Avaliação da produtividade e qualidade do cafeeiro irrigado por diferentes sistemas e cultivado em condições de cerrado.

Abstract

With the use of irrigation in coffee, it was possible to turn viable its cultivation in regions previously considered marginal for its implantation. The objective of this work was to evaluate different overhead irrigations for the coffee plant (center pivot in circular planting, drip irrigation, net sprinkler and "gut"), being compared with a treatment no irrigated. This work was installed in the Experimental Field of the University of Uberaba, with the cultivar Catuaí Vermelho planted in spacing of 4,0m x 0,5m. After 5 harvests, it is concluded that in the climate conditions and soil of Uberaba, the productivity of the no irrigated coffee is harmed by water stress. The irrigated areas, compared with the witness, presented yields from 75 to 137% superior. Using overhead irrigations with smaller uniformity that drip irrigation and center pivot, coffee irrigation is viable. Regarding the final quality of the drink coffee, superiority of the witness is observed without irrigation, although with final concepts were similar to the obtained by the irrigated treatments.
