Seedling production is one of the most important steps in the production of vegetables, mainly for fruit vegetables. We evaluated the production of pepper seedlings in coconut fiber substrate using fertigation. We used a completely randomized design in a factorial scheme 4x8 with four replications. The first factor was composed of four nutrient solutions applied through fertigation, and the second factor comprised eight peppers cultivars (C1: Vulcão pepper, C2: Malagueta pepper, C3: Tekila pepper, C4: Ouro pepper, C5: Doce Comprida pepper, C6: Cayenne Dedo-de-moça pepper, C7: Salar pepper and C8: Luna smell pepper). The seedlings were evaluated for the following development parameters: number of leaves, leaf area, stem diameter, main root length, height and total dry mass. All variables were affected by the ionic concentrations of nutrient solutions in all cultivars. The concentration of nutrients in fertigation solution should be determined according to the cultivar. A concentration ranging from 50 to 90% is recommended for the cultivars C1, C2, C3, C4 and C7; and from 70 to 90% for the cultivars C5, C6 and C8 for production of seedlings in floating system nutrient solution.
