SUMMARY
In experiments conducted in 2010 in the Reghin vegetable basin the economic efficiency of onion culture under the cultivar influence, the culture method and plant density in culture has been pursued. The higher production costs were recorded at the seedling variations in density of 1400 million plants/ ha, which requires a lot of manual labor. Recorded profit was influenced by the purchase price which is higher for red onion than the white onion. The highest rate of profit has been realized for the red onion hybrid, grown by seedling with density of 700 thousands plants / ha.
