The soil of the Paraiba, in generality, are acid and with low levels of available match, seriously limiting the income of the plants. A research in vegetation house was lead, with the objective to evaluate doses of calcareous soil and match in the culture of ricinus. The treatments had been composites for five levels of match: 0.0; 80; 160; 240 and 360 kg ha-1 of P2O5 and four dosis of calcareous rock: 0.0; 2.5; 3.5 and 4.5 t ha-1 in experimental delineation of blocks casualized with 4 factorial project x 3 (four levels of match and three doses of calcareous soil) more two treatments you add zero of match (0.0 P2O5: 2,5 t ha-1 of calcareous soil) and calcareous soil zero (240 P2O5: 0.0 t ha-1 of calcareous soil), with three repetitions. The calcareous soil reduced the acidity of the ground and effect of the application of the match (¿ 80 kg ha-1 of P2O5) in the presence of the collagen (¿ 2.5 t ha-1 of CaCO3) with of the calcareous soil (¿ 2.5 t ha-1 of CaCO3) in the presence of the match was not verified well (¿ 80 kg ha-1 of P2O5). The match applied in the absence of the calcareous soil was limited to the income of the culture of what the calcareous soil in the absence of the match.
