20.500.12556/DKUM-54882 PREUČEVANJE KONKURENČNOSTI MED POSEVOM BELE DETELJE IN PLEVELI V EKOLOŠKI PRIDELAVI PORA RESEARCH ON EFFECTS OF WHITE CLOVER AS A COVER CROP IN ORGANIC GROWN LEEK Cilj preučevanja je bil raziskati vpliv podsevka bele detelje na pridelek pora in njegovo sposobnost kompeticije s pleveli v ekološki pridelavi. S tem namenom smo izvedli poljski poskus leta 2013 na Univerzitetnem kmetijskem centru (UKC) Pohorski dvor v Pivoli pri Mariboru. Vključenih je bilo 6 obravnavanj (por okopan (i) in neokopan (ii), združena pridelava pora s podsevkom bele detelje posejane 20.6. (iii) in 10.7. (iv) s pletjem, ter združena pridelava pora s podsevkom bele detelje posejane 20.6. (v) in 10.7. (vi) brez pletja. Raziskava je pokazala statistično značilen vpliv pridelovalnega sistema na pridelek pora, svežo maso bele detelje in svežo maso plevelov. Podsevek bele detelje je v primerih združene setve, tudi ko je bilo opravljeno pletje, negativno vplival na pridelek pora. Poznejši datum setve podsevka bele detelje zmanjša njegovo kompeticijo z porom. V primerih, ko pletje ni bilo opravljeno, so belo deteljo prerasli pleveli in je bil pridelek pora zelo majhen. V poskusu sta bila uporabljena dva kultivarja, med katerimi ni bilo statistično značilnih razlik v pridelku pora. This thesis examines the use of white clover as a living mulch in organic leek production. Its aim is to answer the question if interplanting white clover with leek can retard/decrease weed growth between leek rows. For this purpose, a field experiment was conducted in 2013 at the agricultural centre of the Faculty of Agriculture and Life Sciences (University of Maribor) in Pivola near Maribor. Six production systems were included in this experiment: leek – with (i) and without hoeing (ii), intercropping of leek and sowing of white clover on june 20. (iii) and July 10. (iv) with hoeing and intercropping of leek and white clover june 20. (v) and July 10. (vi) without hoeing. The research showed that different production systems determine the amounts of total yield for leek, fresh weight of white clover and fresh weight of weeds. In cases where intercropping and hoeing were carried out, white clover had a negative effect on leek growth. In those cases that did not include hoeing, white clover was swallowed up by weeds and resulted in an extremely poor leek growth and yield. We have, however, determined that planting white clover into leek at a later date can reduce its negative effect on leek growth and its yield. There were two cultivars used in the experiment, but their effect on the leek yield is negligible. por / podsev / bela detelja / ekološka pridelava leek / living mulch / white clower / organic farming true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2015-09-16 11:02:56 2015-10-05 10:16:34 2022-06-07 03:07:11 2021-05-13 03:17:20 2015 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:QOZKNDZH UN_Stefancic_Vita_2015.pdf UN_Stefancic_Vita_2015.pdf 1 10AEE7FB8CB9FE7891E6932B810E90A8 39fcd13eda9c77dd369223910c8878812acf538317e73bf3427a00af7aa3921c c6df4a70-7c0b-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=82198 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
