The paper describes the biological properties and agronomic efforts of herbicide weed management possibilities of important cocklebur species found in Slovakia. These include the common cocklebur Xanthium strumarium L. as well as hunter burr Xanthium riparium Itz. et Her. em. Lasch. both are widely spread species occurring mainly on arable land especially in row crops; the third one prickly burweed Xanthium spinosum L. is still rare and mainly occures in meadows and pastures – all three are poisonout species with an increasing importance mostly in southern regions of the country where sugar beet is planted as well. © 2016, Listy Cukrovarnicke a Reparske.

This work presents information on rating and financial evaluation of environmental soil potential indexes (ESPI). These indexes enable identification of relatively homogenous spatial units with the specific soil capacity to provide for its individual environmental functions. The ESPI four-digit code expresses the degree of capacity of the soil to accumulate water, to immobilize the risk elements and substances and to transform risk substances (organic pollutants). In agricultural soils of Slovakia 493 combinations of environmental soil potential index were found. Each index is expressed through rating (point) value and financial value. The average value of the Slovak agricultural land to provide for selected ecological soil functions is 55.3 points, which in financial expression represent 35.946 billion € for agricultural land or approximately 1.42 € per square metre. © Geografický ústav SAV / Institute of Geography SAS.

This work evaluates the results of direct effect of HUMAC Agro on yield and sugar content of sugar beet as well as on selected soil properties in a field trial established in soil-climatic conditions of south Poland in 2013 (vegetation season: average air temperature 16.0˚C, total precipitations 261 mm). Soil conditioner HUMAC Agro was applied to middle heavy pseudopodzolic soil in early spring of 2013 in two dosages: 500 kg ha-1 in case of Variant 1 (V1) and 250 kg ha-1 in case of Variant 2 (V2); it was not applied in case of Variant 3 (V3). Nitrogen fertilization according to Variants: 60.3 kg ha-1 N for V1, 94.8 kg ha-1 N for both V2 and V3. Doses of phosphorus, potassium and sulphur were the same for all Variants. V1 achieved the highest sugar beet yield 95.97 t ha-1 with sugar content 18.12% which meant the highest sugar yield 17.39 t ha-1(+29.6% more than control treatment). V2 achieved sugar beet yield 86.39 t ha-1 with the lowest sugar content 17.65% and sugar yield 15.25 t ha-1 (+13.6% more than control treatment). The control treatment achieved the lowest sugar beet yield 72.81 t ha-1with the highest sugar content 18.43% and the lowest sugar yield 13.42 t ha-1. Soil conditioner HUMAC Agro also influenced soil properties. After the application of 500 kg ha-1 HUMAC Agro the humus content in soil and its pH increased (due to buffering effect) as well as contents of the available forms of all observed nutrients (P, K, Mg, B, Mn, Cu, Zn and Fe) in spite of higher sugar beet yield and thus higher nutrient uptake compared to the control treatment. The mentioned soil properties increase applied also when compared to the state in the beginning. The higher humus content may be caused by the increased yields (besides the conditioner humic acids input), due to higher formation of root mass, which remains in the soil after harvesting the crop. Conversely, higher content of available forms of solved nutrients in the soil usually correlates with their lower consumption and lower harvest. Higher nutrient uptake by higher yields and higher soil nutrients content at the same time is a desirable effect of soil conditioners that prevent leaching of mobile nutrients and increase the accessibility of nutrients from their unavailable forms in the soil. The mentioned desirable effect is not obvious in any soil and climatic conditions, so it is therefore necessary to quantify the effect of soil conditioners on the soil properties by laboratory analyses especially to prevent a decline in nutrients due to increased yields. The values of monitored soil parameters for the control variant compared to their initial state showed decrease with the exception of Mn and Fe contents. © 2015, Listy Cukrovarnicke a Reparske.

The general objectives of PROMISE are: PROMISE strives for multidimensional networking thus fostering integration The primary strategic objective of PROMISE is to improve and increase the integration, collaboration and knowledge transfer between the new member states, old member states (EU15) and candidate countries through a collaborative workplan of exchange of expertise and regional training and dissemination actions, to tackle common food safety threats. PROMISE strives for sustainability through involvement of risk communicators A further strategic objective is to integrate stakeholders like public health authorities and national food safety authorities from the old and new member countries in order to ensure the exploitation of research results into standardisation and harmonisation efforts. PROMISE will enhance the knowledge on pathogen transmission While legal imports are well monitored for contamination and alerts are registered through the Rapid Alert System for Food and Feed (RASFF; http://www.efet.gr/docs/rasff/report2008_en.pdf) notification systems, gates into the EU-27 could exist where food supply chains are not controllled. These uncontrolled imports present the risk that new strains of traditional pathogens will be transferred from third countries into the European Union. Analysing, assessing and interpreting this risk of introducing new strains of pathogens is one of the main objectives of PROMISE.

This paper describes the biological properties of wild hemp Cannabis ruderalis Janisch, an original weed species under Central-European climatic conditions of South and East Slovakia, with the potential of high economic importance especially concerning some localities of the country where sugar beet is grown. It also outlines the specifics for agronomical and herbicidal management of sugar beet stands against the weed, these procedures improve the herbicides efficiency based on 2–3 times repeated or divided application of mixed herbicides based on phenmedipham, desmedipham, ethofumesate and chloridazon until the hemp plants have 2–4 leaves, respectively their efficiency can be improved by further mixtures with triflusulfuron-methyl or metamitron, which is effective also when used on its own preemergently or postemergently. The paper also describes the sensitivity of wild hemp to many other herbicides commonly used in the protection of field crops stands cultivated in Slovakia as fore crop or after crop of sugar beet. © 2015, Listy Cukrovarnicke a Reparske.All Rights Reserved.
