Cycle pruning programmed on the grain yield of arabica coffee

Abstract

The cycle pruning programmed is a reinvigoration technique widely employed in Conilon coffee. This strategy may also be adopted for Arabica coffee to increase its crop longevity and yield. In this scenario, the present study proposes to examine the influence of the cycle pruning programmed on the vegetative and productive development of Arabica coffee. The experiment was developed in the field as a randomized-block design with four replicates. Treatments were tested in a 4 × 2 factorial arrangement consisting of four stem densities (4000, 8000, 12000 or 16000 stems ha-1) and two management strategies for the removal of plagiotropic branches (annual or biennial removal of branches which had reached 70% or more of their production capacity). For some variables, the treatments were organized as a 4 × 2 × 2 factorial arrangement in which the last factor corresponded to two regions of data collection in the plant (upper or lower). For all factorial arrangements, an additional treatment (control) was employed corresponding to traditional pruning (recepa). Annual or biennial removal of plagiotropic branches which had attained 70% or more of their production capacity can be adopted with no losses to crop yield. The cycle pruning programmed improves the distribution of branches, increases canopy area and prevents the occurrence of the “naked neck” phenomenon, observed in control treatment. Additionally, it provides better agronomic and productive performance; therefore, it can be used as a substitute for recepa.

Mechanized harvesting of conilon coffee plants using a self-propelled machine

“…Thus, the non-removal of plagiotropic branches from the lower third of the plant would bring economic advantages by reducing the cost of labor to perform the pruning, which would negatively impact harvesting efficiency. According to Baitelle et al (2019), the removal of plagiotropic branches from the lower third of the coffee tree increases its agronomic and productive performance.…”

Comparation of two pruning methods toward arabica coffee seedling growth

“…Another stimulator compounds, for instance, synthesized sucrose and nitrogen compounds within the leaves then move to cut part. At certain limit, those accumulations will stimulate new branches formation [7,8].…”

By wind or wing: pollination syndromes and alternate bearing in horticultural systems

“…Unexpectedly, some crop series appeared to display longer-term cycles (3-5 years; figure 4e,f; electronic supplementary material S7). Such a pattern could arise at farm scales as a result of pruning and subsequent recovery [64], but we would not anticipate these farmer practices to be synchronized at a national scale. Long-term climatic cycles, such as El Niño Southern Oscillation (ENSO) events, could also play a role, particularly in rainfed systems that we may expect to exhibit stronger variability than their irrigated counterparts.…”
