Abstract
Different types of fertilizers, such as chemical fertilizers, organic fertilizers and natural fertilizers are available on the market. The type of fertilizer has a large impact on plant production quality. The aim of this study, which was conducted under field conditions in the village of Jurumleri near Skopje, North Macedonia, was to investigate the influence of the application of two different types of fertilizers on leaf area and stomatal density in potato. The influence of the microbiological fertilizer Slavol and the organic fertilizer Biohumus was investigated. Also, a control plot without any fertilizer was used. A statistical tool (ANOVA test) was used for data analyses. The results showed that a statistically highly significant difference in average leaf area was found between plants treated with Slavol and plants treated with Biohumus (p<0.001). Also, a statistically highly significant difference was detected in stomatal density between plants treated with Slavol and control plants (p<0.001). A very significant difference was noticed between plants treated with Slavol and plants treated with Biohumus (p<0.01). The microbiological fertilizer Slavol showed better results than Biohumus in our research.

Summary
Potato (Solanum tuberosum L.) belongs to the Solanaceae family and it is a globally important crop plant producing high yields of nutritionally valuable food in the form of tubers. Increases in dry matter (Rembialkowska, 1999; Moschella et al, 2005), vitamin C (Hajšlová et al, 2005), phenolic compounds (Hamouz et al, 2005), total amino acids (Maggio et al, 2008), total proteins (Camin et al, 2007; Maggio et al, 2008), total sugars, and mineral elements (Wszelaki et al, 2005; Hajšlová et al, 2005; Rembialkowska, 2007) were noted in organic potatoes compared with conventional potatoes. Significant differences were not detected between organic and conventional potato tubers regarding starch (Makaraviciute, 2003; Maggio et al, 2008), essential amino acids, reducing sugars and dry matter (Maggio et al, 2008), phenolic compounds (Woese et al, 1997) or ascorbic acid and dry matter (Camin et al, 2007).
