THE EFFECTS OF THE CORONAVIRUS PANDEMIC ON THE DEVELOPMENT OF HUMAN RESOURCES IN THE SOUTH WEST OLTENIA REGION
Get PDFThe coronavirus pandemic has strongly affected every sector of the economy. Every organization, every employee within the organizations, had to adapt to the situation and adopt new ways of doing the work at the workplace. Of course, the development of human resources within organizations has acquired another dimension. The focus was on trying to maintain jobs and developing human resources through the means available to the organization in this pandemic context. Telework was introduced and human resource financing activities through European projects were reduced. The implementation of projects with non-reimbursable European funding was quite difficult during the state of emergency and then in the state of alert, which led to a decrease in continuous professional training activity and, implicitly, to the development of human resources in the South-West Oltenia region
DATA ON THE PRESENCE OF INVASIVE AND POTENTIALLY INVASIVE ALOGEN PLANTS IN OLT COUNTY (ROMANIA)
Get PDFThe research carried out in Olt County regarding invasive and potentially invasive alogen plant species is a necessary step in order to complete the information on their distribution at the national level. The data obtained will be able to be used for a careful monitoring of these plants and the adoption of the necessary management measures regarding the eradication or prevention of their introduction and spread.
In this sense, an inventory of invasive and potentially invasive plant species identified on the territory of Olt county is presented, with information on the geographical origin, life form, biological form, an assessment of the degree of invasiveness, chorological data, habitat, as well as aspects related to the impact they exert on native vegetation, human health or the economy.
The preliminary analysis of the list of invasive and potentially invasive alogen plants identified in Olt County highlights, in particular, the presence of some species of concern for the European Union (such as Ailanthus altissima, Asclepias syriaca and Elodea nuttallii). Besides these, the most widespread invasive species found in Olt county are Ambrosia artemisiifolia, Robinia pseudoacacia, Morus alba, Amorpha fruticosa, Acer negundo, Amaranthus retroflexus, Erigeron annuus, E. canadensis, Lycium barbarum, Sorghum halepense, Xanthium orientale subsp.italicum. It is well known that the impact of invasive species on the environment, the economy and in some situations even on human health is major and that is why these organisms must be subject to an extensive and continuous monitoring process. Also, in order to control the introduction and spread of invasive and potentially invasive species, a series of appropriate management measures are required
FOLIAR FERTILIZATION - AN INTEGRAL PART OF COMPLEX AND INTEGRATED FERTILIZATIONS – A REVIEW
Get PDFIn the context of demographic increase and climate change, the issue of ensuring food security is becoming increasingly important, which is why the use of chemical fertilizers in agriculture is the main means of increasing the quantity and quality of agricultural production. Alongside basic mineral (root) fertilization, which is indispensable, foliar fertilization is a measure of increase both in terms of yields and quality. Foliar fertilizers provide a surplus of fertilizing elements, especially secondary macroelements and microelements, which allows plants to thrive under optimal conditions and to resist stress factors. Foliar fertilization has become a widespread management tool in directing the nutrition of crop plants, and is often a complementary part of fertilization systems or even seen as an alternative to root fertilization. When applied correctly, foliar fertilization has an interesting potential to manipulate the yield and quality of agricultural production, with low environmental impact and relatively low costs. This review aims to highlight the importance of foliar fertilization for agricultural crops, based on experimental results from the literature, using the platforms Google Scholar and Web of Science for documentation
STUDIES REGARDING THE CURRENT SITUATION OF INVESTMENTS MADE WITH EU PUBLIC FUNDS IN MEAT AND MILK PROCESSING UNITS, IN THE SOUTH-WEST OLTENIA REGION
Get PDFThe most important areas of the food industry are meat and milk processing and have a particular impact on increasing the competitiveness of the national economy, but also on ensuring the food security of the population.Through the study, I proposed to provide an overview of the growth and development of meat and milk processing capacities by using the non-reimbursable funds offered by the European Union through the National Rural Development Program, to make an analysis of the current situation on these investments through these funds. In the food industry, in meat and milk processing units, at national level, between 2015 and 2019, 130 projects were financed, with an eligible value of €228,470 thousand (public value €114,937 thousand). At the level of the South - West Oltenia Region, 12 projects were selected where their eligible value was €32,164 thousand (public value €15,309 thousand)
RESEARCH ON ADDITIONAL FERTILIZATION IN EARLY POTATO CROP ON SAND SOIL
Get PDFThe early potato is one of the most profitable crops. It must be cultivated only in those areas where the environmental factors are favorable for achieving large productions, and the southern area of Oltenia meets the necessary conditions required by the plant's biology. The researches followed the efficiency of the foliar fertilization as well as the behavior of the early potato plants regarding the realized production, depending on the administered dose. The use of foliar fertilizers on early potato has led to increased yields in all variants. By applying the ATON ZN product, the production of tubers achieved in 2021, of 36266 Kg/ha, was superior to the untreated control by 11100 Kg/ha, which means an increase of 44.1%. By applying the SEACTIV SILVER product, the production of tubers achieved in 2021, of 32166 Kg/ha, was superior to the untreated control by 7000 Kg/ha, which means an increase of 27.8%. The increase in production was achieved due to the increase in the average weight of the tubers from the variant treated with SEACTIV SILVER, which was statistically assured as distinctly significant positive
EXPERIMENTAL RESULTS REGARDING MINERAL FERTILIZATION AND FORMS OF NITROGEN, APPLIED TO TEMPORARY MEADOWS IN THE CENTRAL AREA OF OLTENIA
Get PDFThe use of fertilizers is an important measure to increase and improve the quality of the fodder obtained from the temporary meadows (Barbulescu C. and colab. 1987). From the research carried out by us, it resulted that mineral fertilizers, especially nitrogen-based, contribute not only to the increase of the biomass harvest, respectively its quality, but especially to the improvement of the structure of the species used to make up the mixture of herbs. In this sense, for the area where the research was carried out, the use of the dose of P70 combined with the application of an annual dose of N120 in the form of nitrolimestone contributed to obtaining a production of about 9,7 t/ha s.u. and with the most favorable economic effects
PERFORMANCE OF SOME ROMANIAN WINTER WHEAT CULTIVARS UNDER ORGANIC AGRICULTURE CONDITIONS II. BREAD MAKING QUALITY INDICES
Get PDFIn order to explore genetic possibilities for producing wheat suitable to bread-making industry requirements, we tested 16 Romanian winter wheat cultivars in yield tests organized in South Romania at Fundulea, during 2019-2022. Grain protein concentration was generally low, only line FDL Amurg fulfilling on average, but not every year, the requirements for Grade 1 (in Romania, the requirements for organic wheat are the same as for conventional wheat, although the protein content is generally lower under organic conditions). Most tested cultivars belonged to Grade 3, with average grain protein content below 11%. A significant part of grain protein variation was associated with grain yield variation, but two genotypes (FDL Amurg and Voinic) showed positive deviations from the regression yield – grain protein content. Zeleny sedimentation and the alveograph W index were strongly correlated with grain protein percentage, suggesting that, in order to produce high quality wheat under organic agriculture, improving grain protein concentration, genetically or by crop management, is most important
PRELIMINARY CHROMATOGRAPHICRESEARCH ON SOME SALVIA SPP. (LAMIACEAE)
Get PDFSalvia genus, representative for the Lamiaceae family as it comprises approximately one thousand different species, is considered for a wide plethora of therapeutic actions, such as antioxidant, anti-inflammatory, hepatoprotective, antitumoral and antidiabetic activity. The paper presents the preliminary chromatographic investigations of the polyphenols in the aerial parts of some Salvia spp. Using high-performance thin-layer chromatography (HPTLC) coupled with photodensitometry, caffeic acid was identified and quantified in the 20% methanolic extracts of Salviaeherba, in descending order, as follows: S. nemorosa (3.096%) > S. verticillata (3.041%) > S. sclarea (2.663%) > S. glutinosa (1.962%) > S. aethiopis (0.926%)
A SENSITIVE SANDY SOIL UNDER PASTURE AS MICROORGANISM HABITAT PROVIDER
Get PDFThe sandy soils are sensitive ecosystems, being in a precarious equilibrium with the pedolandscape conditions, any changes could bring drastically modifications into the soil environment. The researches had been performed in Suceava Tableland, in Stephan the Great area, on a Luvosol albic-psamic, lamelar. The researches in the paper focused on the upper part of the argic horizon, on Bt1 sub-horizon characteristics at macro- and microscopic scale. In this respect, at the macro-morphological level, the Bt1 sub-horizon is composed of a sequence of thick lamellae (3–5 cm) separated by the inter-lamellar spaces. The granulometric analysis showed that the lamellae had a medium loamy texture, while the inter-lamellar spaces had coarse granulometric composition. At micromorphological level, the image emphasized, in the lamellae, the presence of the clayey±Fe±humiccoating the mineral grains and clogging part of the inter-granular spaces. The results of the microbiological investigation showed a concentration of the microorganisms into the lamellae, while in the inter-lamellar spaces, their development has been scarce. The total counts of bacteria and fungi registered low number (16.81 x 106 viable cells x g-1d.s. and 1.026 x 103cfus x g-1d.s., respectively). Despite of these results, the data of the global indicator of the soil microbiological activity, the soil respiration respectively, attend high level of activity (31.357 mg CO2 x g-1d.s.). The researches pointed out that the sandy soil is a very sensitive environment for the soil life, but the presence of the clayey±Fe lamellae proved to be a hospitable habitat.
 
THE POTENTIAL MEASURES FOR REDUCINGTHE DROUGHT EFFECTS IN DANUBE FLOODPLAIN,ON SADOVA-CORABIA SECTOR
Get PDFChanges occurring at the global and regional level as a result of climate change generate a series of problems with a significant negative impact on local communities, on aquatic and terrestrial ecosystems, on the local economy and on the entire society. The medium and long-term effects of these phenomena are difficult to quantify and evaluate, but scientific research can bring innovative, realistic and pragmatic solutions, with the aim of reducing the main negative effects in an important area affected by the extreme events, such as drought, aridization, desertification, flash floods, all in the context of the climate change. The present paper is focused on the aspects related to the water management in drought affected areas of the Danube Valley, taking in to account a study case placed in the Sadova-Corabia sector, a riverside sector of the Danube River, which includ an important part of Dăbuleni area, considered the "pole of desertification" in Oltenia region and even in Romania. As a novelty element, the paperwork brings to attention a holistic approach regarding the implementation of the measures that respond equally to the requirements related to water management both the requirements of the Water Framework Directive 2000/60/EEC, but also to the Flood Directive 2007/60/EEC
