    IRRIGATION REGIMES AND YIELD OF BERRIES IN DRIP IRRIGATION CONDITIONS AND WATER DEFICIT

    Science. Business. Society., Vol. 3 (2018), Issue 4, pg(s) 171-172

    The increasing water deficit requires studies to optimize irrigation regimes and water-saving technologies to achieve economy of irrigation water at an acceptable yield level.
    In order to establish the irrigation regime in the field of “Chelopechene” Experimental Field, Sofia, there have been researches, examining different regimes – from full satisfaction of the daily needs of culture for water to irrigation with reduced by 20% and 40% water application rates.
    On average, over the survey period, the highest yields were obtained with the irrigated wit 100% water applicatipn rate. Reducing the irrigation rate leads to a corresponding reduction in yields and affects the quality of production. The application of regimes of irrigation with reduced iwater applicatipn rates is recommended  only in the case of water deficiency.

    SERVICE CO-OPERATIVES IN UKRAINE: TECHNICAL AND INFRASTRUCTURE DEVELOPMENT

    Science. Business. Society., Vol. 3 (2018), Issue 4, pg(s) 169-170

    The development of agricultural service co-operatives in Ukraine is one of the priority directions of the state agricultural policy. The cooperation of small and medium-sized agricultural producers in the dairy, horticulture, vegetable and grain sectors is the key to not only economic, but also social development of rural areas. Increasing the competitiveness of farmers involves significant investments into infrastructure and technology, while the cooperative model enables farmers to receive high-quality technical and logistic services at affordable prices and with affordable start-up investments.

    JUSTIFICATION OF SCIENTIFIC AND PRACTICAL APPROACHES TO RATIONAL USE OF STRAW AND PLANT RESIDUES

    Science. Business. Society., Vol. 3 (2018), Issue 4, pg(s) 165-168

    In the paper, the current situation in the production of crop growing by-products in Ukraine is examined. The potential output of crop growing by-products in various regions of Ukraine, part of which could be allocated for energy production, is determined. The fuel properties of the main types of biomass are presented. The state-of-the-art approaches to the use of straw and plant residues in agriculture are analysed. The possible ways of utilising straw and plant residues in crop growing for maintaining and regenerating the fertility of soils, in livestock husbandry as bedding and a supplement to coarse fodders and in heat power industry as an energy source for the production of thermal power are established. The state-of-the-art technologies and machinery for the rational use of straw and plant residues are described. The need for additional research into what plant residues and what quantities of them can be reasonably used for the fertilisation of soils, taking into account the saturation of the crop rotation systems with cereal crops, the limitation of the phytopathogenic load on grain varieties, the development of weeds, the management of the soil’s nitrogen status under different soil and climate conditions.

    RO-RO SHIPPING NETWORKS IN THE BLACK SEA REGION AND PORTS CONNECTIVITY: COMPARATIVE ASSESSMENT

    Science. Business. Society., Vol. 3 (2018), Issue 3, pg(s) 124-127

    The present article presents in detail the concept of ports connectivity of the ro-ro shipping networks in the Black Sea region. The existing ro-ro services in the region are studied in terms of transportation availability, frequency and capacity. A set of port connectivity indices is applied for measuring the interconnections between the ports in the region via ro-ro services. The results demonstrate that the roro shipping network in the region has a potential for development and despite the low cargo volumes, low level of capacity utilization and lack of efficient hinterland connections of ports.

    PROSPECTS FOR THE TRANSPORTATION OF LIQUIFIED GAS FROM THE CASPIAN REGION TO EUROPE

    Science. Business. Society., Vol. 3 (2018), Issue 3, pg(s) 122-123

    Georgia proposes to supply Caspian liquefied gas to the European market via the alternative route – by building a terminal for exporting liquefied gas on the Black Sea coast. Compressed gas will be delivered from Georgia to the Romanian port of Constanta on tank vessels.
    Kazakhstan regards this route as an option of delivery of liquefied gas to the world market.
    Turkmenistan is also studying options for exporting liquefied gas through Azerbaijan and Georgia.
    To participate in the project as a vendor, Turkmenistan could supply liquefied gas by the Caspian sea to Azerbaijan for its further transit through Georgia to Europe.

    INFLUENCE OF THE WORKING ENVIRONMENT ON SAFETY AND HEALTH PROTECTION AT WORK AND PERFORMANCE OF THE EMPLOYEES IN AN OFFICE SPACE

    Science. Business. Society., Vol. 3 (2018), Issue 3, pg(s) 115-121

    Currently, most employers ignore the fact that colors affect the behavior and thinking of employees in the work process. Workers are austere, colors, and they are places where employees only routinely perform tasks. In such an environment, employees can not feel good, do the best they can and work safely. It is important for employers to realize that by creating suitable working conditions they will help their employees to better manage their job tasks. Their performance will improve, they will work safely and significantly help in the development of society. The article deals with experiments that deal with the performance of test people who perform specific activities with different color backgrounds. This section evaluates the measured values and determines which colors affect the lowest performance, which colors are disturbing and cause many mistakes, human workplace problems, which can lead to arguments or even aggression. But also which colors can help achieve the highest efficiency that positively affect staff performance, support thinking and develop creativity, improve relationships and create a comfortable atmosphere.

    EVAPOTRANSPIRATION AND BIOPHYSICAL COEFFICIENTS OF RASPBERRIES GROWN IN DRIP IRRIGATION

    Science. Business. Society., Vol. 3 (2018), Issue 2, pg(s) 78-81

    In order to establish the aggregate and average daily values of raspberry evapotranspiration in an experimental site in the village of Chelopechene – Sofia, drip irrigation studies were carried out on a replanting variety "Liulin" under different irrigation regimes – from full satisfaction of the daily needs of the culture from water to irrigation with 20% and 40% irrigation norms. The meteorological conditions during the study period showed an influence on the sum of the sum and day-to-day values of the culture evapotranspiration.

    On average, during the research period, the total evapotranspiration rate for the raspberry vegetation period is 4730 m3 / ha, with the main part being formed by the irrigation rate – 60% and by rainfall – 40%

    For the needs of practice and design, the ten-day values of the biophysical coefficients Z and Kp were calculated over a five-year period.

    PAINT COATINGS FOR CORROSION PROTECTION OF LIVESTOCK MACHINERY

    Science. Business. Society., Vol. 3 (2018), Issue 2, pg(s) 69-70

    The machinery in livestock farming works in a highly aggressive environment, increased ammonia content and high humidity. Anticorrosive protection of machines and equipment is widely used on the basis of lacquer materials. Their effectiveness is mainly determined by the selection of the varnish materials according to the type and degree of corrosion hazard.

    Modern lacquer-based materials based on melamine, pentaftal, nitrocellulose, butyl methacrylate, chlorovinyl, epoxide and other resins are characterized by high protective properties and the possibility of renewal.
