NITROGEN FERTILIZATION EFFECT ON THE CRAMBE GROWTH AND DEVELOPMENTABSTRACT: Aiming to study the effects of the nitrogen fertilization on the Crambe growth and development an experiment was carried out on an area of the Institute Federal of Education, Science and Technology do Rio Grande do Norte-IFRN, Apodi -RN. The study was conducted in a 5x4 factorial with randomized blocks and four replications using the cultivar of Crambe submitted to four nitrogen doses (25; 50; 75 e 100 kg ha -1 ). The data was analyzed through analyses of variance using the F test. The increasing doses of nitrogen increased significantly the Crambe growth and development.
