20.500.12556/DKUM-68310 Vpliv prekrivnih rastlin na rast plevelov v posevku oljnih buč (Cucurbita pepo L. convar, citrullina (L) Greb. var. styriaca Greb.) Effect of cover crops on growth of weeds in oil pumpkins (Cucurbita pepo l. convar, citrullina (l) greb. var. styriaca greb.) Prekrivne rastline so ena izmed možnosti omejevanja rasti plevelov v posevkih. V letu 2015 smo na Pohorskem dvoru pri Mariboru izvedli poljski poskus z različnimi prezimnimi podsevi in z oljno bučo kot glavno rastlino. Namen raziskave je v integriranem pridelovalnem sistemu preučiti vplive različnih prekrivnih rastlin na rast plevelov in pridelek bučnic. V poskus so bile vključene naslednje prezimne prekrivne rastline: ječmen (J), inkarnatka (I) in grašica (G), ki smo jih v maju, pred setvijo buč, povaljali z valjarjem rastlinske odeje (Roller Crimper) in belo deteljo (BD), ki smo jo sejali 21 dni po setvi buč. Rezultate rasti in razvoja plevelov smo primerjali z obravnavanjem brez podseva in glavne rastline (KON). Z analizo rezultatov lahko potrdimo, da prekrivne rastline (PR) statistično značilno vplivajo na zmanjševanje rasti plevelov in s tem na pridelek bučnic. Podsev ozimnega ječmena (J) najučinkoviteje omejuje rast plevelov, vendar ima tudi statistično značilen vpliv na manjši pridelek bučnic. Obravnavanji I in G učinkovito zavirata rast plevelov do razvojne faze oljnih buč BBCH 700. Intenzivna rast plevelov na I in G v poznejših razvojnih fazah ima statistično značilen vpliv na nižji pridelek bučnic v primerjavi z IPL in BD, ki imata statistično značilno najvišji pridelek bučnic; (IPL 979,4 kg na ha1 in BD 925,0 kg na ha1). Sklepamo lahko, da najbolje razplevelijo posevek buč ječmen, inkarnatka in na to grašica. Cover crops are one of the possible treatment against weeds in crop production. Field trial was with different winter hard cover crops and oil pumpkin as main crop was established in 2015. The aim wasanalysed the effect of different cover crops in integrated production (IPL) system on growth of weeds on the field covered with oil pumpkin plants. Cover crops which included in the experiment were: barley (J), crimson clover (I), sweet pea (G) and white clover (BD). Cover crops were rolled (with Roller Crimper) in May, before oil pumpkin sowing, than, except white clover (BD) which was sown 21 days after pumpkin sowing. Growth and developmentof weeds were compared with experimental plot without any cover crop (KON). The results showed that cover crops (PR) have significant effect on reduction of weed growth and yield of oil pumpkins. Barley (J) as a cover crop is the most efficienty reduced crop for weeds, but at the same time shows also significant reduction of oil pumpkin yield. Plots I and G are sucessfully reduce the weeds till 700 BBCH growth stage of oil pumpkins. Intensive grow of weeds on plots I and G in later growth stages shows significant reduction of oil pumpkin yield in comparison to systems IPL and BD which results with significantly highest yield; (IPL 979,4 kg ha-1 and BD 925,0 kg ha1). We can conclude that barley, crimson clover and sweet pea as cover crops are most efficient in reduction of weeds in oil pumpkin production. prekrivne rastline pleveli valjar rastlinske odeje oljne buče cover crops weeds roller crimper oil pumpkins true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-15 23:37:52 2017-09-26 09:43:54 2022-08-01 15:24:00 2019-07-11 16:49:04 2017 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:D3RXNAAY VS_Sket_David_2017.pdf VS_Sket_David_2017.pdf 1 9302EB402194FD22DB6EC11C49641002 fcdbfe6c312c052de830dc068af3d6317e34c66fc689bbbb799fc35ca77948f1 4c030f15-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/5371a3e6-aa8b-4e99-b67a-034df87548ca https://dk.um.si/Dokument.php?lang=slv&id=118415 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
