Abstract
Sustainable and organic production systems in which the application of synthetic products are partially or completely excluded are becoming increasingly popular and are opening more opportunities for usage of microbiological fertilizers. Therefore this research is aimed at determining the impact of two types of microbial fertilizers on the morphological characteristics and the yield of carrot,to test the possibility for their extensive use.Experiment was set on open field in the area of the village Jurumleri, Skopje, during 2013. As research material was used carrot (Daucus carota L.), hybrid Maestro. The variants were set according to the type of microbiological fertilizer: Ø control - not applied microbiological fertilizer, variant 1 - treatment with microbiological fertilizer Micro - I Vita containing several groups of azotobacter, nitrifying microorganisms and phosphor-soluble microorganisms; variant 2 - treatment with microbiological fertilizer Micro - Vita II containing azotobacter, nitrifying microorganisms, phosphor-soluble microorganisms and iron.From the morphological characteristics were measured the weight of whole plant,which ranged from 73,17 g in the control to 84,00 gin variant 1,root weight,which ranged from 63,83 g in the control to 74,67 g in variant 1, lengthwhich ranged from 17,69 cm in the control to 18,28 cmin variant 1, widthwhich ranged from 2,22 cm in the control to 2,39 cm in variant 1 and index of the rootwhich ranged from 7,65 in variant 1to 7,99 gin the control. According to the results statistically significant differenceswere determined between the variants in weight of whole plant and rootweight. The highest yield was obtained in variant 1from 53,77 t/ha, in variant 2 the yield was 46,32 t/ha, while the lowest yield was obtained in the control from 45,96 t/ha. Also statistically significant difference was determined in the yield between the variants.
