Abstract

The experiment was conducted in order to determine the influence of the microbiological fertilizer Slavol on the number of microorganisms in the soil where cauliflower was grown in open field. It was used the variety Barselona F1 which was grown in Skopje region during three years (2011, 2012, 2013). The treatments were as follows: Ø control - without use of microbiological fertilizer, V1 - foliar treatment every 7 days with 0.1% solution of Slavol and V-2 - drip irrigation treatment every 2 days with 0,1% solution of Slavol. The total number of bacteria and the number of examined physiological groups of microorganisms in the rhizosphere (nitrogen fixing bacteria 10-4 , cellulolytic microorganisms 10-4 , yeasts 10-4 , nitrifying microorganisms 10-4 and molds 10-3 ) were counted. According to the results during three years examination highest average number of total bacteria was determined in the variant V-1 and V-2 in comparison to control and the soil before planting. The number of nitrogen fixing bacteria was from 4863519 in V-1 to 4923807 in V-2. The number of cellulolytic microorganisms was from 3288588 in V-1 to 3312114 in V-2. The number of yeasts was lower than control (3813208) and was from 3681506 in V-1 to 2585089 in V-2. The number of nitrifying microorganisms was very high in V-1 (7502534) and V-2 (7323212) in comparison to control (1331717) and fallow land. The number of molds was higher in V-1 (422192) and V-2 (352608) in comparison to control (340149) but lower in comparison to fallow land (474851).
