Abstract
Balanced plant nutrition is essential for strengthening natural defenses against foliar diseases in coffee crop. This study aimed to assess soil conditioners, soil coverings, and fertilizers to enhance coffee plant nutrition and to manage brown eye spot (BES – Cercospora coffeicolla Berkeley & Cooke). The factors studied were arranged in a 3 × 2×5 factorial scheme, totaling 30 treatments, allocated in a split-split plot. The soil coverings were plastic film, Urochloa decumbens, and no-covering. The fertilizers were conventional and controlled release. The soil conditioners were organic compost, coffee husk, agricultural gypsum, water-retaining polymer, and check. The experiment was arranged in a randomized block design with three replicates. The BES incidence, soil fertility, and foliar nutrient levels were assessed. The data obtained were submitted to the analysis of variance and, when significant, the Scott-Knott test was applied at 5% probability. The results of BES incidence and foliage were plotted in progress curves, together with the mean of weather variables. The results of nutrient foliar contents were analyzed with principal component analysis (PCA). Urochloa decumbens and soil conditioners, organic compost, and coffee husk, improved soil chemical attributes, with nutritional balance of plants, reducing BES incidence and defoliation. Controlled-release fertilizer, even without significant reduction of BES, allowed improvements in foliage. The agricultural gypsum caused nutritional imbalances and possible nutrient leaching, contributing to the increase of BES.
