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.
