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-Goi&aacute;s. 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. Catuca&iacute; Amarelo 2SL presented higher growth than the other evaluated genotypes. The genotypes Catigu&aacute; MG 1, Acau&atilde; Novo, Acau&atilde; 2 and 8, Catuca&iacute; Amarelo 24/137, Catuca&iacute; Amarelo 2SL, Asa Branca, Para&iacute;so H419-10-6-2-10-1, Catua&iacute; Vermelho IAC 15, Acau&atilde;, Sarchimor MG 8840, IPR 98, Araponga MG 1 and Obat&atilde; Vermelho IAC 1669-20 were the ones that had the highest productivity.

Highlights

The coffee tree originates in Africa, from regions where there is an extensive period of drought
The correlation between productivity and the ten phenological characteristics evaluated at 36 months after planting was significant, except for number of nodes in the plagiotropic branch 2 (Table 3)
The genotypes Catiguá MG 1, Catuaí Vermelho IAC 15, Catucaí Amarelo 24/137, Acauã 2 and 8, Paraíso H 41910-6-2-10-1 presented smaller diameter of the orthotropic branch in the two evaluated periods, but are among the which belong to the group with the highest average productivity

Summary

Introduction

The coffee tree originates in Africa, from regions where there is an extensive period of drought. This fact led several species of this plant genus to develop an adaptation to different edaphoclimatic conditions (Aerts et al, 2017; Herrera & Lambot, 2017). The custom of drinking coffee was given by the Arabs (Aerts et al, 2017). It is considered the most consumed beverage in the world, Brazil being the second largest consumer, losing only to the United States (CECAFÉ, 2018). Its importance in the world agricultural scenario is due to the economic bias, and to political and socio-cultural aspects (Aerts et al, 2017)
