Delivering genetic innovations to farmers: Challenges and opportunities for accelerated varietal turnover

The maize seed systems in Kenya are pivotal to agricultural productivity and food security, supporting millions of smallholder farmers who rely on maize as both a staple crop and a source of livelihood. While significant progress has been made in developing improved maize varieties, the adoption and dissemination of these genetic innovations remain slower than expected. This sluggish varietal turnover limits the benefits of these innovations, raising critical questions about the factors influencing seed adoption and the mechanisms needed to enhance farmers’ access to high-performing hybrids. This booklet compiles 12 research abstracts that evaluate various demand-side interventions designed to accelerate maize varietal turnover in Kenya. The studies focus on innovative approaches that empower farmers, agro-dealers, and other value chain actors with the tools and information necessary to drive adoption of improved varieties. Key topics explored include the use of trial seed packs, third party performance information for seed products, digital and social marketing strategies, agro-dealer incentives, and the integration of insurance mechanisms to reduce adoption risks. Each abstract includes the name and contact email of the principal investigator (PI) to facilitate further dialogue and collaboration. Unlike traditional studies focusing on breeding and seed production, these abstracts delve into interventions aimed at stimulating demand and addressing barriers at the farmer and market levels. By showcasing these innovative approaches, the booklet provides evidence-based insights into actionable solutions that can drive varietal turnover and enhance the performance of Kenya’s maize seed systems. For academics, policymakers, and stakeholders in the maize seed value chain, this collection offers a unique opportunity to explore and adopt strategies that align with market dynamics and farmer preferences. As we strive toward resilient and inclusive seed systems, this booklet serves as a vital resource for fostering collaboration among key actors. The ultimate goal is to ensure that smallholder farmers in Kenya have timely access to superior maize varieties, enabling them to meet the challenges of a changing climate and evolving agricultural landscape.
