显着增加。我们的实证研究结果表明，通过 IP 推广的短季玉米品种的采用具有显着的生产力和增收效应。这意味着，面对环境限制（例如早晚干旱），确保玉米可持续集约化的政策干预措施应加强在苏丹稀树草原上推广短季品种。这将需要协调一致的农业推广，以利用知识产权的潜力。
