Abstract: Background: Weeds compete with crops for resources, reducing agricultural productivity. Management practices involving cover crops and potassium fertilization can influence weed community dynamics. Objective: To evaluate the weed community in a Urochloa ruziziensis-sillage maize (Zea mays L.) for silage succession system, considering different potassium fertilizer (K) rates applied to the cover crop. Methods: During the fall-winter season, treatments included U. ruziziensis with six K rates (0, 30, 60, 90, 120, or 150 kg K2 O ha−1 as KCl) and […]
