Abstract

The influence of previous crops (oat, maize, or rape) and six variety of hulled oats (Avena sativa L.) were assessed qualitatively and quantitatively as to yield, thousand grain weight, and grain size in observations from 2009 to 2012. Harvested grain samples were analysed for the presence of mycotoxins (T-2 and HT-2 toxins, deoxynivalenol, and nivalenol) using LC/MS–MS. Fusarium poae was the species most often found on oats. Flamingsprofi and Salo were the most sensitive varieties of oat. The sensitivity of the variety to lodging as well as the earliness of the variety was correlated with the occurrence of fusariosis on oats. The highest average occurrence of Fusaria on oat grains was after use of maize as the pre-crop. The oat samples were most often contaminated with nivalenol. Nivalenol positively correlated with the weight of a thousand grains of oat and negatively correlated with the oats grain falling through the sieve.
