摘要

The search for renewable sources of energy gains new options of raw materials every day, such as crops from agriculture. Oil crops, such as soybeans, canola, jatropha and crambe stand out in the west of Paraná state, Brazil. The crambe (Crambe abyssinica H.) is a promising plant in the production of oil in Brazil and is an alternative to the crop rotation system. Several studies have been conducted on crambe as there is currently little information regarding this crop in the west of Paraná. Also, studies on plant density are also required, as this factor is important to avoid competition for soil nutrients and reduced grain yield. This study aimed to assess crambe growth and production under different sowing densities. The experiment was conducted on an experimental farm in the city of Cascavel – PR. The spatial arrangement proposed in this study varied according with sowing densities of 8, 12, 17.5 and 24 kg ha-1 crambe seeds with spacing of 0.45 m between rows and 5 replications in an experimental design with randomized blocks. Data obtained were subjected to analysis of variance (ANOVA) and to regression test in ASSISTAT software. Results showed that plant height, fresh mass, dry mass, plants per linear meter and grain yield were influenced by variations in plant sowing density. Plant height (110.08 cm) and yield (2118.57 kg ha-1) showed the best results with sowing density of 8 kg ha-1. Fresh mass (67.95 t ha-1), dry mass (22.52 t ha-1) and plants per linear meter (55.60 units) reached the best results with a sowing density of 24 kg ha-1.
