Abstract:V letih 2007 in 2008 smo v Zgornjih Hočah (46°29'31"S, 15°37'13"V, 325m n.v.) ugotavljali vpliv gnojenja na pridelek krme (tri košnje letno) s travnika združbe Lolietum multiflorae. Obravnavanja (različna gnojenja) v poskusu zasnovanem kot naključni bloki v štirih ponovitvah so bila: 1 - gnojenje z gnojevko in hiperkornom - 140 kg N, 120 kg P2O5 in 262 kg K2O ha-1 letno; 2 - enako kot obravnavanje 1 vendar z 20 % nižjimi odmerki gnojil in hranil; 3 - enako kot obravnavanje 1 vendar so uporabljena konvencionalna mineralna gnojila (NPK, KAN). Najvišje pridelke suhe snovi smo tako v letu 2007 (12,60 t suhe snovi ha -1) kot 2008 (13,76 t suhe snovi ha -1) dosegli v obravnavanju 3, podobno je bilo s pridelkom surovih beljakovin (SB) in NEL. Glede na izhodiščno sestavo se je v času izvajanja poskusa v vseh obravnavanjih zmanjšala prisotnost mnogocvetne ljulke (Lolium multiflorum Lam.) in travniške bilnice (Festuca pratensis Huds.) v ruši, povečal pa se je delež latovk (Poa ssp.). Trikosna raba te rastlinske združbe je zaradi pozne košnje in nizke prebavljivosti krme primerna le za ekstenzivno živinorejo.

Title:The impact of fertilization on fodder yield of three cuts of grassland of Lolietum community
Abstract:From 2007 to 2008 we studied the impact of fertilization on fodder yield of three cuts of grassland of Lolietum multiflorae 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: treatment 1 – fertilization with slurry and » hiperkorn « - 140 kg N, 120 kg P2O5, 262 kg K2O ha-1 per year; treatment 2 – same as treatment 1 but with 20 % lower doses of fertilizers and nutrients; 3 - same as treatment 1 but using conventional fertilizers (NPK, KAN). In years 2007 (12.60 t dry matter (DM) ha -1) and 2008 (13.76 t DM ha -1) the highest DM yields were achieved in treatment 3. Treatment 3 resulted also in the highest crude proteins (CP) and net energy lactation (NEL) values. From the beginning to the end of experiment in all the treatments we observed the reduction in annual ryegrass (Lolium multiflorum Lam.) and meadow fescue (Festuca pratensis Huds.) percentages and the increase in the percentage of bluegrasses (Poa ssp.). Our results show that three cuts of this plant community result in low digestibility of fodder, therefore they are suitable only for extensive livestock production systems.
