Arugula is a leafy vegetable that has a short cycle, where the seedling production phase is of great importance for the arugula production chain, since this is the phase of greatest commercial development of the plant. Thus, this work aimed to evaluate the influence of different organic substrates on the production of arugula seedlings. The experimental design used was completely randomized, with four treatments consisting of substrates and five replications, totaling 20 experimental units. The treatments used were: T1: 100% soil; T2: 50% soil + 50% cattle manure; T3: 50% soil + 50% earthworm humus and T4: 50% soil + 50% chicken litter. The seedlings were cultivated in Styrofoam trays with 56 cells. Each plot was formed by eight rows with seven seedlings (56 tray-1 plants) totaling 1,120 plants. After 20 days of sowing, the percentage of emergence, emergence speed index, plant height, number of leaves, fresh and dry mass of the aerial part were evaluated. The substrate consisting of 50% soil + 50% earthworm humus showed the best performance in the production of arugula seedlings.
