Participation of elements of cropping in the forming of the crop of glumiferous oats grown using traditional and organic systems.

Summary A one factor field experiment was carried out under the Beskid Niski mountain conditions in order to determine the impact level of yielding components on differences in yields of glumiferous oats cultivated in a traditional and organic system. The obtained results showed that the number of panicles had the greatest impact on differences in grain yields of oats grown using the two studied systems. The impact of this element was 61.4%, which was almost three times greater than that of the mass of a thousand grains. Of all the components of grain yield structure, the quantity of grains in a wisp had the lowest impact on the decrease in the grain yield of oats cultivated in the organic system compared to the traditional system; this impact was 18.2%. An average grain yield of oats grown in the organic system was ca. 10% lower than that of oats grown in the traditional system.
