Parâmetros vegetativos e produtivos de cultivares de cafeeiros após poda tipo decote

Abstract

Evaluating and understanding the different vegetative and productive behaviors of coffee cultivars after pruning are fundamental factors for the maintenance and stability of the crop, in addition to contributing to the perpetuation of the varieties in the cultivation areas and the improvement of more precise techniques to each material. In this context, the objective was to evaluate the vegetative and productive parameters of Coffea arabica coffee cultivars after neck pruning. The experiment was carried out at Universidade Federal de Uberlândia, Campus Monte Carmelo, in a randomized block design, with five blocks and eight treatments corresponding to the cultivars Acaiá Cerrado MG–1474, Mundo Novo IAC 379, Bourbon Amarelo IAC J10, Catuaí Vermelho IAC 99, Topázio MG-1190, Acauã Novo, IAC 125 RN and Paraíso MG H 419-1. In August 2019, using a chainsaw, the neckline type pruning was carried out in the eight treatments, standardizing the height of the plants at 1.5 m. The growth evaluations started in September 2019 and ended in February 2020. It is concluded that the cultivars Mundo Novo IAC 379-19 and Bourbon Amarelo IAC J10 stand out in height, crown diameter and average monthly growth rate in height. after pruning neckline. The cultivar Paraíso MG H 419-1 presents higher productivity after pruning of the neckline type, however, there is a low percentage of coarse grains. The cultivar IAC 125 RN has a higher percentage of grains retained on sieves 17, 18 and 19.
