• Abstract:

  Spontaneous species are present within the herbaceous extract of the caatinga, arising spontaneously due to the seed bank present in the soil, and their use as fertilizer with the mixture of other sources is of great relevance. The experiment was developed at the Rafael Fernandes experimental farm, belonging to the Federal Rural University of Semiárido-UFERSA, with the aim of evaluating organic fertilization with rooster tree (Calotropis procera) in addition to cattle manure in radish production. The experimental design used was complete randomized blocks with six treatments and four replications. The treatments consisted of evaluating the mixture of six quantities of rooster tree (Calotropis procera) plus cattle manure (0; 5.0; 10.0; 15.0; 20.0 and 25.0 t ha-1 on a dry basis). The radish was planted thirty days after incorporation, and the Crimson Gigante variety was cultivated. The characteristics evaluated were: plant height, number of leaves, root diameter, root plus part area, number of radish bunches and dry mass of roots. The greatest agronomic efficiency of radish was observed in the amount of 18.46 t ha-1, with a maximum value of 778 g m-2, equivalent to 15.55 units of sauces m-2. The mixture of alternative fertilizer sources is of utmost importance for the supply of soil nutrients. Rooster tree (Calotropis procera), as well as cattle manure, are sources of fertilizers found within the vegetable production areas in the study region.
