Titre anglais : Identification of the variation sources affecting coffee quality (coffea arabica) in El Paraíso and Alauca municipalities, Honduras

Abstract : Coffee quality is the result of different factors affecting the product at different stages before and after the harvest where each factor can differentiate or provide different characteristics to the drink. Among the factors affecting quality before the harvest, environmental and management factors have a significant influence. With the objective of evaluating variables related to environmental and management factors such as altitude, range, shadow, productivity, fertilization and slope exposure, in terms of physical and organoleptic coffee properties, a total of 89 samples were collected in coffee farms belonging to coffee producers associated to coffee cooperatives from the municipalities of El Paraíso and Alauca, Honduras. Three altitudinal ranges (?1060, 1061-1328 and ?1329 m) and three varieties, (Lempira (Catimor T8667), Pacas and Typica) were evaluated. These varieties were the most cultivated in both municipalities and have different genetic potential. The plots where the samples were taken from were characterized, considering their management, through surveys to farmers and slope exposure via digitized maps. The percentage of shade plus productivity was characterized using a subsample of 51 plots. The statistical analysis performed showed no interaction between the three varieties and altitude, but there were effects related to altitude and varieties on the quality. The Typica variety proved to be the one with the best quality (85,19%), followed by the Pacas (83,19%) variety. The Lempira (80,23%), variety proved to be the one with the lowest quality. Additionally, it was confirmed that the genotype was a key factor that largely determined the quality characteristics of the drink, the size and shape of the coffee beans among the different varieties of coffee examined. Considering the shade levels evaluated in this study, no effect on the drink quality was found. Shade only facilitated the formation of larger coffee beans. A negative productivity effect on the organoleptic characteristics was found.. When the analysis was performed using productivity as a co variable, the effect of the variety continued to be significant. This means that the lowest quality was not due only to the productivity by itself, but also to the variety. An effect of the topographic exposure factor was evidenced only on the size of the coffee beans. The southoriented slopes produced larger coffee beans. (Résumé d'auteur)
