To evaluate the effect of nitrogen application under fertigation on yield and production components of watermelon, a study was carried out in an experimental area of Embrapa Meio-Norte in Parnaíba, in the State of Piauí, Brazil, 02º 54' S, 41º 47' W and 46 m altitude) from September to November. The experimental design was in randomized blocks, with four replications. The treatments were composed of five doses of nitrogen (0, 40, 80, 120 e 160 kg ha-1 of N). Results showed that the quality of watermelon fruits was not significantly affected by nitrogen doses. The marketable fruit yield increased up to a nitrogen dose of 97.61 kg ha-1 of N and corresponded to 60.17 Mg ha-1.
