ABSTRACT

The effects of fertilization on crambe are poorly understood; in this sense, this study aimed to evaluate the crambe growth under different levels of nitrogen (0, 40, 80, 120 kg·ha^-¹), phosphorus (0, 50, 100, 150 kg·ha^-¹), and potassium (0, 30, 60, 90 kg·ha^-¹) in a greenhouse. The height of the plants, the production of dried biomass and that of 1000 grains of crambe were evaluated. The height of the plants was impaired as a function of increasing doses of nitrogen. The interaction of nitrogen and phosphorus in the crambe crop increased the number of grains and dry shoot biomass. The growth and yield of the crop were not influenced by the use of potassium in mineral fertilization.
