INFLUENCE OF CULTIVAR, CULTIVATION METHOD AND PLANT DENSITY ON THE PRODUCTION OF ONIONS

Daniela Dan, D. Maniutiu

Abstract


Experiments conducted in 2010 in the city Reghin, Mures County, was followed the influence of two cultivars (De Buzau and Nickerson F1), the method of cultivation and plant density on the production of onions, as well as on commercial quality of the bulbs. The method of cultivation and plant density have major influence on production. Thus, experimental version founded by the seedling culture, both density of 700 thousands plants/ha, and the 1400 thousands plants / ha, as that established by direct seeding at density of the 1400 thousands plants / ha, records production increases very significantly, compared with the variant culture established by direct seeding density of 700 thousands plants/ha. Nickerson hybrid in culture through seedling , at both densities, records production increases of 13.1% and 26.4%, compared to the control version (De Buzau, direct sowing, 700 thousand plants/ha). Variety De Buzau, at the density of 1400 thousands plants/ha, at the culture established by direct sowing, as well as the one through seedling, makes differences of production very significant positive towards the control version.
