Avaliação vegetativa de variedades de café (Coffea arábica)

Abstract

The study aimed to evaluate which of the Coffea arabica varieties analyzed were best under Areia-PB conditions. The experimental design was in randomized blocks, with 4 blocks, 6 genotypes and 10 replications per treatment. The experiment was conducted at the Chã de Jardim experimental unit, in a rural area of the municipality of Areia – PB. The Coffea arabica genotypes researched were: Arara, Bourbon, Catuaí Amarelo 62, Catuaí Vermelho 144, Catucaí 24/137 and Mundo Novo. Five variations were proven, stem diameter, crown diameter, number of branches, leaf area, plant height. For Stem Diameter, Arara presented better performance; for Diameter of Cup, Mundo Novo can be indicated; analyzing the Number of Branches, Catucaí 24/137, Catuaí Vermelho and Arara performed better; for Leaf Area, Arara stands out, followed by Bourbon and Catucaí 24/137; With regard to plant height, the highlights were Mundo Novo and Bourbon. The varieties present different performances in different morphological characteristics. The Arara variety stood out in terms of stem diameter and leaf area, while Mundo Novo was the best option for crown diameter and plant height. The number of branches, a parameter that defines productivity, macaw, catucai and red catuaí were the highlighted varieties for the Paraíba marsh.
