The impact of tillage and fertilization on wheat grain infection

During two years period (2008 and 2009) effect of tillage and fertilization on fungal infection of wheat grain was examined. Research of different soil tillage was conducted at marsh gley (hipogley) hydromeliorated soil type in eastern Croatia. Twelve fungal genera were determined: Fusarium, Alternaria Cladosporium, Penicillium, Epicoccum, Septoria, Helminthosporium, Acremonium Trichotecium, Gonatobotrys, Mucor and Aspergillus. Regardless of the year, tillage and fertilization, majority of fungi were from Alternaria genus, but there were not significant differences in incidence of Alternaria sp. between treatments. A significantly higher grain contamination with Fusarium sp. was found in the no-tillage system in 2008 and reduced system tillage in 2009. Nitrogen fertilization treatments did not significant influenced of the fungal populations.
