Produtividade de cultivares de Coffea arábica submetidas a dois métodos de irrigação no norte mineiro

Abstract

The objective of this work was to determine the variety and the irrigation method to provide the best productive performance among the five cultivars of the Arabica coffee variety: Topázio, Catuaí IAC 62, Catuaí IAC 144, Catuaí IAC 99 and Acaiá Cerrado. The experiment was carried out in an experimental area of the ICA-UFMG in Montes Claros MG. The plants had five years of implantation, with a randomized complete block design with four replicates, in a factorial scheme 5x2. The plants had a spacing of 3.5 x 0.8 m, and were submitted to two methods of irrigation, conventional spraying and drip irrigation. Data on height, crown diameter and yield were analyzed. The harvest was carried out between May and June 2013, leaving two weeks in the experimental area in natural drying, later weighed and applied the statistic with Tukey test at 0.05 probability. The Catuaí IAC 62 showed the highest productions, inferring that it is the most suitable for cultivation in the region, while Catuaí IAC 99 is less productive, showing less adaptation to climatic conditions, showing to be the least indicated among all. The drip irrigation system is the most suitable for the cultivation of the five varieties of Arabica Coffee in the North of Minas Gerais region.
