STUDY REGARDING THE BEHAVIOR OF SOME VARIETIES OF WHEAT, IN ECOPEDOLOGICAL CONDITIONS, FROM THE SOUTH-WEST AREA OF DOLJ COUNTY
Get PDFThe research aims at the comparative study of some varieties of autumn wheat in conventional cultivation system, in the conditions of the eutricpsamosol, from Poiana Mare, on an area of 300 ha cultivated with wheat, for a better knowledge of them, in order to the recommendation to cultivate in the area, the varieties that can express to the maximum, the productive and qualitative potential.For two years (2019 - 2020), within S.C. Primagrimar SRL Poiana Mare, Dolj were grown wheat varieties: MIRANDA, OTILIA - Romanian varieties and AVENUE, SORRIAL - French varieties. Regarding the obtained production, the Miranda variety registered the average value of 7800 kg / ha, and the Sorrial and Avenue varieties obtained an average production of 8050-8150 kg / ha.The high production of these French varieties is argued by the fact that they belong to the Premium group, very productive, very drought tolerant and with high ecological plasticity, with good resistance to wintering, falling, diseases and high twinning capacity, receptive to fertilizer doses, superior in terms of quality.The biological potential is very high reaching 11.000 kg / ha. Given the very high rainfall in June, when the plants reached physiological maturity, in both years of research, it was observed that foreign varieties lose their baking qualities very quickly, due to rains that "wash" gluten and reduce their hectoliter mass, which is not the case with Romanian varieties. Avenue, being extra early, was the most affected during the research period
THEORETICAL CONSIDERATIONS ON CHOOSING THE VIBRATION METHOD AND SPEED OF ELECTROVIBRATOR FOR MILLING MACHINES
Get PDFThe simplification of the kinematic chain for the equipment in the milling industry has been an ongoing concern for the manufacturers in this field. Thus, the aim was to replace the eccentric drive with electric vibrators. The use of electric vibrators to drive the equipment used in the technological processes of cleaning leads to a number of advantages compared to eccentric drive: simplifying the kinematic chain, intensifying the separation process, reducing stress on the foundation. The use of electric vibrators in grain cleaning machines is increasingly common worldwide in companies with a tradition in the field. Therefore, the choice of the vibration method and the required number of vibrations per minute capable of achieving the best efficiency is an important issue that will be addressed in this paper
STUDIES REGARDING THE EVOLUTION OF CLIMATE INDICES IN THE MATURATION PROCESS OF GRAPES IN DRĂGĂŞANI VINEYARD
Get PDFÂ Â Â Â Â The Drăgăşani vineyard has a favorable climate to ensure the ripening of the grapes as well as the strings necessary for next year's fruit. Being located in the Getic plateau, the vineyard has a temperate Mediterranean climate with oceanic influence. The study was carried out at the Research and Development Station for viticulture and vinification Drăgăşani on Olt Hill in 2019. The objective of the study was to monitor the influence of the climatic profile on the physico-chemical parameters in the grape ripening process. For the evaluation of the area, the active and useful balance, the real insolation, the sum of precipitations, the heliothermal index, hydrothermal coefficient, the bioclimatic index of the vine and the oenoclimatic aptitude index during the vegetation and development period were calculated
THE IMPACT OF USING EQUIPMENT WITH DIGITAL CONTROL ON MODERN AGRICULTURE 4.0 - REVIEW
Get PDFLately, the widespread use and continuous improvement of machine tools has had a significant impact on productivity in the manufacturing industry since the Industrial Revolution. At the beginning of the new era of industrialization, the need to advance machine tools to a new level, which corresponds to the Industry 4.0 concept, must be recognized and addressed. Like the various stages of industrialization, machine tools have also gone through various stages of technological advances, namely Machine Tool 1.0, Machine Tool 2.0 and Machine Tool 3.0. Industry 4.0 advocates for a new generation of machines - Machine Tool 4.0. This paper describes some of the key and desired features of the implementation of intelligent machines such as numerically controlled lathes and milling machine tool centers integrated vertically and horizontally in order to achieve a modern, intelligent, autonomous and safer agriculture
AGRICULTURE 4.0 - THE USE OF SMART TECHNOLOGIES FOR HIGHPERFORMANCE AGRICULTURE
Get PDFGiven that the labor market in Romania has an acute shortage of labor (about 1 million people), in agriculture this lack is felt even more acutely because the population in the villages is declining and aging, thus it is increasingly difficult for Romanian farmers to find labor, let alone skilled labor. One solution can be the digitization of agriculture, ie the introduction of the latest management concepts, sensors, automation, robots, etc. in the modernization of work processes in agriculture, thus reducing the need for labor, while increasing productivity and efficiency in agriculture
A STUDY ON THE SELECTIVITY AND EFFICIENCY OF A GROUP OF HERBICIDES IN "DUNAVIYA" WHEAT VARIETY
Get PDFIn the experimental field of the Institute of Agriculture and Seed Science "Obraztsov Chiflik", Ruse, in 2017 - 2018, a study was conducted to determine the reaction of "Dunaviya" wheat variety, treated with herbicides for foliar fertilization at optimal and double doses - metasurfuron - methyl, fenoxaprop-P-ethyl, 2.4 amine salt. They did not have negative effects on the plants. Regarding destroyed weeds, all the three tested vegetation herbicides (metasurfuron - methyl, fenoxaprop-P-ethyl and 2.4 amine salt), applied at optimal and increased doses, showed high herbicidal efficiency against annual cereal and deciduous weeds. The use of metasurfuron - methyl, fenoxaprop-P-ethyl and 2.4 amine salt herbicides led to higher grain yield, compared to the untreated control
RESEARCHES ON THE DEVELOPMENT OF AN EXPERIMENTAL MODEL OF FISH POND FOR INTENSIVE FISH FARMING IN POLYCULTURE SYSTEM
Get PDFIn Romania, the fisheries and aquaculture sectors face several challenges. These mainly involve increasing competitiveness for the production and processing sectors. Polyculture is the breeding of several species of fish in the same space (pond, lakes, etc.). It has advantages: better capitalization of trophic potential, diversified assortment for consumers, increased production with the same human and financial effort and disadvantages: competition between species, the need for additional labour in harvest fishing, additional warehouses for parking fish. Polyculture is recommended in lakes, ponds and some ponds for extensive, semi-intensive and sometimes intensive production
RESEARCH ON THE LEVEL OF NITROGEN FERTILIZATION ON THE PRODUCTIVITY OF MIXTURES OF PERENNIAL SPECIES SPECIFIC TO THE ECOPEDOLOGICAL AREA OF EXPERIMENTATION S.C.D.A. ŞIMNIC-CRAIOVA
Get PDFThe use of fertilizers is an important measure to increase production and improve the quality of feed obtained from temporary grasslands.If we refer to the mixtures of grasses and perennial fodder legumes studied and to the doses of nitrogen fertilization applied, for a first stage the mixture is highlighted: Medicago sativa 40%. As a level of nitrogen fertilization, the dose of N120 with fractional application for each harvest cycle and which can give over 6.7 t / ha s.u.Â
CULTIVATION TECHNOLOGY AND BENEFITS OF FENUGREEK
Get PDFFenugreek (Trigonella foenum-graecum L.) is a plant native to the Mediterranean region. The name of the species means "Greek hay" because in the past it was used as a forage plant, another use being that of spice or medicinal plant throughout the world. Fenugreek is one of the oldest medicinal plants, having positive effects on antidiabetic, anticarcinogen, hypocholesterolemic, antioxidant and immunological activities, can also be used as a green fertilizer, enriching the soil with nutrients. This paper aims to describe the technology of cultivating fenugreek, but also to highlight its main benefits
