| الوصف: | The supply of copper to coffee trees is of great importance, but few studies have examined the benefits of copper to plant nutrition, vegetative growth, production and rust management. The objective of this study was to evaluate the influence of a supply of copper on the development, nutrition, and productivity of coffee trees and on the incidence and severity of rust in arabica coffee trees. The experiment was carried out in the Centro de Pesquisas Cafeeiras Eloy Carlos Heringer (CEPEC) located in the municipality of Martins Soares, MG, Brazil. Treatments were arranged in a randomised block design with a split plot in time, with eight replicates. The supply of copper was evaluated in the plots, and the control trees in each subplot were used to evaluate the influence of the year on the experimental results (year 1 and year 2). In this experimental setup, the following variables were studied: the number of nodes per plagiotropic branch, the number of leaves per plagiotropic branch, the copper content in green leaf tissues, the incidence of rust and the yield of coffee beans. To evaluate rust severity and the quality of the coffee fruit (mature, immature and dry; the average percentage of fruit that float; and the quantity of beans that are retained using size 17, 16, and 14 sieves and at the bottom), a randomised complete block design was used, with four replications and eight treatments. The results indicate that Arabica coffee trees supplied with Cu accumulated more Cu in leaf tissues (increase of 81%), experienced a lower intensity of rust (decrease of 23%), were more productive and produced fruit with a larger grain size. The bienniality of coffee plant production caused different levels of vegetative growth, intensities of rust and productivity between the years evaluated. |
