20.500.12556/DKUM-20230 Inkarnatka (Trifolium incarnatum L.) kot prezimni dosevek v kolobarju s koruzo (Zea mays L.) Crimson clover (Trifolium incarnatum L.) as winter catch crop in field rotation with maize (Zea mays L.) V letih od 2009 do 2010 smo v Hočah (275 m n.v., 46° 28' s.g.š., 15° 38' v.g.d.) ugotavljali vpliv inkarnatke (Trifolium incanrnatum L.) na koruzo (Zea mays L.) kot naslednjo poljščino v kolobarju. Poskus je bil zasnovan po metodi naključnih blokov v štirih ponovitvah. V poskuse so bila vključena naslednja obravnavanja: kontrola (brez prezimnega dosevka), mnogocvetna ljuljka (Lolium multiflorum Lam.) in inkarnatka, po katerih je bila koruza gnojena s 120 kg N ha-1, ter inkarnatka, po kateri je bila koruza gnojena s 60 kg N ha-1. Dosevki so bili sejani konec avgusta 2009, zelinje dosevkov pa je bilo spravljeno z njive konec aprila 2010, nakar je bila njiva preorana in posejana koruza. V poskusu se je inkarnatka izkazala kot zelo dober predposevek koruzi, kar se je izkazovalo v največji doseženi višini koruze, največjem pridelku sušine koruze in največji vsebnosti dušika v pridelku koruze. V obravnavanju, kjer smo po inkarnatki koruzo pridelovali ob zmanjšanem gnojenju z dušikom, je bil pridelek koruze še vedno statistično na istem nivoju kot v kontrolnem obravnavanju, kjer je bila koruza gnojena s 120 kg N ha-1. Pozitiven vpliv inkarnatke na koruzo kot naslednjo poljščino v kolobarju lahko pripišemo simbiotski vezavi dušika pri inkarnatki, kar omogoča vnos dodatnega dušika iz zraka v krogotok dušika v njivskem kolobarju. In the years from 2009 to 2010 in Hoče (275 m a.s.l., 46° 28' N, 15° 38' E) we investigated the impact of crimson clover (Trifolium incarnatum L.) on maize (Zea mays L.) as the subsequent crop in field crop rotation. A randomized block design with four replications was applied. Field trials included the following treatments: control (without winter catch crop), ryegrass (Lolium multiflorum Lam.) and crimson clover after which the maize was fertilized with 120 kg N ha-1 , and crimson clover after which the maize was fertilized with 60 kg N ha-1. Catch crops were seeded at the end of August 2009, green mass of catch crops was harvested at the end of April 2010, then the field was ploughed and the maize seeded. Crimson clover was found to be a very good catch pre-crop in rotation with maize, which was reflected in the highest obtained height of maize, the highest dry matter yield, and the highest nitrogen content in maize crop. The statistical analysis showed that the maize yield in the treatment with 60 kg N ha-1 was still at the same level as in the control where the maize was fertilized with 120 kg N ha-1. The positive effect of crimson clover on maize as the next crop in crop rotation can be attributed to symbiotic fixation of nitrogen with crimson clover which enables the input of additional nitrogen from the air into the cycling of nitrogen in the field rotation. prezimni dosevek / inkarnatka / mnogocvetna ljuljka / koruza / pridelek catch crop / crimson clover / ryegrass / maize / yield true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-09-13 14:24:01 2011-10-12 09:59:52 2022-04-14 07:44:32 2023-12-27 03:10:56 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:7FPGE45R UNI_Kuhar_Sandra_2011.pdf UNI_Kuhar_Sandra_2011.pdf 1 CE8D9D1A5F3A03BF533386253B0A31D9 6af49e48f0ce6272fa3eede89150b469abd2d27bef04ed4eb55a1ba7ca385df8 8d11e832-7c05-11eb-bb7a-00155d0001ca 20.500.12556/dkum/252d8404-a973-46e7-8b2d-65fd858500be https://dk.um.si/Dokument.php?lang=slv&id=24918 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
