The aim of this work was to evaluate the gherkin yield in function of levels of P2O5, in Quartz Psamment. The research was carried out at Universidade Federal of Paraíba, in Areia, Brazil, from may to september/2006. The experimental design was the one randomized blocks, with five treatments (0, 60, 120, 180, 240 and 300 kg ha-1 of P2O5), and four replications. Plots contained 32 plants, spaced 2.00 x 1.00 m. The maximum number of fruits per plant (27) was obtained with the maximum level of 300 kg ha-1 of P2O5. The estimated maximum yield of fruits (14521 kg ha-1), was related with 192 kg ha-1 of P2O5. The of P2O5 level that provided larger economical income was 185 kg ha-1 yielding 14490 kg ha-1 of fruits, with an increase of fruits in the order of 11575 kg ha-1. The most economical level represented 96% of the one responsible for the maximum yield. The text of P Mehlich in the soil that had correlated with the maximum yield was 145 mg dm-3 and with the economical maximum was 142 mg dm-3 of P.
