20.500.12556/DKUM-95264 Vpliv globine obdelave tal na zasnovo in začetno rast travno deteljne mešanice diplomsko delo Influence of soil tillage depth on the establishment and initial growth of a grass clover mixture V raziskavi je bil preučen vpliv dveh načinov minimalne obdelave tal – plitve z uporabo krožne brane in globoke z uporabo podrahljača (riperja) – na uspešnost zasnove in produktivnost travno-deteljne mešanice (TDM). Cilj raziskave je bil določiti globino obdelave tal, pri kateri so bili doseženi ugodnejši pogoji za vznik, rast in pridelek TDM ter spremljati stopnjo zapleveljenosti posevka. Poskus je bil izveden na kmetiji Ploj v Slovenskih goricah med avgustom 2024 in aprilom 2025. Na površini enega hektarja sta bili izvedeni dve obravnavanji obdelave tal, vzorčenje pa je bilo opravljeno v osmih ponovitvah. Spremljani so bili vznik in sklop rastlin, zapleveljenost ter pridelek sveže in suhe mase ob prvi košnji. Rezultati so pokazali, da globina obdelave tal ni imela statistično značilnega vpliva na vznik in začetno rast TDM, čeprav je bil pri globlji obdelavi zaznan trend večjega števila rastlin. Pri globoki obdelavi je bila zabeležena statistično značilno večja zapleveljenost (115,3 rastlin/m²) kot pri plitvi (66,7 rastlin/m²). Pridelek sveže mase in suhe snovi je bil višji pri globoki obdelavi (17,7 t/ha in 3,18 t/ha) kot pri plitvi (13,8 t/ha in 2,94 t/ha), vendar razlike niso bile statistično značilne. Ugotovljeno je, da globoka minimalna obdelava tal lahko prispeva k večjemu pridelku TDM, vendar hkrati povzroča večjo zapleveljenost. In this study, the effects of two methods of minimum tillage - shallow tillage with a disc harrow and deep tillage with a ripper — on the establishment success and productivity of a grass-clover mixture (GCM) were investigated. The aim of the study was to determine the tillage depth at which more favourable conditions for GCM emergence, growth and yield are achieved, while monitoring the level of weed infestation. The trial was conducted between August 2024 and April 2025 on the Ploj farm in the Slovenske gorice region. A one-hectare field was divided into two tillage variants and sampling was carried out in eight replicates. Plant emergence and density, weed infestation and the yield of fresh and dry matter at the first cut were assessed. The results showed that tillage depth had no statistically significant effect on emergence and early growth of GCM, although there was a trend towards higher plant density with deep tillage. Weed infestation was significantly higher with deep tillage (115.3 plants/m²) than with shallow tillage (66.7 plants/m2). Fresh matter and dry matter yields were numerically higher with deep tillage (17.7 tonnes/ha and 3.18 tonnes/ha respectively) than with shallow tillage (13.8 tonnes/ha and 2.94 tonnes/ha), but the differences were not statistically significant. It was concluded that deep minimum tillage can contribute to higher yields of GCM, but at the same time promotes higher weed infestation. obdelava tal travno deteljna mešanica vznik prirast tillage grass-clover mixture emergence growth increment true true false A.
