Abstract:
Rape (Brassica napus L ssp. Oleifera D.C) is a plant of
Mediterranean origin, being largely used in the Middle Ages in the Central
and Northern European countries due to the oil obtained from seeds, used
both in cooking and in lighting. Considering these aspects, research has been
carried out at SCDCB Tg Mures to analyze the behavior of winter rape
cultivars in the presence of different doses of fertilizers based on N, P and K,
as well as by experiencing several degrees of seeding thickness. Analyzing
the profit rate according to the interactions of the researched items it
followed that in the year 2004 – 2005 the highest profit rate, of 125%; was
registered for the variant Valesca x 200 b.g./m2
x N60P0K0. In the year 2005 –
2006, the interaction between Valesca x 200 b.g./m2
x N60P0K0, had a rate of
profit of 126.6% and in the year 2006 – 2007, the variant Vectra x 200
b.g./m2
x N0P0K0 had a rate of profit of 80.1%. Among the fertilized variants,
Vectra x 300 b.g./m2
x N60P60K0 had a rate of profit of 53.20% while the
variant Valesca x 200 b.g./m2
x N60P0K0 had a rate of profit of 56%.
