title: [First results of varietal comparison and nitrogen fertilization of rapeseed in Italy (author's transl)].
abstract: Some experiments of varietal comparison of various cultivars of rapeseed were carried out, determining the productivity, the oil yield and the analytical characteristics of the oils. Moreover the effects of nitrogen fertilization on the seed production and on oil characteristics were tested. The achieved results have pointed out that, referring to the chosen environment, the cv. "Matador" and "Leonessa" show the highest seed and oil productions, whereas oils extracted from the cv. "Sinus", "Erusine" and "Sinera" contain the minor quantities of erucic acid. It seem that nitrogen fertilization exerts no appreciable influence on rapeseed oil composition. The possibility of the utilization of cv. with law content in erucic acid confirms the practical validity of the cultivation of rapeseed as on oil plant.
