• green manuring

The objective of this research was to analyze the effect of the no-tillage organic green onion under living and dead soil cover, with residual application of composted mulch. The experimental design was used in randomized blocks with four replicates, in split-plot arrangement with four replications. The plot corresponded to the planting system (no-village with living mulch of Arachis pintoi, living mulch of native weed, straw mulch and conventional tillage). In each plot the split-plot were represented by the residual doses of organic compost 35, 70 e 105t ha(-1) year(-1) in the city compost. The no-tillage in the straw provided superior results to the conventional tillage of the soil and to the two no-tillage systems under living mulch of A. pintoi and native weed. The residual effect of the organic manuring grew with the increase of the fertilizer dose in the no tillage straw which didn't happen in the no-tillage with living mulch.
