Abstract
O objetivo deste trabalho foi avaliar o efeito do ano agrícola sobre os atributos fenológicos e agronômicos em diferentes cultivares de cafeeiro arábica. Os atributos fenológicos determinados foram estádios de frutificação, de gema dormente até fruto seco e duração do ciclo. Como atributos agronômicos, foram avaliados o rendimento, a produtividade, os tipos e o tamanho de grãos. O período entre antese até fase chumbinho não variou entre as cultivares para o ano agrícola 2004/2005, já para o ano agrícola seguinte a cultivar 'Icatu Precoce' apresentou antecipação da fase chumbinho, e a cultivar 'Obatã' atrasou o início do ciclo fenológico em relação às demais cultivares estudadas. A duração do ciclo variou com o ano agrícola, o que possibilitou a confirmação da influência dos efeitos ambientais nessa característica. Os atributos agronômicos (produtividade, rendimento, tipo e tamanho de grãos), independentemente das cultivares, também variaram com o ano agrícola.
The aim of this study was to evaluate cultivars of Coffea arabica on the basic of phenology and agronomic attributes a function of the year of production. The phenological attributes were evaluated regarding phenology and percentage of cherry fruits at harvesting time. Agronomic traits evaluated included productivity and outturn, type of seeds and grain size. The period between the blooms till the fruits at the beginning of growth did not vary among the coffee trees in the year of production 2004/2005. While in the following year the Icatu Precoce cultivar presented anticipation of the fruits at the beginning of growth and the 'Obatã' cultivar delayed the beginning of the phenological cycle due to the other cultivars studied. The duration of each cycle varied with the year of production and then all the coffee trees in this study could be differentiated on the timing of maturation (early, middle and late). The agronomic attributes (productivity, outturn, type and size of grains), regardless the different cultivars of coffee also varied with the year of production.
