Pruning in coffee fields is a management technique that underpins and ensures the productivity and longevity of the coffee tree. In this practice, the coffee grower removes the shoots that emerge along the main trunk of the plant, which can compete with the productive branches for water, nutrients, and energy. When left uncontrolled, these shoots weaken younger plants and, in adult crops, damage the plant structure and reduce their productive lifespan. Furthermore, they can negatively impact photosynthesis and other physiological processes essential for fruit development and production.
Even though it requires a time-consuming manual effort, agronomists and researchers recognize pruning in coffee fields for boosting crop productivity. To ensure this result, the coffee grower must perform this cleaning regularly, ideally right after the harvest. Through this prompt action, the producer prevents the shoots from turning into thick stems, which would significantly complicate future operations.
Studies show that complete and consistent pruning in coffee fields over the years can lead to significant increases in productivity. In experiments with irrigated coffee trees, total pruning showed production gains of up to 42% compared to crops where shoots were not removed. This happens because, by eliminating these unwanted shoots, the plant can direct its energy reserves to branches that actually contribute to bean production. Additionally, it facilitates other cultural practices and reduces internal competition for resources.
Moreover, this pruning practice maintains a more open and balanced plant architecture. This new structure improves light penetration and air circulation, promotes uniform flowering and fruit maturation, and makes pest and disease management much more efficient.
