This work was developed with the objective of evaluating the development of the rocket fertilized with different organic fertilizers and irrigated with water of different salinity levels. The design was used randomized entirely in a factorial scheme 5 x 4, resulting in 20 treatments with 3 repetitions, being the experimental unit acted by a plant/vase. The first factor was composed by 5 levels of salinity of the irrigation water and the second by 4 different compositions of the substrates (S1 - Soil, S2 - Soil + Manure bovine (3: 1), S3 - Soil + Manure ovino/caprino (3: 1) and S4 - Soil + earthworm Humus (3: 1)). They were appraised the number of leaves, leaf area and matter dries of the aerial part. The number of leaves, leaf area and matter dries of the aerial part were reduced with increment of the salinity of the irrigation water. The sources of organic fertilizer studied influenced significantly in the answer of the rúcula the salinity, being an alternative for the cultivation of this vegetable under saline condition. The bovine manure presented the best acting in the development of the plants.
