Abstract: Radishes are excellent sources of nutrients, such as antioxidants that benefit the immune system, dietary fibers that aid digestion, and vitamins that help control blood pressure and cardiovascular health. Despite this nutritional composition and rapid vegetative cycle, radishes still need to be consumed more and are understudied in Brazil. Another challenge is the limited knowledge about fungi of the Trichoderma spp. genus and their combination with fertilizers. Thus, this study aimed to evaluate the growth promotion of Raphanus sativus L. under nitrogen doses combined with applying Trichoderma spp. isolates and their promoting effect on radish development. The experimental design used was a randomized complete block design in a 4 x 5 factorial scheme (isolates and doses), with seven replications, conducted in a greenhouse. The Trichoderma treatments were T1 – control without isolates application, T2 – ESALQ 1306, T3 – IBLF 006 WP, and T4 – URM 5911, and the nitrogen doses were 0, 50, 100, 150, 200, and 250 kg ha-1 of urea. The use of Trichoderma spp. demonstrates a positive effect on radish development, offering possibilities for promotion with an emphasis on lower doses of nitrogen. The ESALQ 1306 isolate (T. harzianum), at a dose of approximately 113 kg ha-1 of urea, a promotion was of 11% tuberous root diameter, 6% for the tuber root length, 50% for the leaf dry mass, 35% for the tuberous roots fresh mass, and 63% for the tuberous roots dry mass). The T. harzianum IBLF 006 WP and T. asperellum URM 5911 isolates are not recommended, as they presented an antagonistic effect.
