In organic and integrated production systems, application of biofertilizers and different species of microorganisms plays an important role, and its activity can influence the increase of total soil fertility, and therefore the yield and quality of safe food products. A two-year research (2011 and 2112) was conducted on the experimental field of the Institute of Field and Vegetable Crops, in the Department of organic agriculture and biodiversity in Backi Petrovac site, in order to determine whether different treatments with Azotobacter chroococcum and different concentrations of organic fertilizer Guana have influence on yield and total sugar content in the sweet corn grain. Applied concentrations of Azotobacter and foliar application of Guana did not affect the significant differences in the yield and the moisture of grain, however, significant differences were observed in the total sugar content. Increasing concentrations of Azotobacter resulted in an increase in sugar content. Also, on the average, foliar application of Guana increased the total sugar content for 1.8%.
