Vegetable yield is significantly influenced by the pedoclimatic conditions in the growing areas, by the applied technology and by the level of soil infection with different pathogens. We worked with 7 soil samples from Cluj County and 7 samples from Arad County. The soil samples were analyzed in terms of infection levels with various soil pathogens that cause seed rot and 'damping-off'. The presence of pathogens was determined by the 'trap plants' method. The experiment was performed in laboratory conditions, at an average temperature of 20.6-26.0°C and average relative humidity of 34.5-46.4%. In the soil samples it was determined the presence of soilborne pathogens Pythium debaryanum, Phytophthora parasitica and Rhizoctonia solani which cause seed rot and 'damping-off'. Soil samples from Cluj County presented the largest number of 'fallen' cabbage plants. Arad County showed the highest number of 'fallen' tomato plants, 38 'fallen' cucumber plants.
