STUDIES ON THE MAIN CHEMICAL COMPOUNDS AND QUALITY INDICES OF RED WINES FROM THE MAIN VINEYARDS IN OLTENIA

Recently, worldwide, there has been a decrease in wine consumption, as the consumer has become much more attentive to the quality of this food, refusing products that do not meet certain standards. At the same time, the new world wine regions specialize in quality production, coming on the market with a varied offer and at a convenient price. The fame of the particularly pleasant characteristics of Romanian wines is given not only by the extremely high value of several local varieties, which have given fame to some wine centers: Fetească alba by Alba Iulia, Grasa by Cotnari, Tămâioasă by Drăgăşani, or by Pietroasele, Busuioacă by Bohotin, Fetească neagră de Nicoreşti, Negru de Dragasani, etc., but also the fact that the most famous foreign varieties, which made famous certain regions and countries (Traminer, Sauvignon, Cabernet Sauvignon, Merlot, Pinot), cultivated in Romania wines that have often equaled or surpassed, by their "generosity" and finesse, those of the countries of origin. For wine and especially red wine, it is important to establish its typicality and authenticity due to its impact on the large mass of knowledgeable consumers who value quality and safety.Â

VERIFICATION OF THE ROOTSTOCK ON THE INFLUENCE ON THE GROWTH AND FRUITING PROCESS TO SOME VARIETIES OF APRICOTS

In order to achieve a balance between growth and fruiting, we need to know the peculiarities of growing and fruiting apricot varieties in different areas of the country, in different climatic conditions and under the influence of different rootstocks. From the analysis of the root system we conclude that varieties with a more developed root system, such as NJA 42 have a higher vigor, and varieties with a more superficial root system, give the trees a lower vigor. Varieties with thicker roots in greater numbers, help the absorption of nutrients from the soil, helping the normal development of trees. The study of the peculiarities of tree growth, can specify the way of cutting the respective species, the optimal choice of the crown shape as well as the way of forming the crown. According to the obtained data, we specify that the first order branches represent 30.6% of the total length of the skeleton, and the second order branches represent 69.2%. In the southern part of the country, the researched apricot varieties have demonstrated their favorability for this area, through superior quantity and quality

THE INFLUENCE OF POTENTILLA REPTANS EXTRACTS ON THE PHYSIOLOGY OF AGROPYRON REPENS L. PLANTS

During the experiments, the influence of the aqueous extracts obtained from the leaves of Potentilla reptans on the physiology of Agropyron repens was studied.Agropyron repens is a plant of spontaneous flora of Romania, growing on cultivated and uncultivated soils and is one of the most harmful plants in agriculture.In areas where Potentilla reptans grows, couch grass growth is inhibited; this demonstrates that this plant can have an allelopatic action on the couch grass. During these experiments, aqueous extracts from the leaves of Potentilla reptans were used in concentrations of 5 g / l, 10 g / l, 15 g / l and 20 g / l. These extracts were used in order to water the Agropyron repens plants .The experiments focused on the intensity of leaf photosynthesis, leaf respiration intensity, transpiration intensity, leaf water content and chlorophyll content.In the variant with a concentration of 5 g / l, photosynthesis had much lower values, and at 20 g / l the process was reduced by about 50%.Regarding the respiration process, there was an increase, but only at high concentrations of the extracts (15 and 20 g / l). At low concentrations, the differences from the control were undetectable.In the control variant, the intensity of leaf transpiration had the lowest value. In the other variants, it has been found to intensify the transpiration process in proportion to the increase in the concentration of the extracts

ASSESSEMENT OF THERMAL REGIME IN OLTENIA USING TEMPERATURE-BASED CLIMATE INDICATORS RELEVANT FOR AGRICULTURE SECTOR

We present a quantitative evaluation of current climate (1981-2010) thermal conditions relevant for the agriculture sector by using seven agrometeorological climate indices computed based on the ROCADA dataset. The temperature-related indicators characterize the cold period of the year (i.e. sums of minimum air temperatures ≤â€10°C recorded in Decemberâ€February interval), the bounding seasons (e.g. zero crossing days), heating degree days) or are more specifically oriented for the growing season (i.e. Growing degree days; growing season mean temperature during Aprilâ€October/ May-September interval; Winkler index). The indices are computed for the entire Romanian territory, highlighting the thermal climatic features of the Oltenia region

RESEARCH ON DEVELOPING A MULTIFUNCTIONAL EQUIPMENT FOR HARVESTING MEDICINAL AND AROMATIC PLANTS FOR USE ON SMALL AREAS

Cultivation technologies of medicinal and aromatic plants characterize harvesting operations as being difficult, because they have a significant effect on the plant material quality. Therefore, regardless the harvesting method used (either manual or mechanical), the intervention on the useful part of the plant have to be kept to minimum. Mechanized harvesting is usually an important prior factor for achieving profitable productions, and this aspect is also valid for medicinal and aromatic plants. In order to improve and adapt the cultivation technologies to the current Romanian requirements, and analyzing previous practical experiences, INMA Bucharest has achieved a multifunctional equipment for harvesting annual and perennial medicinal and aromatic plants, with applicability on small land surfaces. The paper presents the experimental model of an innovative equipment and the expected advantages, compared to the previously made harvesting equipment

COMPARATIVE STUDY OF A CERTAIN SORGHUM HYBRIDS CULTIVATED FOR FEED IN OLTENIA CENTRAL AREA

Setting the feed crops assortment is one of the actual problems. The main concern represents the setting of the species and varieties with maximum production potential in the existent ecopedological conditions (Cotigă, C.2012). In this regard, are preferred the species of which technology are fully mechanized, among which is also the feed sorghum culture. If we refer to sorghum culture to provide feed base, among hybrids that we consider for research is remarked ES ALIZE and ES FOEHN, which can provide a production of 7-8 t/ha s.u. beans and strains + leaves of 8-9 t/ha s.u

THE ECOLOGICAL RECONSTRUCTION THROUGH AFFORESTATION WORKS ON THE RUNCURELUL DUMP HAVING THE AREA OF 27 HA

In recent decades, surface mining operations, especially in the mining basin of Oltenia, have developed a lot and as a result there have been large areas with degraded land and tailings dumps whose ecological reconstruction has been and is a topical issue.The Runcurelu Dump is located within the Jilţ Quarry, the territory of commune Mătăsari, more precisely in the Runcurelu meadow and is free of technological tasks. The spontaneous vegetation settled quite well, especially on the first plateau. Because the piled material was deposited in a completely random way, the surface of the perimeter is largely uneven, especially on the two slopes that border the plateaus. On the slope the slope is large and complex, ranging between 25-35% and over.From a geological point of view, the studied perimeter is very complex, belonging to both the Pliocene (Levantine) and the beginning of the Quaternary and Dacian (sands).Lithologically, it is represented by various inhomogeneously mixed geological materials. Following the coal mining process, respectively the dump process, the geological deposits of a great diversity were brought up to date and mixed very heterogeneously.The diversity of dumped materials is observed both chemically and physically. In this dump are alternately deposited all sorts of materials, from clays, marls, to sands with smaller or larger coal fragments

STUDIES AND RESEARCHES ON THE PREPARATION OF THE GERMINATION BED WITH HEAVY DISC HARROWS

Agriculture has been around since ancient times and continues to be today a vital area of human activity. It remains the only source of food, an important supplier of raw materials for industry and also a significant market for its production. Agricultural ecosystems as an integrated organic complex of natural, economic and social factors, require the rational, scientific intervention of the farmer, leading to raising its productivity, its protection and profitability, based on superior parameters of contemporary technology, making full use of market economy mechanisms.The area occupied in our country by the soils with crops that are established in autumn is about 37% of the total agricultural area. The mechanization technology which includes tillage by removing the stubble and/or preparing the germinated bed on unplowed land, on which the autumn crops are established, it can be applied at a qualitative level corresponding to the agropedological requirements, at a low cost price and with low energy consumption, by using disc harrows

ANALYSIS OF THE STAGES NECESSARY FOR THE CONSTRUCTION OF AN OBJECTIVE TAKEN OVER IN CONCESSION, FROM A TOPO-CADASTRAL POINT OF VIEW

Within the present work, a study was carried out regarding the concession of a building belonging to the Municipality of Cluj-Napoca, in order to dismantle it resulting in 32 plots and the access road to them, in order to authorize the construction works of 32 dwellings for young people. The notion of drawing represents the application on the field of the topographical elements known or extracted by calculation from the construction projects, elements that define a projected construction to be transposed or executed in the field. The field application of construction projects is aimed at ensuring compliance with the design and size of constructions and their components, as well as their absolute position, in a coordinate system. From the succession of constructive stages necessary for the construction of an objective, the materialization on the ground of the basic, main, and secondary axes of the construction and the materialization of the ±0.00 m elevation are detached. The law provides that the execution of construction works is allowed only on the basis of a building permit that is issued following a project called a Topographic Plan for obtaining the building permit
