EXAMINATION OF SOME QUALITY FEATURES OF OATS GROWN IN CONDITIONS OF ORGANIC PRODUCTION

Abstract

The research was conducted in 2015 and 2016, at 11 oats genotypes in terms of organic production. Three of the populations were domestic: Krivogastani, Trebenista and Kuceviste. The rest were introduced varieties, including Rajac, Slavuj and Lovcen from Serbia and varieties: Kupa, Baranja, Explorer,Sampionka and Istra from Croatia.

In the first year of the study, the energy of germination of oats seed ranged from 70% in variety Rajac, up to 96% for the variety Kupa. In the second year of the study, the energy of germination was 81% for the variety Kupa, to 96% in variety Istra.Compared between varieties, it is pointed out that there are statistically significant differences.

The total germination of oat seeds, cultivated under conditions of organic production, is statistically different between different genotypes, in both years of research. In 2015, the variety Rajac showed minimum germination (70%), and in 2016, the variety Lovcen (82%).Variety Krivogastani showed the greatest over all germination in both experimental years (96% in 2015 and 97% in 2016).

Regardless the year and the mode of production, the best genotype of the tested variants for the highest absolute mass of grain, it proved the variety Istra with 34,6g in 2015 and 29,6g in 2016. The smallest absolute mass in both experimental years had the Krivogastani population, 12.3g in 2015 and 14.9g in 2016.There is statistically significant difference between varieties.
