POSSIBILITIES OF WINTER CROP GRAIN’S QUALITATIVE INDICES RISE FOR BIOETHANOL PRODUCTION

Bioethanol production is one of cereal’s using ways. COM 2003/30/EC: Directive on the promotion of the use of biofuels or other renewable fuels for transport orders that proportion of biofuels in 2010 must be -5.75% but in 2020 – 10%. The object of research is to study the influence of winter crops cultivation’s technology on quality of grain and suitability for bioethanol production. Field research was organized in the Agricultural Science Centre of Latgale from 2005 to 2008. There were researched 5 fertilizer rates and the influence of varieties on the grain yield and starch in the experiment for 3 years. Starch content, yield and the result of bioethanol have changed depended on species of cereals, varieties, growing year and fertilizer rate. It is recommended to use good quality grains with high starch content and low protein content for bioethanol production.
