摘要：
The aim of this work was to evaluate the dynamic of the flowering and the Lotus subbiflorus Lag. Cv. "El Rincon" seed production potential. The variables studied through weekly samples from 11/13/2008 to 02/04/2009 were: number of flower buds, number of inflorescences, number of flowers, number of total legumes, weight of 1000 seeds and seed production. The experimental design used randomized blocks with treatments arranged as levels of an experimental factor, defined by the dates after seeding. The experiment was conducted with two blocks and twelve experimental units per block. Lotus subbiflorus seed production, in the South Brazil, presents problems caused by continuous flowering, difficulting to harvesting. The maximum production obtained was 63.2 kg/ha in January 2009 (4372 degree days). The weight of 1000 seeds and the number of legumes were the characteristics that most related to seed production. The constant emission of flower buds contributes negatively on the other components of seed production.
