SANCHEZ-TOLEDANO, Blanca; CUEVAS-REYES, Venancio; PALMEROS ROJAS, Oscar  and  BORJA BRAVO, Mercedes. Modeling the adoption of a garlic (Allium sativum L.) variety in Mexico through survival analysis. Rev. Fac. Cienc. Agrar., Univ. Nac. Cuyo [online]. 2021, vol.53, n.2, pp.178-192. ISSN 1853-8665.

The objective of this research was to analyze adoption over time of the improved garlic variety CEZAC 06, in North-Central Mexico, determining factors associated with this adoption process through survival analysis (SA). The data was collected at farm level, through a questionnaire administered to 80 garlic farmers in Zacatecas, Mexico, in 2019. Among respondents, 62.5 % of the farmers adopted CEZAC 06 during the first two years after it was introduced. The factors affecting the adoption process were: farmer age, how long the farmer had been in business, number of hectares for garlic production, yield, number of college-educated family members, income from crop farming, income from garlic farming, from the federal government and belonging to any type of membership to an organization. Improving garlic bulb yield and quality requires an adequate extension program commu nication system that provides for farmers to receive updated and reliable information on the importance of technological innovation. Survival analysis can evaluate changes in explanatory factors between farmers and other changes over time, thus addressing deci sion-making and adoption processes for improved seeds.
