A field experiment on semi-early Dutch variety of potatoes Agria was carried on the experimental field of Plant growing department of Agriculture University - Plovdiv during the period 2002-2004. A standard method of 4 repetitions on plots of 50 m 2 was used to determine the influence of new granule fertilizers and Black sea sapropel on tuber yield and starch content. Increasing of 9.15-15.1% of tuber yield was determined and increasing of the starch content with 0.25-1.54 points.
