AB  - Research was carried out on mountain Kopaonik, on two associations Danthonietum calycinae (1000 and 1500 m above sea level), in the period from year 2003 to 2004. Production of grassland depending on the fertilization (1. no fertilization, 2. N60P30K30, 3. N80P30K30, 4. N100P30K30), and cutting schedule (I forming of panicles, II beginning of spike forming and III full spike forming) was monitored. Production of grassland and floristic composition demonstrated dynamic changes depending on the year, cutting schedule and applied fertilization treatments. The greatest production of grassland dry mass and crude proteins on both locations was obtained in late cutting, i.e. in the stage of full spike forming of dominant species and in fertilization treatment with N80P30K30. Grassland was transformed by fertilization from ass. Danthonietum calycinae into ass. Festucetum rubrae on both locations.
AB  - Istraživanja su izvršena na Kopaoniku u dve sastojine asocijacije Danthonietum calycinae (1000 lokalitet Šapido i 1500 m.n.v. lokalitet Marinkovac) u periodu od 2003-2004. godine. Postavljen je dvofaktorijalni poljski ogled gde je prvi faktor bio đubrenje (1. bez đubrenja (kontrola), 2. N60P30K30, 3. N80P30K30, 4. N100P30K30), a drugi rok kosidbe (I vlatanje, II početak klasanja i III puno klasanje dominantnih vrsta). Produkcija travnjaka i floristički sastav su pokazali dinamičke promene u zavisnosti od godine, rokova kosidbe i primenjenih tretmana đubrenja. Najveća prosečna produkcija travnjaka na oba lokaliteta dobijena je kasnijom kosidbom travnjaka, odnosno u fazi klasanja dominantnih vrsta. Đubrenjem je povećana produkcija travnjaka, a najbolji učinak je imao tretman N80P30K30, 44,7% u prvoj i 111,3% u drugoj godini na lokalitetu Šapido, odnosno, 46,7% i 131,4% na lokalitetu Marinkovac. Povećanje količine N od N80 na N100 na fonu P30 i K30 je dovelo do smanjenja produkcije na oba lokaliteta. Prinos sirovih proteina ima sličnu tendenciju kao i prinos suve mase. Najveći prinos sirovih proteina je ostvaren na tretmanima sa najvećom količinom N i to prosečno u obe godine 568,1 kgha-1 u drugom roku kosidbe na lokalitetu Šapido i 552,3 kgha-1 u trećem roku kosidbe na lokalitetu Marinkovac. Floristički sastav se menjao po godinama u zavisnosti od meteoroloških uslova. Đubrenjem je smanjen broj vrsta. Smanjeno je učešće vrste Danthonia calycina, a povećano učešće vrste Festuca rubra i Agrostis vulgaris. Travnjak je transformisan iz ass. Danthonietum calycinae u ass. Festucetum rubrae na oba lokaliteta.

AB  - Harvest index is an important indicator of seed production efficiency. Its importance is related to dramatic increases of crop yields that occurred in the twentieth century. Harvest index reflects distribution of photosynthates between the grain and the vegetative part of the plant, as well as carbon allocation in grain crop. In an experiment with red fescue and redtop, grain yield in different inter-row sowing distances (20, 40 and 80 cm) in the first and in the second year was observed. Also, production of dry matter through two swaths was measured. Grain yield, as economic, and total biomass, as biological yield were put in relation giving harvest index expressed in percents. Values ranged from 6,98 to 14,76% for red fescue and from 3,01 to 7,93% for redtop.

AB  - Results of researches carried out over the long period regarding the effect of phosphorus fertilizers on change of natural and artificial (sowed) grasslands in hilly-mountainous regions of Serbia are analyzed in this paper. It was concluded that without the phosphorus higher biological production can not be achieved. However, it is of great importance to realize correct ratio between this nutrient and nitrogen and potassium, not only in order to achieve better efficiency, but also more rational use of mentioned nutrients. This ratio depends on the type of the natural grassland or leguminous-grass mixture, focusing on the leguminous species, if they are present and in which proportion. If leguminous plants are present on natural grasslands, phosphorus fertilizers, with or without potassium contribute to the increase of their presence. Also, they induce increase of yield, however in the absolute value yields are not high. Higher quantities of phosphorus fertilizer affect the increase of yield, but only if leguminous plants are present in floristic composition. Different response of species from the Fabaceaea and Poaceae families is registered in double fertilizing combinations. On natural grasslands, treated with PK, yield is always lower if there are no leguminous plants present, and if they are present the yield is lowest on grasslands treated with NK. Also on artificial (sowed) grasslands, P and PK treatments stimulate the growth of leguminous components. If also nitrogen is introduced, especially in higher quantities (over 50 kgN/ha) leguminous plants are suppressed from the mixture. It is recommended in years when leguminous plants are present in projected quantities or more, to use PK or smaller quantities of N fertilizer, and when leguminous are absent to give advantage to the nitrogen. This is based on research results which demonstrate that in the first and second year higher yields of leguminous-grass mixtures are obtained on treatment with P80K80 than N80P80K80 (2,86 compared to 1,74 and 9,05 compared to 8,87 t/ha of dry mass).
AB  - Navedeni su brojni rezultati istraživanja uticaja fosfornih đubriva na florističke promene, botanički sastav i prinos prirodnih i sejanih travnjaka u brdsko-planinskom području Srbije.Prirodni travnjaci su floristički složene zajednice ali su im prinosi vrlo niski (1,8 t/ha livade i 0,5 t/ha pašnjaci). Fosforna đubriva sama ili u kombinaciji sa kalijumovim utiču na povećanje udela leguminoza ako ih ima u sastavu. U tom slučaju utiču i na povećanje prinosa. Đubrenje travno-leguminoznih smeša samo sa PK doprinosi povećanju udela leguminozne komponente. Zahvaljujući tome unošenje P80K80 u prve dve godine obezbeđuje veće prinose od primene N80P80K80. Dok u smeši ima leguminoza (>20%) preporučuje se PK đubrenje, a kada leguminoza nema ili su nestale iz smeše prednost se daje azotnom đubrivu.
