RISK OF INFLUENCE AND MANIFESTATION OF DROUGHT IN THE REPUBLIC OF MOLDOVA
Get PDFNatural risks have been and are for agriculture the negative factor, which needs to be taken into account in the development of the agricultural sector. Due to the fact that the Republic of Moldova is located in a climatic zone with insufficient humidity, it is periodically subject to the influence of particularly strong droughts. Droughts in recent years confirm the insufficient level of adaptation of agriculture in the Republic of Moldova to drought conditions, which more and more frequently and with increased intensity, especially in recent years, affect the agricultural sector. This article provides a brief analysis of the general synoptic mechanism of drought genesis in the Republic of Moldova, types of drought, economic impact, probability of occurrence, drought register for the period of X-XXI centuries. The authors emphasize from the beginning the great variety of dangers that appeared in this territory, giving us concrete data and examples. Also, in this paper is described the fact that out of all the dangers appeared on the territory of the Republic of Moldova, as well as all over the world, drought prevails, caused by climate change. The completion of the drought registers by 2020 indicates a general trend of increasing the frequency of their production, due to the anthropogenic impact on the environment and regional and global climate change. Through this work, the author makes a modest contribution to the study of natural hazards in the Republic of Moldova, with a great destructive potential and which can cause extremely great damage to the economy and the national environment. From this perspective, it is necessary for agricultural entities to analyze the probability of damage and their assessment, because the specifics of their field of activity, are environments in which the risk of drought can manifest itself, mainly. Thus, it becomes necessary to develop urgent as well as long-term measures to reduce the risk of drought
THE CHARACTERISTICS OF SOME ANIMAL SPECIES FROM DOLJ COUNTY AND THE IMPORTANCE OF THEIR CAPITALIZATION
Get PDFDolj Forest District manages a surface of 59 800 ha public forest fund and 9 125 ha private property forest fund. Non-wood forest products represent an important part for all industries, as well as for the gastronomic and artisanal domains. In this context, the present paper presents the importance of capitalizing game species and the need for this sector`s development, by taking into account three species frequently found in this area. The crop goose (Anser fabalis) is a species with a high price for the raw product as well as for the derived products. Partridge (Perdix perdix) has a smaller harvesting period and distribution range and the largest quantities are found in forest units of Amaradia, Perişor and Filiaşi. Pickerel (Esox lucius) is a very popular species, with a high selling potential and an increased market request. These species belong to the 8 game species that were analyzed through the AHP interval based on 19 criteria
THE INFLUENCE OF FERTILIZER DOSES ON SOME INDICATORS OF STRAWBERRY FRUITS CULTIVATED AT POLOVRAGI, GORJ COUNTY
Get PDFStrawberry, a small fruit species, is highly valued for its rich fruit with a special nutritional and therapeutic value. In order to establish how the different doses of fertilizers influence the degree of assimilation of nutrients in strawberry plants and fruit quality, we performed a series of chemical and biochemical determinations on strawberries grown in Polovragi, Gorj County under the influence of the following fertilizer doses: 51-36-75, 102-72-150, 136-96-200, 54-70-75, 102-140-176, 153-210-240, 81-72-50, 162-142-100, 243-214-150 (NPK).The soil on which the experiment was placed is a skeletal cambic nigrosol. The Yara Mila Power complex fertilizer type 17-12-25 was used, supplemented with simple fertilizers with nitrogen, phosphorus and potassium to reach the appropriate dose
EFFECTS OF MICROGRANULATE STARTER FERTILIZERS ON GRAIN CORN
Get PDFOltenia, one of the most important agricultural regions of the country, is also one of the regions with extreme weather, which puts crop plants under stress.That is why it is important that the crop plants have all the necessary nutrients from sowing. Starter microgranulate is a fertilizer that does this.The use of a starter fertilizer for sowing corn is a wide spread practice in Europe. This type of fertilization shows good results for poor, sandy, acidic or basic soils, ensuring a good initial vigor and a better homogenity of the emergence.In corn, there is a close correlation between the development of the root system and the growth of the foliar apparatus. As phosphorus stimulates root growth, it turns out that the easily assimilable phosphorus present in the soil in the first part of the vegetation can positively influence the production.he abstract in English (max.10 lines) focusing on the results of the research
OBSERVATION OF THE ATTACK CAUSED BY THE LARVAE OF DIABROTICA VIRGIFERA VIRGIFERA, UNDER THE DIFERENT TILAGE IN CORN CROPS OF NEAMŢ COUNTY, UNDER CONDITIONS OF 2020
Get PDFIn the current context, of banning neonicotinoids triatments, tillage systems and crop rotation are vrey important rings in controlling larval attack. The samples was collected in the corn crop from Ghigoiesti stationary, Neamt County. .The period of observation, harvest samples was carried out between May and August 2020, by taking over biological material represented by corn roots, that have been brought into the laboratory for examination and processing the data obtained. From the collected biological material, the Diabrotica virgifera virgifera specimens that have been determined and centralized have been retained.  The material was harvested on the three variants represented by no tillage (V1), minimum tillage  (V2) and conventional tillage (V3). All three varians are planting in soil tratament with Force G 1.5.Folloing the collection of samples and after analises, during the period of observation, were had colected a number of 1239 specimens of larvae of Diabrotica virgifera virgifera. And  after centralization at variant 1 we totaled 457 specimens, at variant 2 we totaled 418 secimens and at variant 3 we totaled 364 specimens
INFLUENCE OF CONTAINER VOLUME ON THE PLANTS QUALITY IN THE PRODUCTION OF SOME BEGONIA L. SPECIES
Get PDFThe plant size, growth rate and the degree of branching represent important criteria for determining the stage of commercial plant. This paper aimed to study the behaviour of plants belonging to the species Begonia masoniana and Begonia rex depending on the volume of substrate, in order to obtain plants for sale. The plant material, obtained from leaf cuttings, was planted in a mixture of peat and perlite (2:1), in pots of different sizes: 8 cm (0,32 l), 10 cm (0,4 l), 12 cm (0,7 l). The observations and determinations were focused on: the average height of the plant, the average diameter of the plant, the average length and width of the leaf, the average number of leaves. In order to obtain in a short period of time plants with rich shrubs for sale, it is recommended in the case of the Begonia masoniana species to use pots with a diameter of 8 cm, respectively a small volume of substrate. The main morphological characteristics of Begonia rex ‘Inca Fire`, express the best performance of plants in the larger volume container (12 cm diameter)
