The paper presents the results obtained after performing studies in the north-west part of the country, at two varieties of onion one with yellow colour bulbs and other with red colour bulb, direct seeded in two epochs, in early spring and in late autumn at two densities of 2 cm and 4 cm between plants and 25 cm between rows. We note that the plants obtained by direct sowing in autumn epoch have completely vernalization both varieties, and both seeding densities by issuing floriferous stems, culture being compromised in terms of production of bulbs. Plants obtained by direct sowing in spring epoch in both varieties and seeding densities were normally developed, yielding an average of (58.72 t / ha) for Density 4 varietyÂ  to a density of 1 million pl / ha, andÂ  (58.19 t / ha) at a density of 2 million plants / ha. Ramata rossa di Milano variety has got an average of (53.09 t / ha) at a density of 1 million plants / ha and (58.49 t / ha) at a density of 2 million plants / ha. The average bulbs weight is 86.0 g/bulb for Density 4 variety at a density of 1 million plants / ha, 71.72 g at a density of 2 million plants / ha and 54.27 g at redÂ  variety Ramata di Milano in a density of 1 million plants / ha, 41.95 g at a density of 2 million plants / ha. Average production for the variety Density 4 to a density of 1 million plants / ha is higher than the average production at a density of 2 million plants / ha. RamataÂ  rossa di Milano variety, at a density of 2 million plants / ha, the average yield is higher than average production at a density of 1 million plants / ha .
