Crescimento, desenvolvimento e produção do crambe submetido a fertilização mineral.

Abstract

The energy crisis of recent times has become the biofuels an important of energy generation. In this perspective, the culture of crambe is an alternative for the production of biodiesel, owing to for its hardiness, earliness, high oil content and good adaptation. The appropriate management of fertilizer use in the cultivation of crambe is little known, there are no specific recommendations for fertilizing. Therefore, the aim of this research was to study the effects of mineral fertilization on nitrogen and phosphorus elements in the growth and production of crambe. The experiment was conducted in a greenhouse in a completely randomized design. The doses of nitrogen used were 30; 60; 90; 120 kg ha-1 and 50; 75; 100; 125 kg ha-1for phosphorus and potassium. The increase in production was directly proportional to increasing levels of nitrogen. The phosphorus and potassium doses did not cause significant effect on the growth of crambe.
