Desenvolvimento do Café (Coffea arabica L) sob sistema agroflorestal num latossolo amarelo distrófico em Brejo de Altitude

Abstract

In most countries, the current model of coffee production is full sun monoculture based. However, although the coffee tree is adapted to shading as it originates from the understorey of equatorial forests of Ethiopia. The objective of this work was to evaluate the vegetative development, productive performance, and adaptation of coffee cultivars in an agroforestry system in a rainforest enclave within a semiarid region conditions. 12 genotypes of Coffea arabica L. were studied. Intercropped with alleys of gliricidia. The following traits were measured: plant height, number of plagiotropic branches, and base diameter. Among small coffee trees, in the first period, only the Catiguá MG1 genotype presented a statistical difference in base diameter, and Catiguá MG3 in the fifth period. Regarding production, the Acauã genotype had the best performance in terms of harvest weight. For the tall genotype, there wa's no statistical difference in any measured trait. In the evaluation of soil quality, the SAC and SAFA subsystems presented the best results for the evaluation of the November/2021 period and for April/2022, the SAC and RTA subsystems achieved the best results.
