Rape culture is efficient only if the conditions for obtaining high seed production are satisfied. Rape seed contains 40-49% unsiccative oil with iodine index between 94-112. Rape is a good honey plant, offering early pick for bees. From one hectare of rapeseed it can be harvested up to 80-90 kg of honey. Rape production is strongly influenced by the technology used. Rape culture is effective in conditions which ensure optimum technological conditions for obtaining seed production and higher oil. Rape seed oil is a key ingredient in many foods. Its reputation as a healthy oil has created high demand in markets around the world, and overall it is the third most widely consumed vegetable oil in the world. The oil has many non-food uses, and often replaces non-renewable resources in products including industrial lubricants, biofuels, candles, lipsticks, and newspaper inks. The used agrofond was N 90 P 90 K 90 , the other technology elements are specific to the area. The experimental results were calculated and interpreted by specific methods of experimental technique. For research, several varieties and hybrids belonging to different companies were used: PAMELA variety (LG), EXOTIC and EXTEND hybrids (Monsanto) and PR46W14 hybrid (Pioneer). Analysis of average production achieved by varieties and hybrids under study, points out that there are small differences between them. In the bifactorial experience from S.C.D.A. Lovrin, in average favorable climatic conditions, on four rapeseed cultivars were obtained yields of over 3000 kg / ha, and even 3460 kg / ha at Extend hybrid. At all four cultivars tested, the yields are strongly influenced by sowing density. Best results are obtained in the range of 100-150 g.s./m² sowing density. At the sowing density of 100 g.s./m², increase production of 344 kg / ha is provided statistically as very significant. In the c limatic conditions of 2011, the highest yield is achieved at EXTEND hybrid, 3460 kg/ha . In terms of seeding density the best results are obtained by sowing rape at a density of 100 g.s./m², 3508 kg/ha .
