Survival models: a tool for managing and analyzing the incidence of rust in irrigated coffee trees

Abstract

Studies related to the characteristics and health of coffee make it possible to manage and enhance the product, directly influencing its quality. Such studies are crucial for strategic marketing reasons, encompassing cost reduction, loss, and production optimization. In addition to these aspects, there are concerns about improving product quality. Thus, studying the variable time until the development of coffee rust, considering different irrigation systems, is relevant, given that this disease causes early leaf fall and branch drying, diminishing both production and product quality. In light of the above, the objective is to demonstrate that the main survival analysis models can be employed as instruments for managing and analyzing the incidence of coffee rust, considering different irrigation systems. The analysis revealed that the drip irrigation system was more effective than the others.
