The paper studies the influence of organic and organic-mineral fertilization on water use efficiency and irrigation water consumption based on researches carried out in the experience field at Agricultural Research and Development Station Oradea. Following consumed a higher quantity of water from soil reserve and the values of total water consumption increased. Fertilization with manure determined the accumulation of a high quantity of water in the soil reserve. In average on the period 2013-2014 under unirrigation conditions the fertilization with manure 30 t/ha was obtained an yield gain of 29% in comparison with unfertilized variant; through organic-mineral fertilization the yield gain was higher (59%). Organic fertilization and especially organic-mineral fertilization determined increasing of water use efficiency.
