Cheap and ecologically friendly energy resources are vital factors for sustainable development of the national economy. Due to global climate change and the depletion of fossil fuel resources, renewable energy may promote energy security and decrease harmful emissions. This paper aims at studying strategic directions for biofuel production and its utilization in Ukraine. On the basis of the literature review, steady world trends of renewable energy use have been revealed. Production of energy resources and the efficiency of their utilization have been analyzed. The modern aspects and priority of bioenergy use are highlighted. To evaluate the competitiveness of biofuels and their influence on energy security and ecological safety, organizational and managerial measures have been proposed. ...
The article concerns logistic procedures in the promotion of agritourism services used by farmers engaged in agritourism and by agritourism associations, local authorities in municipalities and agricultural advisorycenters. On the basis of the literature, various promotional instruments used by rural service providers and by these entities in the communication processes with the market were shown. Logistic aspects concerning planning and implementation of agritourism development were presented, mainly the role of agritourism information and promotional activities in these processes. Farmers providing agritouristic services most often use various forms of promotion. Among them, they use online advertising, publishing houses, including catalogs, trips to gritourism fairs, personal sale and different forms of public relation. In the agritourism promotion they often have support from local authorities, agritourism associations and agricultural advisory centres. All promotionalactivities undertaken by farmers themselves and with the support of these entities constitute an important part of agrotourism logistics. ...
We have established the importance of proper vine pruning techniques depending on individual grape variety characteristics and its influence on crop formation and quality of the grapes. The technique of studying the influence of the length of the vine pruning on the qualitative indices of the fruit of the grapes has been proposed. Field research was carried out in 2014-2016. Agricultural technology in the experiment is commonly used for forest-steppe. The vines are planted on the plot without irrigation, the shape of the shrubs is harp multy sleeved with a knot of substitution, sheltered on a vertical trellis of 1.5 m heigh. The methods thatcan be used to increase the yield of grape varieties in the Poltava region (Ukraine) have been analyzed. It has been established that the coefficient of fructification of apical buds predominantly correlates with the actualyield, which allows to use this link to predict yields by grape varieties. The justification and characterization of the selected methods of vine pruning, which would ensure the obtaining of high sustainable yield and fruit quality, as well as the economic efficiency of growing grapes, have been given. ...
