Abstract:V diplomskem delu smo primerjali kako različni pridelovalni sistemi (biološko dinamični, ekološki, integrirani in konvencionalni) ter kontrolno obravnavanje vplivajo na populacijo deževnikov v tleh po spravilu oljnih buč in soje. Meritve smo opravili v mesecu oktobru 2014 na posestvu Univerzitetnega kmetijskega centra Univerze v Mariboru, na Fakulteti za kmetijstvo in biosistemske vede. Za vzorčenja deževnikov smo uporabili gorčično ekstrakcijo, sestavljeno iz 1/3 zmlete bele gorjušice in 2/3 vode in tehniko ročnega zbiranja. Parametri meritve so bili število, velikost in skupna masa deževnikov v tleh. Glede na pridelovalni sistem je bilo največje skupno število deževnikov na 0,25 m2 v biološko dinamičnem (16,1) in ekološkem (15,5) pridelovalnem sistemu v primerjavi s kontrolnim obravnavanjem (6,3). Skupna masa deževnikov v g na 0,25 m2 je bila največja v ekološkem (18,9) in biološko dinamičnem (18,3) pridelovalnem sistemu. Skupno število deževnikov glede na pridelovalni sistem, preračunano na ha, je bilo največje v biološko dinamičnem (642.600), po spravilu oljnih buč prav tako v biološko dinamičnem (561.200) in po spravilu soje v ekološkem (820.000) pridelovalnem sistemu. Skupna masa preračuna v kg na ha, je bila glede na pridelovalni sistem največja v ekološkem (757), po spravilu oljnih buč v biološko dinamičnem (590) in po spravilu soje (995) v ekološkem pridelovalnem sistemu.

Title:COMPARISON OF EARTHWORM POPULATIONS IN DIFFERENT PRODUCTION SYSTEMS
Abstract:The objective of this thesis was to compare how different production systems (biodynamic, organic, integrated and conventional) and a control treatment affect the earthworm population in the soil after harvesting of oil pumpkins and soy. The measurements were carried out in October 2014 at the property of the Center for Agriculture Sciences of the Faculty of Agriculture and Life Sciences at the University of Maribor. Mustard extraction consisting of 1/3 ground white mustard, 2/3 water and manual assembly technique, were used for the earthworm sampling. Measured parameters were number, size and total weight of earthworms in the soil. Regarding the production system the maximum total number of earthworms on 0.25 m2 was determined in biodynamic (16.1) and in organic (15.5) production system in comparison with control treatment (6.3). The average total weight of earthworms in grams per 0.25 m2 was significantly higher in organic (18.9) and biodynamic (18.3) production system. Depending on the production system the maximum average total number of earthworms, calculated per hectare was determined in biodynamic (642.600), after harvesting oil pumpkins in biodynamic (561.200) and after harvesting soy in organic (820.000) production system. Regarding the production system the highest average weight of earthworms, calculated per kilogram on hectare was determined in the organic production system (757), after harvesting oil pumpkins in biodynamic (590) and after harvesting soy (995) in organic production system.
