- Abstract
The aim of this paper was to evaluate the effect of five nitrogen doses (50, 100, 150, 200 and 250 kg ha-1) on yield components and yield of watermelon cv. Crimson Sweet. The experiment was carried out under field conditions at Boa Vista, RR, on January to April 2010, under yellow oxisol. The experimental design was randomized blocks with four replications. The length of the stems and leaf number were significantly affected by treatments at, 45 days after emergence (DAE), affecting also the dry matter total in the end of cycle. The estimated maximum yield of watermelon (40.428 kg ha-1) was obtained with 144.7 kg N ha-1, while for fruit fresh mass was 9.45 kg with the application of 248,5 kg ha-1 N. The pH of the fruits were not affected by treatments, while the sugar content of the watermelon, measured in degrees Brix, was affected by the depths of nitrogen.
