The effect of different levels of nitrogen on coriander yield was evaluated at the Universidade Federal da Paraíba, in Areia, Brazil, from June to August/2001. The experimental design was of randomized blocks, with five nitrogen levels (0.0; 20; 40; 60 and 80 kg ha-1 of N), and four replications. The cv. Verdão was planted in spacing of 20 cm x 5.0 cm in plots of 2.0 m². Evaluations performed 50 days after sowing indicated that plant height increased linearly in proportion to the increase in doses of N. The maximum N level (80 kg ha-1) provided an increment of 17.4% in plant height in comparison to the control. Green mass yield increased linearly, as a function of N levels, with the maximum value of 5.4 kg m-2 using 80 kg ha-1 of N, corresponding to an increment of 62% in comparison to control (3.3 kg.m-2).
