| Se-supplemented fertilization is the main factor affecting the selenium (Se) contents of cereals in Finland. Soil and climatic conditions determine the activity of selenate added to soils and bioavailability to plants. In the present study the Se contents and its variation in Finnish oats, the differences between oat cultivars and cultivation techniques were examined. The selenium (Se) contents of oats (Avena sativa L.) in Finland were examined during 1997-1999 in 3 types of trial: official variety, organic cultivation variety and organic vs. conventional cultivation trials. Farm samples were also examined. The mean Se contents of oats in official variety trials were 0.110, 0.120 and 0.160 mg kg-1 dry weight (dw) range 0.016-0.460 mg kg-1dw in 1997-1999,... |

| ß-Glucan is a beneficial chemical compound in the diet of humans by decreasing the levels of serum cholesterol and blood glucose. The ß-glucan contents of oat groats were studied in official variety trials (1997-1999), nitrogen fertilization trials (1997-1999) and organic variety trials (1997-1998) in Finland. Eight cultivars were studied in the organic variety trials. Two of them, cultivars Puhti and Veli, were cultivated also with a conventional method at the same fields. The years 1997 and 1999 were very warm and dry and 1998 very cool and rainy. The effects of year and cultivar on ß-glucan content were significant in all three trial series. The Kolbu oat cultivar had a significantly lower ß- glucan content than other cultivars in all trials. N... |

| Direct drilling and reduced tillage: - may increase T-2/HT-2 -producers, especially on oats - may decrease DON-producers, especially F. culmorum > is it long lasting effect? - an increase F. avenaceum infection in humid growing seasons - effect on F. culmorum - less f. poae -infection especially on oats -effect on F. graminearum: -not detected, the species is quite common but perithecia are not often detected -F. graminearumis most likely increasing-changes the situation. Control of mycotoxin producers in reduced tillage: -fungicide treatments not effective to control Fusariumand mycotoxins -crop rotation important -resistant cultivars |

| Natural toxins, such as mycotoxins, have emerged as a significant factor affecting the safety image of cereal grains as a raw material for the food and feed industry. The aim of the present study was to investigate the contents of trichothecenes in representative samples of oats during official variety, nitrogen fertilization and organic farming trials in Finland, 1997–1999. Further objectives were to promote industry and commerce by selection of high-quality oat varieties for various applications. The official variety trials conducted at 8–10 locations were managed following standard protocol. There were 2 types of agronomy trial, the first included comparison of oat cultivars grown in conventional and organic farming systems at 6 locations, and the... |

| In Finland compound fertilizers have been supplemented with selenium (Se) since 1984. In 1998, the Finnish Ministry of Agriculture and Forestry raised the Se supplementation level in fertilizers from 6 to 10 mg Se/kg fertilizer. The most important sources of Se are milk, meat, and milk and meat products, which together cover nearly 70 % of the total Se intake. |
