Abstract:Poljski poskus je bil izveden na UKC — Pohorski dvor in KPD — Rogoza. Potekal je od avgusta 2004 do aprila 2005. Poskus je bil postavljen po split-plot metodi v štirih ponovitvah. Glavne parcelice so predstavljale prezimne dosevke, podparcelice pa čas setve le-teh. Proučevan je bil vpliv časa setve (sredini avgusta, sredina septembra in sredina oktobra) na rast in razvoj, količino simbiotsko vezanega in akumuliranega dušika v rastlinah ter mineralnega dušika v tleh petih prezimnih dosevkov (mnogocvetna ljuljka, podzemna detelja, inkarnatka, črna detelja in ozimna grašica). Čas setve je statistično značilno vplival na vse proučevane parametre. Zgodnji rok setve (sredina avgusta) se je izkazal, kot najboljši in je torej ključnega pomena za dober in kakovosten pridelek, kakor tudi zadovoljivo količino simbiotsko vezanega in akumuliranega dušika, ki bo ob zaoravanju na voljo naknadno sejani poljščini. Zelo pozen rok setve (sredina oktobra) pa ni več primeren za setev prezimnih dosevkov iz družine metuljnic. Med proučevanimi prezimnimi dosevki so se kot najuporabnejše izkazale ozimna grašica, podzemna detelja in inkarnatka.

Title:COMPARISON APPLICABILITY OF CERTAIN PLANTS AS WINTER COVER CROPS
Abstract:The field experiment was conducted between August 2004 and April 2005 at UKC Pohorski dvor and KPD Rogoza. The experiment was designed as a split – plot in four replicates. The main plots represented winter cover crops and the subplots represented the sowing date. The effects of late summer (mid August), early autumn (mid September) and late autumn (mid October) sown winter cover crops (Italian ryegrass, subterranean clover, crimson clover, red clover and winter vetch) on the quantity of symbiotic fixed and accumulated nitrogen in plants and in soil was observed. The sowing date significantly influenced all observed parameters. The amount of all observed parameters by winter cover crops sown in September were significantly lower than those sown in August, whereas the late autumn sowing date was less suitable for the legumes. Among the observed winter cover crops the most useful were winter vetch, subterranean clover and crimson clover.
Keywords:nitrogen accumulation, sowing date, soil mineral nitrogen, making green of the ground, winter cover crop (italian ryegrass, subterranean clover, crimson clover, red clover, winter vetch), yield, symbiotic nitrogen fixation.
