Abstract

Divljač je prema lovnom zakonodavstvu dobro od interesa za Republiku Hrvatsku, a kvalitetna trofejna divljač značajan gospodarski resurs. Kvalitetna hrana uz dobre genetske predispozicije, omogućuje postizanje vrijednih trofeja divljači što uvećava gospodarski značaj lovišta. Uključivanjem mahunarki u sustav jednogodišnjih remiza ostvaruje se znatna ušteda u gnojidbi mineralnim dušičnim gnojivima te postizanje zadovoljavajućih prinosa i kakvoće krme za potrebe prehrane divljači u lovištu. Istraživanja su provedena na poljoprivrednim površinama u državnom otvorenom lovištu broj X/11 „Suhopoljska Bilogora“ u cilju utvrđivanja prinosa suhe tvari i hranidbene vrijednosti krme jarog graška cv. Lessna i facelije cv. Ballo. Najveći prinos suhe tvari (6,33 t ha-1), sadržaj sirovih bjelančevina (186 g kg-1) i prinos sirovih bjelančevina (1 177 kg ha-1) imao je jari grašak cv. Lessna na najvećoj razini gnojidbe dušikom (160 kg ha-1). Najveći prinos suhe tvari (6,93 t ha-1) i prinos sirovih bjelančevina (776 kg ha-1) imala je facelija cv. Ballo također na najvećoj razini gnojidbe dušikom (160 kg ha-1). Najmanji sadržaj kiselih deterdžent vlakana (286 g kg-1) i neutralnih deterdžent vlakana u suhoj tvari (393 g kg-1) imao je jari grašak cv. Lessna na razini gnojidbe dušikom (40 kg ha-1). U fazi pune cvatnje facelije cv. Ballo sadržaj kiselih i neutralnih deterdžent vlakana u suhoj tvari je bio veći u odnosu na jari grašak cv. Lessna i to na svim razinama gnojidbe dušikom.

Abstract (english)

Game animals are designated in the Republic of Croatia hunting legislation as an asset of national interest, and a quality game in trophy value is important economic resource. Beside genetic predisposition, quality food provide achivement of high trophy values in game animals, which enlarge economical benefit of the hunting ground. The inclusion of legumes into the feeding system of hunting game provides substantial savings in expensive mineral nitrogen fertilization and the achievement of satisfactory yields and quality of forage as game food in the hunting ground. Research were carried out on agricultural land in the state open hunting area number X/11 "Suhopoljska Bilogora" in order to determine the yield of dry matter and nutritive value of spring peas cultivar Lessna and fiddleneck cultivar Ballo. The highest yield of dry matter (6.33 t ha-1), the content of crude protein (186 g kg-1 dry matter) and the yield of crude protein (1 177 kg ha-1) had a spring peas cultivar Lessna at the highest level of nitrogen fertilization (160 kg ha-1). The highest yield of dry matter (6.93 t ha-1) and crude protein (776 kg ha-1) had the fiddleneck cultivar Ballo also at the highest level of nitrogen fertilization (160 kg ha-1). The lowest content of acidic detergent fibers (286 g kg-1) and neutral detergent fibers in dry matter (393 g kg-1) had a spring peas cultivar Lessna on level of nitrogen fertilization (40 kg ha-1). In the stage of flowering the fiddleneck cultivar Ballo content of acidic and neutral detergent fibers in the dry matter was higher in relation to spring peas cultivar Lessna and that at all levels by fertilizing nitrogen.
