Crescimento de cultivares de coffea arabica L. em Areia - PB

Abstract

Coffee is one of the most important agricultural crops in the world. Within the Coffea genus, the species Coffea arabica L. and Coffea canephora are the most prominent on the global stage. For a detailed understanding of the adaptation of different coffee cultivars, it is necessary to understand how edaphoclimatic conditions can influence the development of the crop in a specific region. Therefore, the study aimed to verify the growth of six Coffea arabica L. cultivars at the Canada farm located in the municipality of Areia - PB. The variables evaluated were plant height, stem diameter, canopy diameter, number of plagiotropic branches, leaf area, length of the plagiotropic branch, number of nodes on the plagiotropic branches, and diameter of the plagiotropic branch. The data were subjected to analysis of variance, with means compared using Tukey's test at a 5% probability level. Among the six evaluated cultivars, Catuaí Vermelho IAC 144 and Catucaí Amarelo 24/137 stood out significantly for exhibiting the highest average values for plant height, surpassing the other cultivars. Regarding canopy diameter, the cultivar Catuaí Vermelho IAC 144 demonstrated superior performance compared to the other treatments. Thus, in terms of vegetative development, the cultivars Catuaí Vermelho IAC 144 and Catucaí Amarelo 24/137 stand out for showing the best performance.
