Abstract:V letih od 2007 do 2008 smo v Zgornjih Hočah (325 m n.v., 46°29' 31'' s.g.š., 15° 37' 13'' v.g.d.) ugotavljali vpliv gnojenja na pridelek krme s štirikosnega travnika združbe Lolietum. Poskus je bil zasnovan po metodi naključnih blokov v štirih ponovitvah. V obravnavanju 1 smo uporabili gnojevko od 2,5 GVŽ ha-1 in 48 kg P2O5 ha-1 (gnojilo hiperkorn) , v obravnavanju 2 pa smo ob istih gnojilih kot v obravnavanju 1, uporabili za 20 % manjše količine hranil. V obravnavanju 3 je bila vsebnost dodanih hranil primerljiva obravnavanju 1, le da so bila dodana hranila iz mineralnih gnojil. Najvišje pridelke sušine smo v letu 2007 pridelali v obravnavanju 1 (12,05 t ha-1), najnižje pa v obravnavanju 2 (9,46 t ha -1). Naslednje leto med obravnavanji ni bilo statistično signifikantnih razlik. Pri vrednotenju kakovosti krme so bile razlike med pridelki posameznih obravnavanj statistično signifikantne le pri večjih, do 20 odstotnih tveganjih. Rezultati nakazujejo na to, da so na male razlike med obravnavanji vplivali drugi dejavniki, kot je npr. intenzivna raba ruše in gnojenje v predhodnih letih. Zato bi bilo o dejanski vrednosti posameznih obravnavanj potrebno dolgoletno izvajanje poskusa.

Title:The impact of fertilization on fodder yield of four cuts of grassland
Abstract:From 2007 to 2008 we studied the impact of fertilization on fodder yield of four cuts of grassland of Lolietum plant community in Zgornje Hoče (325 m a.s.l., 46°29' 31'' N, 15° 37' 13'' L). The experiment was designed as randomized blocks with four replications. In treatment 1 we used slurry from 2.5 AU ha-1 and 48 kg P2O5 ha-1 (hypercorn fertilizer) and in treatment 2 we used 20 % less nutrients while using the same fertilizers as in treatment 1. In treatment 3 the amount of added nutrients was comparable to treatment 1, only that also mineral fertilizers were added. In 2007 the highest DM yield was produced in treatment 1 (12.05 t ha-1) and the lowest in treatment 2 (9.46 t ha-1). In the second year of experiment no statistically significant differences were observed. When evaluating the quality of fodder, the differences in yield from individual treatments were statistically significant only with higher-up to 20 % level of significance. The results indicate that other factors, such as intensive use of turf and fertilization in previous years, resulted in smaller differences in treatments. Therefore, more research will be needed to more accurately evaluate the results of individual treatments.
