Seeking evaluate the availability of snap bean seeds production in organic farming conditions, two experiments were carried, in Regi?o M?dio Serrana of Rio de Janeiro State, in Paty do Alferes city. The effects of two spatial designs for plants and four dates of yield on the productivity and quality of the produced seeds were evaluated. Seeds of the cultivar ?Alessa?, determinate growth, were used in both experiments, in organic farming conditions. The first experiment was carried in a green house sized 35 m (length) x 8 m (width) x 10 m (height). The second experiment was carried outside the green house, using the exact same measures. The spatial design number 1 results in a plant distribution in a square shape and the number 2 results in a plant distribution in a triangle shape, however, both spatial designs gives a population of 20 plants per m?. Harvests were made in 4 dates: 73 DAS (Days After Seedling) ? yield 1, 78 DAS ? yield 2, 83 DAS ? yield 3 e 90 DAS ? yield 4 (inside the greenhouse); 91 DAS ? yield 1, 97 DAS ? yield 2, 103 DAS ? yield 3 e 107 DAS ? yield 4 (outside the greenhouse). The experiments were made in randomized blocks, using split plots. In four blocks, the two spatial plants design constituted the plots and the four dates of yield constituted the split plots. Characteristics of productivity (number of pods per plant, number of seed per pod, harvest index, productivity) and quality (% of water, germination - %, first count - %, germination speed index and % of strong seedlings) of seeds were evaluated. In both experiments the highest values for the harvest index were found in the latest dates of yields, yields 3 and 4. Inside the green house, the productivity was influenced significantly by the different yield dates and no significant difference was found for the spatial plants designs. In both experiments the productivity was close to the national average for determinate growth cultivars, in conventional farming seed production systems. The highest values for weight of 1000 seeds were found in the latest yield, inside (337,67 g in spatial design 1 and 393,025 g in spatial design 2) and outside (297,79 g in spatial design 1 and 320,08 g in spatial design 2) the green house. In both experiments, the values found in the germinations tests were higher than the standard required by law for trade (80%).
