Determinant Factors of the Adoption of Improved Maize Seeds in Southern Mexico: A Survival Analysis Approach

Maize is the most important and strategic crop in Mexico, however, this sector suffers from low productivity. Among the various strategies to improve yield by hectare, improved maize seeds play an important role. In this context, adoption studies in Mexico of these types of seeds are scarce and in general do not jointly account for the timing of adoption factors affecting the adoption decision. This study analysed the determinants of the adoption rates of improved seeds using the survival analysis method. Farm-level data were collected in 2015 through a questionnaire administered to 200 maize farmers in Chiapas, Mexico. Our results showed that 60% of the farmers who adopted the improved seeds reached the decision within a 10 years' period. Specifically, young farmers with a low number of family members from several generations of agricultural work, who exhibited positive attitudes towards innovation and with low risk perception were likely to adopt the new varieties. Furthermore, results showed that the NAFTA Mexican reform of agricultural policy in 1994 negatively affected the adoption rate of improved seeds. Improving the maize yield requires adequate extension information systems that allow farmers to receive more information on the importance of adoption innovation as well as help them market their products.
