Introduction Oats is one of the most important cereal, being known since the fourth century B.C., as an exceptional energizing for the cold and wet season (Mogârzan Aglăiţa, 2004). Oats production has continuously decreased, whereas the demand for oats as a human food has increased because of its dietary benefi ts of the whole grain and β-glucan content (Buerstmayr et al., 2007). Currently, it is widely used as a fl akes, which are more digestible and tastier than those of barley, being recommended especially for: hypothyroidism, sterility and impotence adjunct, sensitivity to cold, sand gallbladder and kidneys, reduce the cholesterol, regulate the activity of heart and helps digestion (Ciuculin V. 2006). Material and methods This paper intends to realize some researches about the infl uence 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). In the spring of 2013, within the ARDS Secuieni, on a typical cambic chernozem, was established an experimental fi eld after the „subdivided parcels” method, with random variants, in three repetitions, which was bi-factorial, AxB type. Factor A is the distance between rows with three graduations (12.5 cm, 25 cm and 37.5 cm) and factor B is the sowing density with fi ve graduations for each distance between rows. Results and discussions Due to the researches, it has been found the highest values   of all three productivity characters 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 panicle weight 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. Conclusions For a better quality seeds of oat, used for human consumption in therapeutic purposes, it is recommended that the distance between the rows to be at least 25 cm and the sowing density to be reduced, even though the yields obtained will be relatively lower.
