%X the nitrogen sources and parceling were evaluated concerning to gherkin plant, nordestino cv., in the universidade federal da para¨ªba, brazil. the experimental design was the randomized block design in the factorial scheme 2 x 7, constituted of two nitrogen sources (urea and ammonium sulfate) and seven application times: a) (100% at sowing date; b) 100% 30 days after sowing (das); c) 100% 60 das; d) 50% at sowing date and 50% at 30 das; e) 50% at sowing date and 50% at 60 das; f) 50% at 30 and 50% at 60 dap; g) 33% at sowing date, 33% at 30 33% at 60 dap, with four replicates. the average weight of the fruits was inferior, 27 and 21 g, respectively, when the ammonium sulfate was 100% supplied at sowing and 100% at 60 das, as no alteration occurring in the urea source nor between those n sources. the yield of fruits of one plant (2.364 kg plant-1), the number of fruits of one plant (64 fruits plant-1) and fruit productivity (20.93 t ha-1) were significantly higher, when the nitrogen (ammonium sulfate source) was 50% parceled at 30 and 50% at 60 das. when urea was the nitrogen source, the yield of fruits of one plant (1.437 kg plant-1), the number of fruits of one plant (48 fruits plant-1) and the fruit productivity (12.66 t ha-1) were significantly higher, when it was parceled 50% at sowing date and 50% at 30 dae.
