Black Oat (Avena strigosa Schreb.) Ontogenesis and Agronomic Performance in Organic Cropping System and Pannonian Environments

Abstract

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.

Effects of Liming and Nutrient Management on Yield and Other Parameters of Potato Productivity on Acid Soils in Montenegro

“…The systematic fertilization with organic fertilizers on these soils neutralizes their acidity, increases the nutrient content and improves the adsorptive properties. All of this together affects the improvement of the physical and chemical properties of these soils [43][44][45][46][47][48]. The main conclusion of this research is that the integrated use of liming, farmyard manure and mineral fertilizers can provide economical and environmentally friendly production of potatoes on a significant part of acidic soils in the mountainous regions of Montenegro.…”

Financial Crisis and Its General Impact on Developments Within the Banking Sector of Bosnia and Herzegovina

“…The economy in these countries relies heavily on very heterogeneous legal entities [8][9][10][11][12][13][14][15], which largely determines the business of a large number of heterogeneous companies [16][17][18][19][20][21][22][23][24] whose existence requires positive business in continuity in order not to fall into losses.…”

Risk Evaluation in the Business of Medium-Sized Companies on the Example of the Republic of Serbia

“…Management tries to consider as many risk factors as possible in the investment evaluation process that can have an impact on the overall business of the company [17][18][19][20][21]. Fair compensation of possible risks to the company's operations can also have a positive effect on new (future) investments [22][23][24][25]. This is important to point out due to the fact that good and honest financial reporting can reduce the distrust and antagonism of shareholders and other creditors who invest in the company's operations.…”
