Investigations were carried out during 2000, 2001 and 2002 in alluvial soil in tobacco produc-ing region of Ohrid and Struga, with the new Burley variety B 2/93, created in Tobacco Institute- Prilep. Subject of our investigations was the mineral nutrition with four rates of nitrogen (variant nourished with 55 kg N/ha and variants fertilized with 100, 150 and 200 kg N/ha), a constant rate of phosphorus and potassium (P2O5- 150 kg/ha, K2O - 120 kg/ha) and irrigation by regular watering at 15-20 day intervals. The humidity of soil during investigations was maintained at 50 70% of field capacity. According to the results, with the increased rates of nitrogen, the nicotine content increased from 1.73% to 2.30%. The content of proteins varied in a close range of 8.98% - 9.74% and soluble sugars were present in very low rates of 0,76 - 1.32%, typical for this tobacco. The increased rates of nitrogen did not have a great influence on the content of mineral matters, and their percentage in all investigated variants ranged about 20%.
