Sažetak
The effects of tillage system and fertilization practice on soybean grain infection with fungi were examined during three year period (2008, 2009 and 2010). Stationary research of reduced soil tillage was conducted, on marsh gley (eugley) hydromeliorated soil type in eastern Croatia. Ten fungal genera were determined: Penicillium, Cladosporium, Aspergillus, Alternaria, Fusarium, Peronospora, Cercospora, Diaporthe, Colletotrichum and Curvularia. The percentage of fungi from genus Diaporthe/Phomopsis in 2010 was 15.06 while in 2008 and 2009 these percentages were significantly lower, 0.89 and 0.18 respectively. The number of Diaporthe/Phomopsis species was significantly higher with reduced tillage and no-tillage compared to conventional tillage and percentage of infected grains increased with the amount of fertilizer (nitrogen). The most important factors affecting the infection level were amount and timing of precipitation and temperature. In those circumstances some soybean pathogens could appear in higher percentage in reduced tillage. In year 2008 with usual amount of precipitation and in extremely dry and hot 2009 there was no significant differences between reduced and conventional tillage and amount of fertilizer in soybean grain infection with important fungal pathogens.
