20.500.12556/DKUM-66920 Primerjava števila in skupne mase deževnikov v različnih pridelovalnih sistemih po spravilu soje in ajde Comparison of number and weight of earthworms in different cropping systems after soybean and buckwheat harvesting Deževniki so pomemben del živega sveta v tleh in so indikatorji rodovitnosti tal. Na njihovo število in maso ima vpliv način kmetijske pridelave, kar smo preučevali na trajnostnem poskusu, ki poteka na Fakulteti za kmetijstvo in biosistemske vede od leta 2007. Pri štirih pridelovalnih sistemih (ekološkem, biodinamičnem, konvencionalnem, integriranem) in kontrolnem obravnavanju smo oktobra 2015 po spravilu soje in ajde analizirali število in maso deževnikov. Število malih, srednje velikih in velikih deževnikov, skupno število in skupna masa so po spravilu soje v povprečju 100-krat večji v primerjavi z ajdo. Na površini 0,25 m2 je bila največja skupna masa deževnikov pri soji v ekološkem (24,4 g/ 0,25 m2), pri ajdi pa v biodinamičnem pridelovalnem sistemu (14,2 g/ 0,25 m2). Skupno število deževnikov je bilo pri soji (26,0), kot tudi pri ajdi (17,9) največje v ekološkem pridelovalnem sistemu. Najmanjša skupna masa je bila pri soji v integriranem (6,9 g/ 0,25 m2), pri ajdi pa v integriranem, konvencionalnem pridelovalnem sistemu in kontrolnem obravnavanju (1,8 g/ 0,25 m2). Najmanjše skupno število je bilo pri soji v kontrolnem obravnavanju (13,1), pri ajdi pa v konvencionalnem pridelovalnem sistemu (3,8). Skupno število in skupno maso smo preračunali tudi v kg/ha in št. deževnikov/ha. Rezultati so potrdili hipoteze o vplivu pridelovalnih sistemov in različnih poljščin na število in maso deževnikov v tleh. Earthworms are an important part of soil edaphone and are useful indicators of fertility of the soil. Their number and weight are affected by the cropping system, which we studied in a long-term experiment, performed at the Faculty of Agriculture and Life Science since 2007. In October 2015 after the harvest of soy and buckwheat, we analysed the number and weight of earthworms in four cropping systems (biodynamic, organic, integrated and conventional) and a control field. The number of small, medium, and large earthworms, their total number and total weight after the harvest of soy were on average 100 times larger than in buckwheat. The largest total weight of earthworms per 0.25 m2 in soy was measured in OP (24.4 g/ 0.25 m2); in buckwheat, in biodynamic (14.2 g/ 0.25 m2). The largest total number of earthworms on the same surface area in soy was measured in organic (26.0); in buckwheat, also in organic (17.9). The lowest total weight in soy was measured in integrated (6.9 g / 0.25 m2); in buckwheat, in integrated, conventional and control field (1.8 g/ 0.25 m2). The lowest total number in soy was measured in control field (13.1); in buckwheat, in conventional (3.8). Additionally, we calculated the total number and the total weight by hectare (kg/ha and no. of earthworms/ha). The results confirmed the hypotheses on the influence of cropping systems and field crops on the number and weight of earthworms in the soil. deževniki masa število ajda soja pridelovalni sistem earthworms weight number buckwheat soy production systems true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-07-17 19:01:42 2017-07-25 12:57:42 2022-08-01 13:21:08 2019-07-11 16:03:36 2017 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:YG2K2EDM VS_Jelenko_Lucija_2017.pdf VS_Jelenko_Lucija_2017.pdf 1 2F9A55C90210FB739A879B08D917C530 0d716d55598ffb46e379798232310a97d231f299e88980eb9fdcd938b676f1ce 700f3aa8-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/2f187c7f-5a6e-441f-b19b-0e96c31c3e0b https://dk.um.si/Dokument.php?lang=slv&id=114415 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
