The incentive for the cultivation and consumption of non-conventional vegetables enriches the diet of people and contributes to their nutrition and food security. The aim of this study is to evaluate the organic fertilization of sorrel. The experiment was carried out from April to August 2013 in areas of the Experimental Field of Santa Rita belonging to the Agricultural Research Company of Minas Gerais (EPAMIG) in the municipality of Prudente de Morais, Midwest Region of Minas Gerais. The experimental design was in randomized blocks in a split-plot design with four replications. In the plots, five doses of tanned cattle manure corresponded to the application of 0; 25; 50; 75; and 100 t ha -1; in the subplots, two spacings were evaluated: 25 cm X 25 cm and 30 cm X 30 cm. The characteristics evaluated were total yield (YTOT, expressed in t/ha), commercial yield (YC, expressed in t/ha), and non-commercial yield (YNC, g/plant) on a fresh matter basis. The collected data were subjected to an analysis of variance, and means were compared by the SISVAR package (5%). For doses of organic manure, plants show a positive linear correlation for total number of leaves, number of commercial leaves, % of commercial leaves, total number of leaves, and commercial leaves. The maximum point of the curve was not reached. The mean numbers of total number of leaves, number of commercial leaves, % of commercial leaves, total number of leaves, and commercial leaves were higher at the smallest distances between the plants. The export of nutrients observed was K, N, Ca, Mg, P, and S. Different doses of manure and the spacing influence the productivity and the amount of nutrients exposed by the common sorrel.
