Organic Production of Spring Oats

This monograph presents the results of researches carried out in oats grown in conditions of organic production obtained by analysing the morphological properties of the plants and chemical properties of the oats. The research was carried out in 2015 and 2016 on 11 oats genotypes of foreign and domestic origin: Krivogashtani Trebenishta Kuchevishte Rajac Slavuj Lovken Kupa Baranja Eksplorer Shampionka and Istra. The results show that the variety Kupa has the lowest plant height among all examined genotypes while the variety Krivogashtani has the highest plants with a height above 100 cm. Since the height of the plant is in a negative correlation with the resistance of the lodging the varieties suitable for breeding are: Kupa Eksplorer Trebenishta and Istra whose height is less than 100 cm. The longest tassel in the period of the two years research have the varieties Lovken and Krivogashtani with 215 cm and 268 cm respetively. The average grain yield per tassel in the two-year research period ranged from 12 g in the Kuchevishte population to 28 g in the Istra variety. The grain yield of oats per unit area grown in conditions of organic production in average.
