The nutritional unbalance and the low fertility of the soil is known to influence plant and seed health, turning them more susceptible to pathogens. Brown Spot caused by Septoria glycines and Leaf Blight caused by Cercospora kikuchii may cause yield losses up to 20% in the soybean crop. The objective of this study was to evaluate the severity of these foliar diseases in field conditions, as affected by 40 different soil fertilizers treatments, as well as to observe the sanity of soybean seeds (cv. BRS Sambaíba). The treatments consisted of different amounts of simple superphosphate (SSP), triple superphosphate (TSP), KCl, ZnSO4, MnSO4, CuSO4, H3BO3, Na2MoO4.2H2O, CuSO4, FeSO4 e 3MgO.4SiO2.2H2O applied on the soil (broadcast) and incorporated at 15cm, prior to soybean planting. Disease severity (percentage of infected leaf area - i.l.a.) was evaluated when plants reached the R6 development stage. Soybean productivity and seed pathology were evaluated in the laboratory. The treatments without potassium (KCl) showed higher disease severity (39.5% i.l.a.), when compared to complete check plus nitrogen (19.5% i.l.a.) and complete check (20% i.l.a.). On the other hand, plants grew on the absence potassium manure showed low productivity (2718 kg.ha-1), when compared to complete check plus nitrogen (3649 kg.ha-1) and to complete check (3618 kg.ha-1). It was observed no difference among treatments regarding to the incidence of Aspergillus flavus, Aspergillus sp., Fusarium sp., Cladosporium sp., Rhizopus sp., Penicillium sp. and bacteria. Storage fungi were observed in all treatments, while the other seed pathogens were present on some but not on all treatments.
