<b>Recovery of coffee tree (<em>Coffea Arabica</em> L.) after pruning under different irrigation depths</b> - DOI: 10.4025/actasciagron.v31i2.7039

Abstract

In order to reduce the recovery period of the orchard coffee after pruning, this work was carried out with the objective of evaluating the influence of different irrigation depths and splitting of N and K with fertirrigation on the growth of coffee plants. The experiment was carried out in southern Minas Gerais State with coffea Arabica cv. Topázio MG-1190 implanted with 1.8 x 0.7 m spacing. Irrigations corresponded to 0, 40, 80 and 120% of the evaporation from a Class A pan – precipitation (ECA-P) and N and K split in 4, 8 and 12 applications. A randomized block design with four replications was used. Plant height, diameter of orthotropic branches, number of internodes and crown diameter were evaluated. The fertilizer splitting was found not to provide any increase in growth of the coffee plant. The depth of 120%*ECA-P provided the greatest growth of coffee plants when compared to others.
