QUALITATIVE FEATURES OF OATS GROWN IN CONDITION OF ORGANIC PRODUCTION

Abstract

The research was conducted in 2015 and 2016, at 11 oats genotypes in terms of organic production. Three of the studied genotypes were domestic populations: Krivogashtani , Trebenishta and Kuchevishte . The rest were introduced varieties, including Rajac , Slavuj and Lovken from Serbia and Kupa , Baranja, Eksplorer , Shampionka and Istra from Croatia. On average, for both years, the variety Shampionka had the highest protein content (14.80%), which indicates that the grain has a high nutritional value. There is a statistically significant difference between the examined genotypes. The percentage of fat in oats, grown organically, in both years of research is statistically different at different genotypes. On average, in both years of research, the fat content ranged from 2.31% in the population Trebenishta , up to 4.47% in the population of Krivogashtani . The variety Baranja is with the highest ash content in the grains (4,35%) in average, for the period of research. In the same group a , is ranked variety Shampionka , with 4.30%. Between genotypes there is a statistically significant difference. For the period 2015-2016, all examined genotypes belong to group a , that is, all varieties and populations contain high cellulose content. Given that the property cellulose content is negatively correlated with the quality of oats, in plant selection, varieties with lower cellulose content are more important. Analysis of variance for the quality of oats grain shows that the content of protein, fat and ash values are relatively constant in the years of the research. The conditions in the years of research had a weaker effect than the genotype. The strength of the genotype is 65.06%, 67.06% and 72.04%, respectively. The properties content of protein, fat and ash are strongly influenced by the genotype while the cellulose content is strongly influenced by the year.
