Desempenho agronômico de cultivares de café arábica em sistema de cultivo irrigado

Abstract

Currently, 138 Coffea arabica L. cultivars are registered at Brazil's Ministry of Agriculture, Livestock and Food Supply (MAPA). Studies focused on region competition further different farming manners may likely help in the adoption of the most proper cultivar for each specific condition. In the Cerrado Mineiro biome, irrigation is a key factor for the coffee-growing succeeds. Thus, the work goal was to assess the agronomic performance of coffee arabica cultivars at irrigated cultivation. The experiment was carried out in Patos de Minas - Minas Gerais State, at the irrigated-cultivation system, and treatments were comprised of cultivars Pau Brasil MG1, progeny H6-47-10 pl.3, MGS Aranãs, Topázio MG1190, MGS Paraíso 2, MGS Ametista, Paraíso MG H419-1, Catiguá MG2, Catuaí Vermelho IAC 144 and Sarchimor MG 8840. The agronomic performance was evaluated based on the productivity, yield, and granulometry of cultivars. Higher productivities and percentages of grains retained on the sieve mesh size 16 (or superior) were observed for the cultivars Sarchimor MG8840, Topázio MG1190, and progeny H6-47-10 pl.3. No statistical difference was verified between the cultivars' yields. Lastly, the best results for the percentage of mocha grains (values below 28%) were checked for the cultivars MGS Aranãs, Topázio MG1190, Sarchimor MG 8840, progeny H6-47-10 pl.3, Pau Brasil MG1, Paraíso MG H419-1, and Catiguá MG2.
