11.g9.1. GENERAL PROBLEMS OF AGRICULTURE

11.g9.1.1. Globalization and problems of specialization of Georgia’s agriculture. /T. Kavtaradze, M. Kavtaradze/. Ekonomisti (Economist). – 2012. - #1. – pp. 51-58. – geo.; abs. eng.

The work studies the problems of specialization of agriculture under globalization, reviews the stages of specialization development; defines an indicator of specialization at the national and regional levels. According to the indicator, the current level of specialization is comparatively lower that the one existing before the reform, the cause of which should be sought  in paying major attention lately to the production of cereal, potato and livestock products, or staple foods. Appropriate measures aimed at raising the level of agricultural specialization ad concentration are set out.

According to Georgian legislation, land which is not used for agricultural purpose is considered to be a non-agricultural land. Origination of the right of ownership on a non-agricultural land in Georgia was preceded by privatization of buildings and structures. After adoption of the Civil Code of Georgia (November 25, 1997), which united a plot of land and a building thereon in the concept of a single immovable property and excluded recognition of the plot of land and the building situated on it as two objects of different rights (Civil Code, Article 150), the issue of transfer of non-agricultural plots of land into private ownership became essential. Following are the forms of privatization of State owned immovable property (non-agricultural land): a) auction; b) direct Sale and c) direct sale on the basis of a competitive selection. It must be noted that state owned land is not fully registered in Georgia. In case of privatization of land selected by the interested person the land is surveyed and registered in the Public Register in the name of the State or the local government and after that the privatization procedure of the real estate begins.

The paper deals with the issues related to the accounting by an enterprise of the biological transformation of living animals or plants (biological assets) for sale into agricultural produce or into additional biological assets. Basically, fair value can be measured reliably for a biological asset only on initial recognition for such market-determined prices. However, during the future period of exploitation, the fair values are not available and consequently suggested alternative estimates. In such a case, IAS 41 requires an enterprise to measure that biological asset at its cost less than any accumulated depreciation and any accumulated impairment losses. Once the fair value of such a biological asset becomes reliably measurable, an enterprise should measure it at its fair value less estimated point-of-sale costs. Ref.4

The rapprochement of economic policies between Georgia and the Åuãîðåàï Union, which represents àï objective of the second (economic) platform of ÅàÐ, is impossible without consideration of the EU's agricultural policy and development of à corresponding policy for Georgia. At present, Georgia lacks such à policy. The realistic process ongoing in agriculture, in general, and in the agricultural innovation system, in particular, differs radically from the European îïå. Notwithstanding obvious achievements, they, in the EU, believe that the uniform agricultural policy needs to be changed, mainly in the direction of innovation and sustainability, so that it could meet new challenges, such as: the sustainable development under conditions of climate change; the development of organic agriculture; the escalating prices on food products; the necessity of biofuel production, etc. The next decade will see àï increase in the assistance to farmers in the direction of innovation activities, such as the compliance with the environmental, food safety and security, and other standards. The innovation activities in rural development (not agricultural) will be enhanced. Such à scenario increases the importance of all components of àï innovation system: education, research, the accumulation and transfer into production of commercialized knowledge. The components of the innovation systems available in Georgia are degrading by all parameters (research institutions, demonstration farms), whereas under à market economy conditions new necessary components (e.g. agricultural advisory service) are not created. This trend runs counter to the Åuãîðåàï and world practice, and recommendations of international organizations. Because of the above, the possibilities of not only the Åuãîðåàï integration but also of the revival of agriculture are called into question. In EU, at the national and regional level, there are many useful for Georgia models. The ÅàÐ can be successfully used for studying them. Fig. 4, Tab. 2.

The article presents information on the state of the agricultural complex within the reclaimed area of Kolkheti Lowland. One-sided specialization of subtropical crops production failed to bring forth harmonious development of agricultural. Taking into account demand for wheat and the resultant increase in prices, also in order to provide population with staple food products a structural reform of agricultural lands in the central part of the Lowland is proposed. Increase of lands under cereals and forage crops at the expense of perennials requires the use of drainage techniques designated for one-year plants, given heavy permeable soils in this part of Kolkheti, such as the arrangement of a “bed” or combined drainage against the background of trenching.

The article proves the necessity of diversification of the farms in East European and Central Asian countries, as well as in Georgia. The new trends and possibilities currently taking place in the course of diversification are analyzed and the main reasons of diversification identified. Based on the analysis of the rates of incomes and poverty of the farmers in the East European and Central Asian countries, including Georgia, à conclusion is made that overcoming the poverty and increasing the welfare of the rural population depend directly upon diversification of the farms. The article proposes the ways of diversification both within and out of the borders of rural areas. According to the bibliographic studies and experts' assessments, diversification of farms is considered as à real tool for increasing àï added value in the agrarian sector. The article provides the rates of use of the workforce in the farms by regions, with and without diversification thereof. À level of expansion of the farms is assessed by the harvest diversification Index, while the latter is analyzed in reviews of the Eastern European and Central Asian countries and Georgia. The Article reviews à correlation between the harvest diversification Index (DI) and the added value on one hectare per înå farmer, in the agricultural sphere. On the basis of analysis of diversification of the farms, the existing problems are identified and the recommendations for their settlement are provided. Fig. 9.

Liberal trade policy and membership agreement with the World Trade Organization created favorable conditions for imports of subsidized products produced by using high technologies, which in its turn entailed disappearance of Georgian products from the market. Because of the above, the problem of raising competitiveness of Georgian products became very critical. Under the currents conditions, the problem cannot be solved without a serous support from the state.

11.g9.2.18. The problems of agriculture in Georgia. /M. Kutelia/. The New Economist. – 2012. - # 4. – pp. 62-66. – geo.; abs.: geo., eng.

Development of agriculture is of vital importance for Georgian economy. Nowadays it faces numerous problems and challenges; there are many things that must be improved. 46.8% of Georgian population lives in rural areas, but it produces only 9.3% of GDP. There are some main reasons causing this, such as lack of motivation to expand production, high interest rates, and limited access to credits, outdated technology, and insufficient knowledge of new production methods. The greatest problem is that agricultural lands are divided into many small parcels. It is important to develop agricultural insurance and make it affordable for small farmers. According to most experts, Georgia has a significant agricultural potential that needs to be better utilized. Growth in agriculture would also have a very positive social impact. Further development of the sector is thus critical in terms of the country’s security and stability.

The European market is extremely important to Georgia, as the one third of its foreign relations is related to the European Union. Despite the fact that Georgia benefits from the EU’s Generalized System of Preferences (GSP), the structure of export has not changed significantly. Apparently the non-tariff barriers play immensely more important role. It is crucial that the government not only formulates the strategies but also translates it into reality and makes a step toward European integration. It mainly concerns the institutional reforms which are to provide removal of all the non-tariff barriers to the entry to European market for Georgia. The process of standardization, the issue of technical requirements and harmonization of customs legislation are of great importance.

In Georgian agriculture the area of crops and plants, cattle, all kind of agriculture products and food security indicators are sharply reduced. Uncultivated area makes over 55-60% of arable land. This is caused by price increase of material resources necessary for reproduction, such as fertilizers, chemicals, agricultural machinery and fuel. Many countries return total (Sweden) or partial (U.S., Germany, etc.) price of fuel purchase to the farmers who are involved in government programs. Subsidies by indirect taxes such as excise duty and value added tax for purchased diesel fuel is most acceptable for Georgia. Hence, a transparent mechanism should be worked out and relevant law should be passed by the Parliament.

11.g9.2.21. Private property as a determinant of economic freedom. /R. Gerliani/. The New Economist. – 2013. - # 1. – pp. 35-43. – geo.; abs.: geo., eng.

Private property is a major issue/element of the world economy as well as the economic policies of different countries. Private property is the basis for the creation of a free market economy. Economic history of the development of the world economy has experienced many forms of properties. However, for the most part, only private property reinforces the freedom and economic freedom. Both, economic freedom and private property issues are particularly interesting and relevant to the post-socialist space, including Georgia, because in the process of changes in political and economic structures followed by the transformation of state property into private one. Therefore, the need to protect private property, the dynamic nature of its in calculating the relevant indicators of the economic freedom study by international organizations. In conclusion, the overall situation of private property of a country’s assets affects key indicators of economic freedom, and overall economic growth. Ignoring private property is a situation in which the free choice and the condition for a free market are restricted, and without them economic freedom is considerably lower. In summary, private property and economic freedom are closely related to each other and are mutually complementary.

Rural and agro tourism are increasingly developing in industrialized countries. The criteria of selection of suitable accommodations are an important part of this process. The authors have built a classifier for rural and agro tourism accommodation points. The criteria involve 3 main components, each being defined by several parameters: a) the area ajoining the rural and farm house (parameters: landscape, distance from a populated point, sight-seeing places, etc.); b) technical conditions and facilities of rural and farm houses (parameters: repair, electric power supply, heating, air-conditioning, water supply, bathroom, toilet, furniture, kitchen, parking, greenery, etc.); c) possibilities of additional services (parameters: additional meals, emergency, Internet, child care, participation in agricultural work, additional tours, etc.) Evaluation of each component is accomplished by grading of each parameter and by subsequent calculation of percentage with respect to the maximal grade of this component.

Notwithstanding remarkable achievements, it is considered in the European Union that the common agricultural policy needs to be changed, mainly in the direction of innovation and sustainability because it is ïî longer possible to retain the "hothouse" conditions for farmers through subsidies, îï the one hand, and there is à need to respond to new challenges, îï the other hand. These àãå: sustainable development under global warming and climate change; development of organic farming; growth of prices îï food; the necessity of bio-fuel production, etc. In the next decade, assistance to farmers in the direction of innovation activities will increase; these include: compliance with the environmental, food safety and other standards. Ruãal development (non-agricultural) innovation activities will be enhanced. Such à scenario is to enhance all the innovation system components - the significance of education, research, accumulation and putting into practice of the commercialized knowledge.

This research studies recent conditions of farm loan and farm insuãance in Georgia and develops general recommendations on the improvement of agricultural financing and insuãance. After gaining independence the collective farms system in Georgia was dissolved and agricultural land was gradually privatized. This made agriculture to be mostly dominated by small subsistence farmers lacking accesses to rural credit and insurance. Current agricultural financial market and insurance is in the embryonic state that greatly hinders increase of production in the agricultural sector of Georgia. In the framework of the research 142 different size farms in five regions of Georgia (Adjara, Guãia, Kakheti, Samegrelo, and Samtskhe-Javakheti) were studied with main aim to reveal demand on agricultural loan and insurance as well as farmers' awareness of agro credits and insurance. At the same time, semi-structured interviews with representatives of financial institutions (commercial banks, microfinance organizations, credit unions) and insurance companies were conducted to study their strategies, vision and perceptions on agro financing and insurance in Georgia. Critical review of Eastern Åurîðåàï experience of transforming centrally financed agricultuãal sector of åñîïîmó to the market-based îïå in order to make comparative analysis for elaboration of general recommendations for Georgian policy makers was the integral part of the research. The study revealed a number of similar problems facing East Åuãîðåàï countries during the transition period in the 90s with current condition of Georgian agricultural financing and insurance.

Theoretical models determining seepage features in water supply canals under natural geotechnical conditions are applied in the isotropic water-permeable environment which limits the area of their application. Since the seepage factor is a permanently participating active component in formation of water balance of local agricultural (agro) systems, the determination of the water application rate is based thereon. Given the features of seepage, the questions connected with movement of water in porous systems of soil are the function of many interoperating factors. Hence, on the basis of the offered model, the calculation dependences of seepage velocity, seepage factor, water conductivity and porosity for real soils are obtained. Fig. 1, Ref. 5.

In soils, presented by the dispersed-hydraulic porous system, the migrated water gets specific qualities; therefore, definition of characteristics of water seepage in soils becomes complicated. Soils, which represent the multicomponent environment, consist of different micro- and macro- particles and the water migrated in these particles gets different qualities. Based on the above and the proposed model, the range of change and optimum values of active and passive porosity have been determined and the seepage velocity, initial gradient and irrigation mode are obtained.

With progressing earth history temperatures and precipitation have globally, regionally and locally changed. In addition to extraterrestrial reasons also terrestrial reasons like volcanism, forest fires, changes of global ice, snow and vegetation cover have caused such changes. For the last 100 years the global mean temperature has increased to actually more than 15°C, which is widely assumed to have not only natural but anthropogenic reasons: reduced water evaporation from agricultural land in contrast to natural forest, emissions of warmth and carbon dioxide especially in urban-industrial agglomerations, and the release of methane and nitrous oxide in agriculture are the most important impacts. It is assumed that in the 21st century the global mean temperature will rise by another 2-3 oC, mainly caused by a higher use of fossil fuels and an intensified conventional agriculture. Increased temperatures, higher CO2-concentrations near the soil surface and higher precipitation rates lead in principle to a higher formation of biomass. More crop residues and higher temperatures also stimulate the activity of soil organisms. Higher soil temperatures also stimulate chemical weathering. On the other side higher rainfall can wash out more solved nutrients. But the expected climate changes and their effects on soils can vary to a large extent. The predicted rising sea level will increase the flooding of coastal soils, so that dikes have to be built or heightened. Higher temperatures in coastal soils will intensify the microbial formation of greenhouse gases. Permafrost soils will melt so that their agricultural use may be partly possible.

With a view to enhancing agriculture in Georgia’s mountainous and foothill regions, the paper presents the organization of irrigation systems equipped with sprinkling machines, ruling out irrigational erosion and the risk of occurrence of freshets. Analysis is made of erosional conditions at sprinkling irrigation works, which directly depend on water infiltration in the soil during freshet processes. The greater the infiltration, the lesser is the possibility of accumulation of surface water. On the basis of the studies carried out, values of permissible intensity of sprinkling are obtained for slopes of various inclinations, according to soil type. Fig. 1, Tab. 2, Ref 4.

Development of saline lands of the Ararat Valley has certain difficulties caused by the great heterogeneity of the mechanical composition. Before chemical melioration, the processing of soda saline - salt licks - was carried out, depending on the lithological structure and mechanical composition. The optimum depth of tillage of soils is established. In case the surface clay layer makes 0-25 cm, the conventional 25cm-tillage is proposed; where the clay layer is at 50 cm from the surface,  the loosening takes place at the same depth, and if the clay layer is oa meter depth along the entire profile, a deep loosening is recommended at the depth of 100 cm.

The leading cereals in Georgia are incorporated in two groups: 1) bread grains and grouts; 2) legumes and sunflower seeds. At present, the yield of cereal is rather low in Georgia. The article lists several reasons that cause the lack of productivity. In order to dramatically increase production of cereals, multilateral measures should be carried out, such as: introduction of modern, improved agro-technologies, high-quality seed production, testing and zoning of varieties, etc. By means of the above, Georgia will come closer to European average level of cereals yield and it will be possible to secure the country with food and seed materials.

In recent years, frequency and harmfulness of grain pyrenophora has noticeably increased. It damages plants during all phases and in a number of countries occupies the first place among wheat diseases. One of the most effective and environmentally safe ways of struggle against the disease is growing of resistant species. In 2009-2011 researchers studied the level of resistance of wheat samples by two tested methods. The research revealed usefulness of selected methods and obtained results were the same. In both cases, according to the types of plant response, several groups were distinguished: recipient (50.6%), high-recipient (29.5%), moderately resistant (12.5%), average recipient (5%). Absolute resistance against the pathogen was revealed only in 2.5% of cases. Lit. 8; Fig. 2.

The development of maize seed-growing prospects in Georgia are considered. In order to increase maize-growing areas up to the level that existed 8-9 years ago, 200-220 thousand hectares of abandoned and turned into pasture lands should be cultivated again. Two different varieties - food and fodder maize - should be sown. Georgian varieties of maize, mainly cultivated in the western part of Georgia popular selected during 350 years are listed. Selective preservation of each variety is carried out by maize farmers within their own farms. At a scientific level this activity was carried out at the Institute for Agriculture and Ajameti and Senaki experimental stations, which are now closed. The work in this direction should be restored. The article names food and forage hybrids grown in Lomtagora, which ensure high and stable yields. Generally, out of 200 thousand hectares of maize fields, 90 ha should be sown with bread grain and 110 ha – with fodder maize. The authors state that the country needs 2,200 tons of hybrid seeds, and therefore the Institute for Agriculture, producer of 10 hybrids, should be restored and other organizations should be involved.

Stilbene-containing plate preparations have been extracted from the skin of industrial red-grape vine (Vitis vinifera L.) growing in Georgia. These varieties are as follows: Saperavi, Saperavi Budeshurisebri, Cabernet Sauvignon, Otskhanuri Sapere, Ojaleshi, Aladasturi, Chkhaveri, Aleksandrouli, Mujuretuli, Asuretuli Shavi. With the use of the high-performance liquid chromatograph (HPLC), their diversified stilbene spectra have been identified together with the identification of trans-resveratrol and its dimer ε-viniferin in them. There is a common regularity identified in the skin of all grape varieties; in particular, the concentration of trans-resveratrol much exceeds that of its dimer ε--viniferin. The quantities of identified stilbenes vary depending on the varieties and habitats of the vine. Studying the stilbene spectrum is the theoretical basis to explain the functional designation of grape and wines in respect of their curative and nutritional value. Tab. 1, Ref. 10.

11.g9.7.2. Plastid DNA sequence diversity in a worldwide set of grapevine cultivars (Vitis vinifera L. subsp. vinifera). /T. Beridze, I. Pipia, J. Beck, Shih-Chung Hsu, M. Gamkrelidze, M. Gogniashvili, V. Tabidze, P. This, R. Bacilieri, V. Gotsiridze, M. Glonti, B. Schaal/. Bulletin of Georgian National Academy of Sciences. – 2011. - vol. 5. - #1. – pp. 98-102. – eng.; abs.: eng., geo.

DNA sequence diversity was investigated at two plastid regions (the trnH-psbA intergenic spacer and the rpl16 intron) in a geographically diverse group of 113 cultivated grape samples. This group included 40 samples from Georgia, home to over 500 grape cultivars and the earliest archaeological evidence of grape domestication. The Greater Caucasus region in which Georgia lies is widely believed to be the area in which grape domestication began, and the study of genetic diversity in this region is viewed as key to understanding grape domestication in general. Four plastid haplotypes are evident in the 113 samples, and are designated by their character-states at each of the 3 polymorphic positions: (AAA) – 23 samples, (ATT) – 29 samples, (GTA) – 26 samples, and (ATA) – 35 samples. The AAA haplotype was only observed in Georgian samples. The observation that the Georgian cultivars exhibited both unique plastid DNA variation (the AAA haplotype) and all other observed plastid haplotypes is consistent with previous studies that have observed both unique and high levels of genetic variation in wild grape (V. vinifera subsp. sylvestris) in the greater Caucasus region.

Botanic-geographical diversity of floristic complex of the Caucasian rhododendron (Rhododendron caucasicum Pall.) on the Greater Caucasus has been studied. When specifying typical, characteristic species of the florocoenotic complex (thickets) of Caucasian rhododendron the distribution range of each species, coenotic role and coenotic links were taken into account. The research results have proved that despite quite frequent occurrence of around 100 species of various plants in rhododendron thickets on the Caucasus, the number of typical constant species of this complex is mainly composed of 14 species. These species are united in 11 genera and 8 families. The majority of these species (8 species) belong to Palearctic type of distribution range. In spite of the fact that by its bioecology Rhododendron caucasicum is close to Rh.ponticum, related to it and even often found in the composition of the Colchian forest as underwood, it cannot be considered to be a typical species of the Colchian forest. Typical hypsometric area of its distribution is subalpine and alpine zone between 1800-2700 m a.s.l. Fig. 1, Tab. 1, Ref. 32.

The experiment was conducted at Khan Gari Station Mardan-KPK-Pakistan during 2008 to evaluate the heterotic performance of some tobacco genotypes. Seven tobacco genotypes (KHG22, Spt G 126, K399, NC606, KHG21, KHG24 and Spt G 28) were crossed in all possible direct and reciprocal combinations. Forty two direct and reciprocal crosses along with their seven parents were space planted in randomized complete block design. Data were collected for days to flowering, leaf area, leaves plant-1, green leaves kg- 1, green leaves weight plot-1, plant height, internodal length, cured leaves kg-1 and yield kgha-1. Desirable heterotic effects were observed in all the traits studied. Greater values were observed for yield and green leaves weight plot-1. The cross NC606 x KHG21 showed high values for yield and leaf area. Spt G 126 x KHG22 gave high values for days to flowering, Spt G 126 x KHG24 was best for leaves plant -1and green weight plot-1and KHG21 x K399 was best for cured leaves kg-1. Generally, the heterotic effects of traits indicated the possibility of exploiting the hybrid vigor of the tobacco genotypes for yield and its components. Based on the findings of this study, the above mentioned crosses have potential for the improvement of various traits like yield and leaf area. Tab. 9, Ref. 13.

The considerable decrease of epizootic death and the number of sick animals as well as liquidation of sterility and dryness in cows and heifers are important reserves for increasing productivity of animal husbandry. The damage caused by sterility becomes apparent through the deficiency of calves, decreased milk yield, extra expenses on food and treatment that considerably increases the cost price of production. For the prevention and liquidation of sterility in cows and heifers a gynecological clinical examination makes it possible to establish the causes and take preventive measures. Ref. 7.

The paper analyzes the results of mass and output products of slaughter of young Caucasian Brown and of the Georgian (Caucasus) Buffalo. Found that the yield of the carcass, internal fat and slaughter yield of the Caucasian brown cattle higher is than that of the buffalo. However, the output of main products of slaughter is also higher in animals with higher body weight. In animals examined for each 100 kg of pre-slaughter live weight has 16.2-18.9 kg of food products (including 4.8 - 6.3 kg first and 11.3 - 12.8 second category). The output of slaughter by-products is slightly different. The exception is the skin, the output of which in the buffalo was higher by 3% on average compared to the same conventional cattle. This difference is most pronounced in animals with large body mass, and the elderly. Tab. 2, Ref. 6.

In pastures of Marneuli district (Eastern Georgia) suitable conditions for the development of invasive initial form of strongyles of the digestive tract and parascaris of horses are from April to October. In the summer months (average temperature, respectively, 20,1-23,5-23,4 °C) larvae of Strongyles and eggs of Parascaris reach the invasive initial form, respectively, for the 5-6 and 8-9 days. Their development stops in the first half of November. Eggs of Strongyles and Parascaris placed in the pasture during the winter months (average temperature, respectively, 2,2-0,2-1,2 °C), overwinter and in April after exceeding the average daily air temperature 8 °C begin to develop. In July-August, due to the high temperature, surface of the soil and drying none invasive larvae of Strongyles and eggs of Parascaris die out. Infective larvae of Strongyles migrate into the soil and accumulate on the roots of plants at a depth of 5-10 cm. In September they migrate back and are located on the stems of plants at a height of 5-10 cm from the soil surface. In October, after increasing the humidity in the pastures, the larvae migrate to the horizontal direction. On the stems of plants can be found within a radius of 10-15 cm from the test chamber.

The restriction of muscular activity is an important part of the hypokinetic syndrome. Hypokinesia leads to a reduction of energy consumption, reduction in bio-energy and intensity of structural metabolism in the muscles, the weakening of tonic impulses from the muscles, reducing the load on the skeletal system. The purpose of this paper is to study the dynamics of changes of some parameters of energy metabolism in rats and bulls with limited physical activity, approbation, and in an industrial environment adaptogenic drug Eleutherococcus extract. As a result of our studies, we observed a significant decrease in oxygen consumption, increased activity of catalase and glutathione content in the blood of experimental animals that is apparently due to a violation of mechanical ventilation and a decrease in the use of oxygen by the body tissues and cells, as well as changes in metabolism, indicating that shifts in the oxidation - reduction processes in the body and Eleutherococcus extract is the corrector of these negative changes.

Provision of wood is an important task to ensure growth of the country's industrial capacity. Industry and construction annually increase demand on wood, but in Georgia reserves of forest fit for wood cutting are practically exhausted, so this issue needs optimal approach - increasing wood reproduction and rational use of existing reserves. First of all, preference should be given to the use of deciduous species, since 75% of forests are deciduous, and only 25% - coniferous. Besides, coniferous wood in Georgia is of low quality in comparison with European and Russian species because of large amount of callosities. Deciduous species of wood has been used in cities and villages for domestic purposes and for making agricultural tools. Examples of industrial consumption wood (so-called business-wood) are packaging tare, railway sleepers, mining tunnels pins and scaffoldings, cellulose-paper products, etc. The paper provides a general overview and recommendations for the use of wooden timber in these fields. The main focus is restoration of Ingiri cellulose-paper factory, wooden tile and tare manufacturing enterprises working with local raw material which will meet requirements of the internal market.

Food production, processing, storage and distribution have all experienced profound changes in last decades due to forced globalization, shelf live extension, and often peculiar consumer demands. Manipulation of quality and safety terms along the food supply chain is prevalent. Food safety programs have to identify hazards, analyze them, evaluate the likelihood of their occurrence, and identify measures for their control. Being à food professional is à challenge and an opportunity to analyze processes and to understand how good and successful practices may be implemented and where food microbiology and its practitioners need to be actively involved in food safety management from "farm to fork": And with that, the food supply chain opens many dimensions of ethics considerations.

The complex outline of plot has a negative effect on the operational indices of machine-tractor aggregate, especially if the plot is located on the slope, because in the latter case the power stroke of aggregate is limited by the fact that it moves parallel to the horizons of the slope. In this respect, the connection between the MTA operational indices (particularly the coefficient of power stroke) and the loss coefficient of the curves with arbitrary location of rectangular plot on the slope (under some angle formed by any side of the plot and the slope horizon) are of great importance. It is revealed, that under this location of area those indices are getting worse. Fig. 4, Ref. 5.

Georgian National Academy of Sciences. – 2012. – v.6. - #2. – pp. 134-137. – eng.; abs.: eng., geo.

Short-stemmed super dwarf wheat “Gorda” is obtained via treating seeds of the French bred winter variety “Ducat” (released for distribution in Georgia) by 0.01% solution of chemical mutagen NMU – nitrosomethylurea. “Gorda” is a mutant form of winter wheat. The plant is bunch forming with reduced numbers and lengths of internodes and its maximal height is 26-27 cm. The leaves are broad and erect. The stems are short, firm and they hardly bend. The spikes are awnless, short (4-5 cm), flat and dense, in which grown underdeveloped florets are densely arranged on the spike rachis. The glumes of the spikelet are convex. “Gorda” is a late variety for as many as 10-12 days as compared to the regular local check varieties. It is susceptible to leaf rust and powdery mildew. Grain is shriveled and therefore the mass of its thousand kernels does not exceed 30 g. Grain raw gluten content is about 27-28%. “Gorda” represents breeding material of new inheriting property, which can be used as initial material for developing short-stemmed varieties with 2-3 height reducing genes.

In is shown that Georgia is noted for a great diversity of wheat (Triticum) varieties as compared with other countries of the world. Out of 24 wheat varieties, 14 (65%) have been found in Georgia; out of 6 elite varieties, 5 (over 83%) are in Georgia, for which reason Georgia is characterized of a high degree of endemism of natural wheat varieties. In addition, based on the endemic Georgian wheat varieties, many new immune species, varieties and forms have been selected. Georgia has been also recognized as a homeland of hybrid necrosis genetic phenomena and discovery of genes. The endemic varieties of Georgian wheat have played the most important in the evolution and selection of the wheat genus (Triticum).

The research shows that Georgia is a primary centre of the origin and diversity of cultivated wheat, distinguished from other countries by a high level of endemism. It is proved that Georgian endemic species of wheat have played an important role in the evolution of the genus Triticum and the process of wheat selection on a global scale. New species, genera, cultivars and varieties of wheat have been obtained on the basis of wheat species endemic to Georgia. Their genotype bears genes which allow obtain wheat species of a new type with high immunity and quality features. Issues of crossability of endemic species of Georgian wheat with other species as well as with aboriginal and selection varieties of soft wheat, germination capacity of obtained hybrid grains and viability of plants of the first generation are discussed in the present paper. Peculiarities of inheritance of economically important morphological traits in the first generation of plants are shown.

In Georgia, thermal power plants generate the bulk of electrical energy. The Ali-Bayramly HPP emits into atmosphere 120 mln m3 of smoke, which pollutes the environment every day. In calculation for fertilizers, it would form 300,000 ton of nitrogen fertilizer every year. At present, under way is the work to develop a technology of getting nitrogen fertilizer from the HPP smoke-gas emissions by means electrochemical and chemical reactions. The advantage of this method is that it is less power-consuming. Tab. 5, Ref. 6.

As a result of the ecochemical examination, the home-grown fruits of citrus plants were studied together with the imported ones (Satsuma tangerines and lemons “Newgeorgian” from Ajara, lemons from Greece, Washington Naver oranges from Ajara and Greece). Also analyzed were their ability for preservation, biochemical structure in dynamics, the structure of potential toxic and heavy toxic elements, taking into account the biological value and food safety. As a result of the research, it was determined that in concord with the standard the structure of glitsinec and vitamins C in the fruits grown in Georgia is higher than in the imported ones. As for the organic acids, raw materials of the cellulose and pectine, they were found to be more in the Greek products. The storeability of both the Georgian and Greek citrus plants was the same. The content of heavy metals Cu, Zn, Fe, Co, Mo, Pb, As, Hg, Cd, Cr did not exceed the permissible level. Dangerous nucleids Cs137 and Sr90 were not identified as well. According to the results of tasting, locally grown crops have a priority over the imported ones, for which reason they should be competitive both on the domestic and foreign markets, which are interested in getting ecologically safe and biologicall full-value products.
