Irrigation efficiency depending on water cost

The article provides an analytical review of the achieved crop yields under irrigation in experimental and production conditions. For today, best experience use irrigated land indicates that, subject to all agrotechnical requirements, yield early grain crops reaches 8-10 t / ha, corn - 10-14 oilseeds 4-6 vegetable over 60 which is about 90% their productivity experiments scientific institutions. comparative assessment different climatic zones Ukraine for period most intense change shows that past thirty years, share Steppe zone has decreased from 45 35% total Ukraine. analysis service cost transportation water southern regions given. It was revealed despite a unified standard method calculating transportation, its price varies significantly by operational units State Agency Water Resources main factors fluctuations fees services are budgetary funding level operating organizations, providing these services, number transfers, volume actual on lands, areas area.
 economic efficiency when having other technological costs, taking into account depreciation capital investments, 4,0-5,0 UAH/m3, gross profit growing profitable field 35-40 % higher than rainfed agriculture. At 3,0-3,5 UAH/m3 capacity inter-farm network 60-70%, financial prerequisites will be created effective operation networks.
