Oats are one of the most important cereals, known since the fourth century B.C., as an exceptional energizing for the cold and wet season (Mogârzan Aglaia, 2004). Currently, it is widely used as a flakes, which are more digestible and tastier than those of barley, being recommended especially for: hypothyroidism, sterility and impotence adjunct, sensitivity to cold, sand at gallbladder and kidneys, reduce the cholesterol, regulate the activity of heart and helps digestion (Ciuculin V. 2006). This paper intends to realize some researches about the influence of seeding density and distance between rows on the number of grains in the panicle, panicle weight and 1000 grain weight at the oat species (Avena sativa). Due to the researches, were revealed the highest values of all three productivity characters that were obtained to the variant with the sowing density of 75 g.s./m2 and the distance between the rows of 37.5 cm. The lowest average of the grain number per panicle was 25.17 and the highest was 32.57 grains. The lowest weight of panicle seeds was 0.68 g and the highest was 1.04 g. The lowest value of 1000 grain weight was 30.28 g and the highest value was 35.20 g. It was observed that the values of all three productivity elements are directly proportional with the distance between rows and inversely proportional to the number of germinable seeds sown per square meter.
