CONCLUSIONS The Hybrid rapeseedseed was most productive in Moara Domneasca-ILFOV in 2011-2012 cropping year was Exagone which obtained a production average of 41.89 fertilization q/ha. At rapeseeds hybrids the average nitrogen dose which attained the highest production was N 180 with 51.28 q/ha. The maximum production in experiment was 57.45 q/ha at the hybrid DK Expower and at N 180 doses. After the first year of experimentation the nitrogen application has negatively affected the soil pH, which decreased from 5.31 to 5.04 with N 60 dose application to unfertilized. The catalase activity and the phosphatase activity were sensitive to nitrogen dose application. The Catalase activity is dependent on the soil pH, it has a higher value at higher pH. The potential breathing activity is strictly dependent on the soil cellulolytic activity. REFERENCES Barlóg P., Grzebisz W., 2004.
