Abstract
Crambe (Crambe abssynica Hoechst) is a winter oilseed crop that has a high of oil content and it can be used as a raw matter for biodiesel production. The experiments to evaluate the effect of P fertilizers on growth and P uptake of Crambe have been conducted from July to August in 2011 and 2012 at the Western Paraná State, Brazil. The used soil was classified as dystrophic Oxisol Udic, collected in Cascavel, Paraná - Brazil. The results were submitted to ANOVA and SNK test at 5% probability. The green house experiment was arranged as completely randomized design, consisted of four treatments (control, 75 kg P205 as NP = natural phosphate, 75 kg P205 as SS = simple superphosphate, and mixture of 37.5 kg P205 - NP and 37.5 P205 of SS) and provided with six replications. The experimental results revealed that the highest chlorophyll content, plant height and phosphorus content in crambe leaves were obtained by the application P fertilizers. Application of NP increased plants height about 45% in 2011 and 66% in the 2012.
