SPASOVA, D., S.MITREV, A. STOILOVA, D. SPASOV and R.KUKUTANOV, 2010. Content of raw proteins in oat depending on the growing system in Strumica region, Macedonia. Bulg. J. Agric. Sci., 16: 673-677
In the period 2005-2007 examinations were conducted with five populations of oat (Krivogastani, Trebenista, Radolista, population from Bulgaria and Kuceviste) and three oat varieties (Rajac, Slavuj and Lovken), which were set in conditions of organic and conventional production. The growing system showed increase in the content of proteins under the organic production system, absolutely by 0.18 %, or relatively by 1.39 % in comparison
with the conventional production system. In the conditions of organic production the highest average content of proteins was found for the population Trebenista (13.74 %), and the smallest for the population Kuceviste and Slavuj variety (12.43 %), which was absolutely by 1.31 % or relatively by 10.54 % more. In the conditions of conventional production the highest average content of proteins was found for the population Trebenista (13.29%), and the smallest (12.31 %) for the Bulgarian population.
