The experiment was conducted in the years 2007 - 2009. The aim of the study was an estimation of the effect of sowing rate ( 6, 8, 10, 12 and 14 kg ha-1) on the quantity and quality of the yield of onion cv. Rosa Lunga di Firenze. On the base of obtained results, it was proved that used in the experiment sowing rates did not differ significantly the quantity of yield of onion cv. Rosa Lunga di Firenze. However, it was noted that the highest participation of bulbs of the least diameter was obtained when the highest sowing rate was used. Sowing rate of 14 kg/ha-1 had also an influence of decrease of single bulb weight of bulbs 2- 4 cm in diameter. Moreover, it was found that yield of onion cv. Rosa Lunga di Firenze was characterised by a high content of mineral compounds.
