20.500.12556/DKUM-12258 STIMULATORJI RASTI V EKOLOŠKI PRIDELAVI KOLERABICE GROWTH STIMULATORS IN ORGANIC PRODUCTION OF KOHLRABI V letih 2006 in 2007 je bil na kolerabici v rastlinjaku in na poskusnem polju Fakultete za kmetijstvo Univerze v Mariboru preizkušen vpliv različnih stimulatorjev rasti (Agrovit, Coralit, HB 101, Vita). Pri vzgoji sadik so bili uporabljeni posamezni stimulatorji rasti in njihove kombinacije. S stimulatorjem rasti HB 101 je bilo pred setvijo tretirano seme, Agrovit je bil primešan substratu, Coralit je bil na rastline nanesen foliarno. Preizkušeni stimulatorji rasti so statistično značilno vplivali na nekatere morfološke lastnosti sadik (višino sadik, maso sadik, število listov in maso korenin) in na nekatere morfološke lastnosti rastlin kolerabice (položaj listov, višina rastline, širina rastline, masa rastline, dolžina kocena, število listov, premer in masa odebeljenega stebla) ter na skupni pridelek kolerabice. Vplivali so tudi na vsebnost vitamina C in nitratov v rastlinskem soku. Stimulator rasti Vita, ki je bil preizkušen na rastlinah na polju in je bil med rastno dobo na rastline apliciran foliarno, ni imel statistično značilnega vpliva na pridelek in morfološke lastnosti kolerabice. V prvem in drugem terminu vrednotenja sadik sta imela največji vpliv na rast in razvoj sadik stimulatorja rasti HB 101 in Agrovit ter njuna kombinacija. Največji vpliv na morfološke lastnosti rastlin na polju je imel stimulator rasti HB 101, v tem obravnavanju je bil prav tako dosežen najvišji tržni pridelek (11,3 t/ha) in najvišji skupni pridelek (14,4 t/ha). At the Faculty of Agriculture of Maribor University, in the years 2006 and 2007 we carried out greenhouse and field trials with the aim to investigate the effects of growth stimulators (Agrovit, Coralit, HB 101, Vita) on the organic production of kohlrabi. For the growth of seedlings we used individual growth stimulators and their combinations. Before sowing, seeds were soaked by HB 101, Agrovit was added to the potting mix, whereas Coralit was sprayed to foliage. The tested growth stimulators had a statistically significant effect on some morphological traits of seedlings (height, weight, number of leaves and root weight) and on some morphological traits of kohlrabi plants (location of leaves, plant height, width and weight, length of stalk, number of leaves, diameter and weight of enlarged stem) and on kohlrabi total yield, as well as effects on vitamin C content and the content of nitrates in the plant sap. Vita growth stimulator used in field trials and sprayed to foliage did not statistically significantly affect the kohlrabi yield and morphological traits. In the first and second evaluation of seedlings, HB 101, Agrovit and their combinations had the most significant effect on the growth and development of seedlings. HB 101 affected morphological traits of plants most significantly and also resulted in the highest market yield (11,3 t/ha) and the highest total yield (14,4 t/ha). kolerabica stimulatorji rasti ekološka pridelava kohlrabi growth stimulators organic production true true false Slovenski jezik Angleški jezik Diplomsko delo 2009-10-23 10:16:10 2009-11-05 12:00:21 2022-04-12 07:20:50 2022-04-19 03:18:43 2009 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:FTQV8ROE VS_Skamlec_Marjeta_2009.pdf VS_Skamlec_Marjeta_2009.pdf 1 8992EFD1D5728E1EDDB8326FFE0FC766 94a4b5c638ca1e6934eb95018efed1d036b682fbc0f171789c831d94f0641f9a 5c4c556b-7c03-11eb-bb7a-00155d0001ca 20.500.12556/dkum/136689e0-17a7-45f7-993b-4a0ed6a2a241 https://dk.um.si/Dokument.php?lang=slv&id=11526 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
