The experiment was carried out at the Moara Domneasca - ILFOV research station in 2011-2012 cropping year. It is a kind of bi-factorial experience, type 3x4 subjected to split plots method in four repetitions and studied the following factors: A - factor - rapeseed hybrid (a1- Exagone, a2 – Extend, a3 - DK Expower) and B - factor (b1 -N0, b2 -N60, b3 -N120, b4 -N180). In the experiment we applied a general content of P60. The most productive rapeseed hybrid in the Moara Domneasca - ILFOV was Exagone which attained an average fertilizing of 41.89 q/ha production. The Nitrogen dose which achieved the highest production was N180 with 51.28 q/ha. The Correlations show the dependence of the soil-enzymes on the applied doses of nitrogen. The total nitrogen (Nt%) and the soil pH also prove to depend on the nitrogen mineral application. The catalase activity is depending on the soil pH, it has a higher value at higher pH.
