Black Oat (Avena Strigosa Schreb.) Ontogenesis And Agronomic Performance In Organic Cropping System And Pannonian Environments

This study examined the influence of agroecological conditions on the ontogenesis and production yield traits of black oat (Avena strigosa Schreb.). Understanding the agronomic and phenological properties related to productive properties of black oats can enable more successful introduction into new areas of oat cultivation. Field microexperiments were performed during the three consecutive years (2017-2019) on the two localities in South Banat, in Serbia, which differed in soil type: carbonate chernozem and humogley, respectively. The results showed that all investigated traits of oat in the chernozem soil type were higher when compared with measured traits obtained from the humogley soil type. The average value of yields of aboveground biomass, yield and protein content were significantly higher in relation to the humogley, by 13%, 17% and 11%, respectively for all three seasons. Observed by years, all productivity parameters differed significantly, which confirmed that the productivity of the cultivated plants was strongly influenced by different agroecological, soil and climatic conditions in Pannonian environments. The aboveground biomass and grain yield obtained from the humogley soil type indicate that this species can be successfully grown and utilized in production as a cover or fodder crop even in less favorable soil conditions.
