The aim of this study was to evaluate the effect of different soil coverings, fertilizers and soil conditioners on Brown eye spot (BES) management. The factors studied were arranged in a 3x2x5 factorial scheme, totaling 30 treatments, and allocated into a split-split plot arrangement. The experiment was arranged in a randomized block design with three replicates. The plots were composed of soil coverings, including polyethylene film, Urochloa decumbens, and an area with no cover. The subplots were treated with conventional and controlled-release fertilizers. The subdivided subplots were composed of soil conditioners, including organic compound, coffee husk, agricultural gypsum, hydroretentor polymer and check. The leaf and fruit BES incidence, foliage, soil moisture, plant growth, leaf area index, and productivity were evaluated. The data obtained were subjected to variance analysis and the Scott-Knott test (p < 0.05). U. decumbens and soil conditioners, including organic compound and coffee husk, promoted a higher soil moisture, therefore reducing the leaf and fruit BES and consequential defoliation. Despite the high soil moisture content present under the polyethylene film and subsequent promotion of vegetative growth, this soil covering provided a higher incidence and severity of BES in the fruits and leaves and defoliation. Controlled-release fertilizers, even though they did not promote a significant reduction in the incidence of BES, enabled improvements in the vegetative growth and foliage production. Agricultural gypsum, even though it promoted an improved productivity, caused nutritional imbalances and possible nutrient leaching, thus contributing to an increase in the occurrence BES, which caused a reduction of 72 to 81% in the leaf area index of coffee crop.

本研究的目的是评估不同的土壤覆盖物、肥料和土壤调理剂对棕色眼斑 (BES) 管理的影响。所研究的因子以 3x2x5 因子方案排列，总共 30 个处理，并分配到裂区排列中。实验采用随机区组设计，重复 3 次。这些地块由土壤覆盖物组成，包括聚乙烯薄膜、Urochloa decumbens、和一个没有掩体的区域。子地块用常规和控释肥料处理。细分的小区由土壤调理剂组成，包括有机化合物、咖啡壳、农业石膏、保水剂聚合物和检查。对叶片和果实 BES 发生率、叶片、土壤水分、植物生长、叶面积指数和生产力进行了评估。对所得数据进行方差分析和 Scott-Knott 检验 ( p < 0.05 )。U. decumbens土壤调节剂，包括有机化合物和咖啡壳，促进了更高的土壤水分，因此减少了叶子和果实的 BES 和随之而来的落叶。尽管聚乙烯薄膜下存在高土壤水分含量并随后促进了植物生长，但这种土壤覆盖在果实、叶子和落叶中提供了更高的 BES 发生率和严重性。控释肥料虽然不能显着降低 BES 的发生率，但能够改善营养生长和叶片生产。农业石膏虽然促进了生产力的提高，但会导致营养失衡和可能的养分浸出，从而导致 BES 发生率增加，导致咖啡作物的叶面积指数下降 72% 至 81%。
