Introduction: Maize is a staple crop critical to the food security and livelihoods of millions of smallholder farmers in Sub-Saharan Africa. Despite the availability of improved maize varieties, adoption rates among farmers remain suboptimal. Understanding the traits that drive adoption and identifying key production constraints is essential for the development and dissemination of varieties that meet farmers' needs. Aims: This study aimed to identifying the most valued traits of improved maize varieties from the farmers' perspective, assessing the socio-economic and biophysical factors influencing the adoption of these varieties and identifying the main production constraints faced by farmers in different agro-ecological zones. Study Design: The study was conducted in three regions representing diverse agro-ecological zones. A multi-stage sampling technique was used to select a representative sample of maize farmers. Data collection involved focus group discussions (FGDs), key informant interviews (KIIs), and household surveys. PRA tools such as pairwise ranking and matrix scoring were employed to capture qualitative and quantitative data on adoption traits and production constraints. Place and Duration of Study: The study took place at Ejura Sekyeredumasi, Nkoranza South District and Wenchi Municipal district, between June 2017 and December 2017. Methodology: Descriptive statistics were used analyzed the demographic characteristics of maize farmers as well as socioeconomic factors influencing the adoption of improved maize farming technology using SPSS 16 version. Data collected included; socio-demographic characteristics, adoption of improved maize varieties and constraints to maize production. Results: The results showed that about 78 % and 18 % of farmer respondents perceived that both fertilizers and improved seed were too expensive. Other constraints to maize production were drought, high cost of other agro-inputs, lack of improved cultivars and poor soil fertility significantly influenced the adoption of improved maize farming technologies in the area Conclusion: The study underscores the importance of incorporating farmers' preferences and addressing context-specific production constraints in maize breeding programs. Enhanced extension services, improved seed distribution systems, and tailored agronomic practices are recommended to increase adoption rates and improve productivity. Participatory approaches in agricultural research are vital for aligning breeding objectives with the real-world needs of smallholder farmers, ensuring the relevance and impact of improved maize varieties in the Ghana.
