Cilj ovog istraživanja bio je utvrditi utjecaj obrade tla i gnojidbe dušikom na pojavu Fusarium vrsta na zrnu pšenice. Poljski pokus je bio postavljen na lokaciji Magadenovac u razdoblju od rujna 2013. godine do lipnja 2014. godine, u 5 varijanti obrade tla te 3 varijante gnojidbe dušikom. Prisustvo Fusarium vrsta je utvrđeno u svim ispitivanim varijantama obrade tla i gnojidbe. Pri gnojidbi dušikom u smanjoj dozi zaraza Fusarium vrstama bila je statistički značajno manja u odnosu na tretmane sa preporučenom i povećanom dozom gotovo u svim varijantama obrade tla (konvencionalna, tanjuranje i no till). Pri povećanoj gnojidbi dušikom najveći broj zaraženih zrna utvrđen je u varijanti tanjuranja i podrivanja, The aim of this research was to determine the impact of tillage and nitrogen fertilization treatments on the occurence of Fusarium species on the wheat grain. The field experiment was set at the Magadenovac site from September 2013 to June 2014, having five variants of tillage treatments and three variants of nitrogen fertilization treatments. The presence of Fusarium species was determined in all tested variants of tillage and fertilization treatments. During the fertilization with reduced amount of nitrogen, the infection with Fusarium species was greatly reduced statistically in comparison with other treatments with recommended and increased amount in almost all variants of tillage treatments (CT-conventional tillage treatment, DH- disk harowing and NT- no-till treatment). During the fertilization that had an increased amount of nitrogen, the greatest number of grain infection was determined in the disk harowing and subsoiling variants.

Cilj ovog istraživanja bio je utvrditi pojavu Fusarium vrsta na zrnu pšenice pri različitim varijantama obrade tla i gnojidbe tijekom 2013./2014. godine. Pokus je postavljen na lokalitetu Čačinci u 5 varijanti obrade tla i 3 varijante gnojidbe dušikom. Utvrdili smo prisustvo vrsta iz roda Fusarium na zrnu pšenice u svim ispitivanim varijantama obrade tla i gnojidbe. Pri gnojidbi dušikom u preporučenoj i višoj dozi zaraza zrna fuzariozama je bila statistički značajno veća nego u tretmanima sa smanjenom gnojidbom u različitim obradama tla (konvencionalna obrada, podrivanje, no till). Pri smanjenoj gnojidbi dušikom najveći broj zaraženih zrna utvrđen u varijanti CH (rahljenje) i DH (tanjuranje), dok je najmanji broj zaraženih zrna utvrđen u konvencionalnoj obradi tla (CT) i podrivanju (SS) te u izostavljenoj obradi tla (NT)., The aim of the study was to determine the occurrence of Fusarium species on wheat grain under different tillage and fertilization treatments during 2013/2014 season. The experiment was set up at Čačinci site with 5 tillage and 3 nitrogen fertilization treatments. The presence of Fusarium species was recorded on wheat grains in all tillage and fertilization treatments. Infection of wheat grains with Fusarium species was statistically higher in treatments with nitrogen fertilization at the recommended and higher rate than in treatments with lower fertilization rate in different tillage systems (conventional tillage, subsoiling, no till). In treatments with lower nitrogen fertilization the largest number of infected seeds was found in CH (chiseling) and DH (disk harowing) tillage systems, while the lowest number of infected seeds was determined in conventional tillage (CT), subsoiling (SS) and no-till (NT) treatments
