AB  - Soil organic carbon plays an important role in a long-term agroecosystem productivity, in the global C cycle, maintaining a soil nutrient pool and improving its availability. The objective of this study is the assess the impacts of long–term cropping practices on SOC dynamics in Slovakia and Serbia. Soil C sequestration is a complex process that is influenced by many factors, such as agricultural practice, climatic and soil conditions. For the both location the initial SOC decline was followed with the C stabilization and possible increase where proper practices were used. More intensive crop management systems that maintained residue cover provided the greatest benefit towards increasing the quantity of mineralizable nutrients within the active fraction of soil organic carbon (SOC), as well as increasing C sequestration as SOC. Long–term field experiments have contributed significantly to our current knowledge of soil quality and have been used to study the influence of crop management, fertilizer application and tillage practices on SOC content.

AB  - Effects of Azotobacter chroococcum inoculation on sugar beet production characteristics and microbiological status in the soil were studied on three different methods of sugar beet inoculation with Azotobacter chroococcum strains. The variety Drena was used in the study. Experiments were carried out at Rimski Sancevi in 2008, 2009 and 2010. Five strains of Azotobacter chroococcum were used as microbial inoculants. Three inoculation methods were applied: (A) strain incorporation into the soil before planting, (B) strain application on soil surface before the first inter-row cultivation and (C) seed inoculation before planting. All five Azotobacter chroococcum strains, in each of the three application methods, showed a positive effect on the production characteristics of sugar beet. The highest yield increases in root (6.45 t ha(-1)) and sugar (0.63 t ha(-1)) was obtained on seed inoculated with strain 10.

AB  - The aim of this study was to detect the most harmful weeds in the canopies of sugar beet during the years 1999-2009 in the Slovak Republic. The actual weed infestation was evaluated by a counting method per square. The four randomly established sample quadrants were situated minimally 20 m from field margin and apart each other, respectively. Temporal dynamics of all weed species in the canopies of sugar beet were statistically analyzed. In the sugar beet fields the most problematic weeds were: perennial weed (Cirsium arvense(L.) SCOP, Elytrigia repots (L.) DESV, Convolvulus arvensis (L.)), annual weeds (Chenopodium spp. Amaranthus spp., Atriplex spp., Persi-caria spp., Echinochloa crus galli (L.) BEAUV., Datura stramonium (L.), Mercurialis annua (L.), Panicum capillare (L.), lea xanthiifolia Nun.) and cultural crops winter oilseed rape (Brassica napus (L.)). Temporal dynamics of actual weed infestation depend on climate conditions of production region, forecrop and canopy health condition. The most dangerous weed species were Persicaria spp., Amaranthus spp., Atriplex spp., Chenopodium spp. and Echinochloa crus galli (L.)P.BEAUV, which infested more than 90 % of sugar beet fields in maize and sugar beet production region.

AB  - A seven year field study was conducted in south-western Slovakia to investigate the effects of different soil tillage intensities and crop rotation patterns on weed density, weed species composition and diversity, and weed competition in maize. Maize was grown in four different crop rotations with three different soil tillage systems (conventional ploughing, 0.3 m depth; offset disc ploughing, 0.15 m depth; shallow loosening, 0.1 m depth). Dominant weed species were Amaranthus retroflexus L., Chenopodium album L., Echinochloa crus-galli (L.) P.Beauv., Convolvulus arvensis L. and Cirsium arvense (L.) Scop. Conventional tillage reduced weed density significantly, primarily through the reduction of perennial weeds. Significantly lower weed dry biomass was observed under conventional ploughing than under reduced tillage by offset disc ploughing or shallow loosening. Crop rotation did not have a significant influence on species richness as indicated by the Margalef's index. However, there was significantly higher total weed density in continuous maize cropping (38.5 plants m-2) than when maize was grown in rotation with spring barley (28.6 plants m-2) or in rotation with peas and winter wheat (25.8 plants m-2). Primary tillage systems had a more significant effect on the composition of the weed flora, weed density and diversity, and weed biomass than did crop rotation patterns.
