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
