Resumo:  Besides the use of fodder radish (Raphanus sativus var. oleiferus Metzg.) as green manure plant cover crops and animal feed, the seeds have high oil content and low viscosity, ideal characteristics for the production of biodiesel. Studies related to the technology of seed production for this species are insufficient to define the best spatial arrangement of plants in the field that provides higher yields associated with high-quality seeds. Thus, we investigated the space and density between plants that would be ideal for the production of high quality fodder radish seeds. We evaluated the agronomic characteristics and physical, physiological and seed health quality in recently harvested fodder radish in row spacings of 0.2, 0.4, 0.6, and 0.8 m and densities of 10, 30, 50 and 70 seeds m-2. The quality and productivity of the fodder radish's seeds were affected by the spatial arrangement of plants in the field. Seeds harvested under the spacing of 0.2 m and density of 30 seeds m-2 had better performance and physical, physiological and health quality. Alternaria sp. incidence increased with greater spacing, while Fusarium sp. incidence decreased.
