Bioenergetic efficiency of drip irrigation modes of grapes
In modern conditions of water scarcity, the research of the energy evaluation of different modes of drip irrigation to reduce the consumption of irrigation water, material and energy resources, their effective use on irrigated grape plantations cultivated on the sandy chernozems of the left bank of the Lower Dnieper, where only irrigation is the guarantee of annual, constant high yield of vineyards. The purpose of the research was to study the energy efficiency of grape drip irrigation regimes, determine the volume and structure of resource costs, and the level of their payback. Field and comparative-calculation methods were used during the research. The establishment and conduct of experiments were carried out according to the methodology of the research case. The paper presents the results of research on the energy efficiency of drip irrigation modes of grape plantations. It is established that maintaining an unhindered moisture supply to plants during the growing season is achieved by an additional cost of 9.29 GJ/ha of anthropogenic energy. A more economical regime of humidity of the active soil layer during the growing season reduces energy costs to 5.2-7.7 GJ/ha. The structure of additional energy costs, regardless of the irrigation regime of plantings, is dominated by the energy of irrigation water - 80% and energy carriers - 18 %. The practical significance of the research is to conduct an energy assessment of different modes of drip irrigation of grapes to reduce the consumption of irrigation water, material and energy resources and their efficient use
