【 摘 要 】

The aim of this study was to evaluate the influence of an application ofdifferent rates of mineral fertilizers and their combination with associativeN-fixing Klebsiella planticola and Enterobacter spp., and sampling period onthe number of fungi in Cambisol and grain yield of maize. The investigationwas conducted on Mladenovac experimental station and in the Laboratory ofInstitute of Soil Science, Belgrade, during 2006. Unfertilized soil was usedas the control soil. Each of the studied variants was carried out in threereplications. The effect of the studied fertilizers was determined threetimes during the maize growing season, the number of fungi being determinedby indirect dilution method on Czapek nutritive medium. The results of thestudy showed that all fertilization variants studied influenced, more orless, fungal growth in the study soil. However, the applied high content ofmineral nitrogen, phosphorus and potassium, as well as their combination withbacterial inoculants brought about the highest increase in the number offungi during all studied vegetation periods of maize. The highest increase inthe number of soil fungi was registered in the second sampling period. Thehighest increase in the grain yield of maize was obtained by combinedapplication of microbial inoculants and high rates of mineral NPKfertilizers.
