This research was conducted in the Center for Practice (CEPRA) of UCEBOL, with the aim of assessing the response of the cultivation of stevia (stevia rebaudiana) a mineral fertilizer and organic nitrogen applied to soil and foliar. The treatments were: control (without fertilization), 50 kilograms of nitrogen per hectare to the soil (before seeding), 100 kilograms of nitrogen per hectare to the soil (before seeding, 3 liters of liquid nitrogen per acre to the foliage ( 3 applications per crop), 3 liters of liquid nitrogen per acre to the foliage (3 applications per crop), 500 g/m2 vermicompost (sowing) and Among the results was verified thatthe plant height is not significantly differentwhen applied fertilization treatments in any of the three courts. Butthere is a larger size in the plants before the second cut, decreasing by nearly half the third cut. Significant difference in the number of leaves in the second cut. Treatment with 100 kg N, introduced a greater number, compared to other treatments, and between them showed no statistically significant difference. The weight of the branch leaves no statistically significant differences were found between treatments.biofertilizer 400 g/m2 (for planting).ln the dry leaf yield in the second cutting treatment with 100 kg N was a significant difference compared with the witness and biofertilizer treatments, with others there was no difference.The average yield of dry leaves of all treatment was low and was approximately 300 kg / ha in the three courts. The third cut the weight of dry leaves was low, due to small size plant flowering and advanced.
