20.500.12556/DKUM-19966 VPLIV GNOJENJA IN NAČINA OBNOVE RUŠE NA PRIDELEK KRME NA PAŠNIKU The impact of fertilization and sward renovation on forage yield on pasture V letih 2007 in 2008 smo v Zgornjih Hočah (325 m n. v., 49° 37' 31'' s .g. š., 15° 37' 13'' v. g. d.) izvedli poskus na travinju združbe Lolietum perennis, v katerem smo preučevali vpliv gnojenja in načina obnove ruše na pridelek krme na pašniku. Poskus je bil izveden kot dvofaktorski poskus po metodi naključnih blokov v štirih ponovitvah, kjer je bil faktor na glavnih parcelah gnojenje, na podparcelah pa obnova ruše. Gnojenje je potekalo na tri načine: 1 – z gnojevko v količini do 2,5 GVŽ ha-1 in 150 kg ha-1 hiperkorna; 2 – z 20 % nižjimi količinami gnojevke kot v prvem načinu (1,9 GVŽ ha-1) in 150 kg ha-1 hiperkorna; 3 – z mineralnimi gnojili (400 kg ha-1 NPK + 230 kg ha-1 KAN). Pri obnovi ruše so bili izvedeni naslednji načini: 1 – brez obnove (kontrola); 2 – samozasejavanje; 3 – vsejavanje. Različno gnojenje ni signifikantno vplivalo na količino in kakovost pridelka krme v letu 2008, vpliv pa je bil dokazan za načine obnove ruše. Obnova ruše s vsejavanjem, izvedenem v letu 2007, v primerjavi s kontrolo ni povečala pridelka krme v letu 2008, obnova s samozasejavanjem ga je celo zmanjšala. From 2007 and 2008 we carried out the experiment in Zgornje Hoče (325 m n.v., 49° 37' 31'' s.g.š., 15° 37' 13'' v.g.d.) on grassland of Lolietum perennis association, in which we studied the impact of fertilization and sward renovation on forage yield on pasture. The experiment was designed as randomized blocks with four replications, where the factor on main plots was fertilization and on sub-plots sward renovation. Fertilization was carried out in three different ways: 1 – with slurry to 2,5 animal unit (AU) ha.1 and 150 kg ha-1 of ˝hiperkorn˝; 2 – with 20 % less slurry as in treatment 1 and 150 kg ha-1 of ˝hiperkorn˝; 3 – with mineral fertilizers (400 kg ha-1 NPK + 230 kg ha-1 KAN). Sward renovation was carried out by: 1 – without renovation (control); 2 – self-reseeding; 3 – sod seeding. Different fertilizations did not have statistically significant influence on different amounts and quality of forage yield, but otherwise the statistically significant influence was proven for sward renovation. The sward renovation with sod seeding, carried out in 2007, in comparison with control did not give higher forage yields in the year 2008 and the renovation with self-reseeding even reduced the forage yield. gnojenje obnova ruše pašnik pridelek krme pasture fertilization sward renovation yield true true false Slovenski jezik Angleški jezik Diplomsko delo 2011-09-05 14:16:31 2011-09-19 08:24:17 2022-04-13 15:47:26 2023-12-26 03:28:31 2011 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:Z5FPEWTZ UNI_Kmetec_Barbara_2011.pdf UNI_Kmetec_Barbara_2011.pdf 1 2317AFF3CE7479ABF2DC992882D04156 495ebfd97ca808fe76c57cd772adc709e6f79043ba6c9a2c625dd834932e1996 8177e7d3-7c05-11eb-bb7a-00155d0001ca 20.500.12556/dkum/34deb8b4-27bd-4513-bfa0-b4ecd1a7f10e https://dk.um.si/Dokument.php?lang=slv&id=24448 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
