| dc.description.abstract | During 2015 and 2016 the research of 11 oats genotypes is conducted, in conditions of organic production. Three of the oats genotypes are domestic populations, Krivogastani, Trebenista and Kuceviste, and the others are introduced varieties: Rajac, Slavuj and Lovken from Serbia, Kupa, Baranja, Eksplorer, Sampionka and Istra from Croatia. The phenological surveys, during the research showed that the vegetation period of the spring oat genotypes, grown in condition of organic production, is 100 – 110 days. The oats was sown in March, and the full maturity was reached in July, in each year of the research. In both years of research, the highest absolute mass of the grain had variety Istra (34,60 g in 2015 and 29,60 in 2016), while, the lowest had the population Krivogastani (12,3 g in 2015 and 14,90 g in 2016). There are very significant statistical differences between the varieties. The hectoliter mass of the grain is statistically different in different varieties, in the both years of the research. Rajac variety showed the lowest hectoliter mass in both experimental years (23,66 kg/hl in 2015 and 31,5kg/hl in 2016). The highest hectoliter mass in 2015 had Istra variety (42,05 kg/hl), and in 2016, it was Krivogastani population (36 kg/hl). The highest oats plants, in both years of research, were Krivogastani population (116,7 cm in 2015 and 143,3 cm in 2016). The lowest plants were Kupa variety (78,3 cm in 2015 and 83,4 cm in 2016). The comparison between varieties showed that there are statistically significant differences. | sr |
