In the agricultural zone of Culiacán, Sinaloa, the tomato crop is affected by Fusariumoxysporum f. sp. lycopersici race 3 (Fol3), which decreases yield and leads to high economic costs associated with controlling this plant pathogenic microorganism; in addition to the ecological impact of soil and water contamination. Thus, the objective of the present study was to evaluate four nutrient solutions to assess their effects on the incidence and severity of fusarium wilt induced by Fol3, on the nutritional status of the crop, and on the commercial yield. Hybrid tomato plants of the round Imperial® and Roma Reserva® types were planted in substrate infested with Fol3. The nutrient solutions, based on the Steiner universal solution, were spiked with two concentrations of N-NO 3-(12 and 9 moles m-3) and two concentrations of Ca 2+ (9 and 11 moles m-3), which were combined to yield four nutrient treatment conditions. Statistical analysis did not show significantly different disease incidences among the four treatments; however, the severity of the disease was significantly reduced (p<0.05) in treatments containing 12 moles m-3 of N-NO 3-and 11 moles m-3 of Ca 2+ for Imperial hybrid plants, and no significant difference was observed (p>0.05) for the Reserva hybrid plants at different Ca 2+ and NO 3-concentrations. The nutritional status of the plants was adequate in the four nutrient solutions, and the fruit yield increased 38% in nutrient solution 2 for the Imperial tomato hybrids, while solution 1 (Steiner, 1984) inoculated with Fol3 presented the best results for the Reserva tomato hybrid. common hybrid used in the zone, specialized for the export trade, which attributes and quality were accepted for the customer, and can used the result for other zones whit semi-hydroponic system. Fol incidence show the scope of the disease on the crop and was measure the real problem in the zone of Culiacan, Mexico. Limitations.
