The objective of that work was to evaluate the influence of different soil mulching and doses of organic compost in the culture of the rocket. The experimental design was used in randomized blocks, in splitplot arrangement with four replications. The plot corresponded to the soil mulching (no-tillage with living mulch of Arachis pintoi, living mulch of native weed, straw mulch of native weed and conventional tillage without mulching). The plots represent the doses of organic compost (10, 20 and 30 t ha-1 in the dry compost). The variables analyzed were yield, commercial fresh matter, and dry matter of the aerial part. The dose of 30 t ha-1 provided the largest yield values and commercial fresh mass for the conventional system and straw mulch. The dose 20.49 t ha-1 increased yield and commercial fresh mass for A. pintoi mulch. The dose 20.85 t ha-1 showed greater increase in yield and commercial fresh mass for the live native weed. The tillage and straw mulch presented higher yield values for all the studied doses. The dose of 23.1 t ha-1 it promoted the largest dry mass of the aerial part. The tillage and no-tillage with straw mulch it contributed with the largest dry matter of the aerial part.
