| Sumario: | Tomato (Solanum lycopersicum L.= Lycopersicon esculentum Mill.) is the vegetable with the highest worldwide demand and its production is increasing un der protected agriculture, in hydroponic conditions. The excess nutrient solution (NS) applied to a substrate in hydroponics, can be drained and removed (open system) or reused (closed system) to utilize nutrients and water. However, there is a risk of root diseases by reusing NS. This study was conducted in greenhouse conditions, in order to identify the growth of root phytopathogenic microorganisms in the NS of a closed hydroponic system. The experiment consisted of four treatments: uncovered (T1), partially covered (T2), covered (T3) and encased (T4), through which the NS was con ducted from the pots to the reservoirs inside the greenhouse for reuse, with varying degrees of exposure to the elements within the greenhouse. Four replicates were made. Five samples of each treatment NS were obtained at different times and plated in a culture medium. There was no presence of pathogens that attack the tomato roots. The recirculation of the NS for growing tomatoes in the different systems used did not lead to the development of pathogenic microorganisms that attack the roots of tomato or diminish the fruits yield. Another of the benefits of these production systems is saving water and fertilizers, estimated at 25 and 30%, and reducing the polluting waste emissions to the environment. |
