The impact of tillage and fertilization on infection of wheat grains

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 podrivanjaThe 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
