Growth and Productivity of Irrigated Coffee Trees (Coffea arabica) in Ceres-Goiás

Abstract

The objective of this work was to evaluate the growth and productivity of cultivars and progenies of arabica coffee under irrigation by driping in Ceres-Goiás. It was conducted in the experimental area of the Goiano Federal Institute-Ceres Campus. A total of 35 treatments were randomized blocks with four replications, from January 2017 to August 2018. At 30 and 36 months after planting, the diameter of the orthotropic branch, canopy diameter, plant height, number of nodes in the plagiotropic branch 1, length of the plagiotropic branch 1, number of nodes in the plagiotropic branch 2, length of the plagiotropic branch 2, length of the plagiotropic branches 1 and 2, number of nodes of the plagiotropic branches 1 and 2 and productivity were evaluated in 2018. The linear simple correlations were estimated in all evaluated characteristics. There was a difference in growth and yield of the evaluated genotypes. There is a positive correlation among the vegetative characters and the productivity. Catucaí Amarelo 2SL presented higher growth than the other evaluated genotypes. The genotypes Catiguá MG 1, Acauã Novo, Acauã 2 and 8, Catucaí Amarelo 24/137, Catucaí Amarelo 2SL, Asa Branca, Paraíso H419-10-6-2-10-1, Catuaí Vermelho IAC 15, Acauã, Sarchimor MG 8840, IPR 98, Araponga MG 1 and Obatã Vermelho IAC 1669-20 were the ones that had the highest productivity.
