The paper is based on the research carried out during 2005-2007 on the preluvosoil from the Agricultural Research and Development Station Oradea. The weeds determined yield losses between 43.1% and 85.8% in non-irrigated conditions and between 45.2% and 79% in irrigated conditions. The weeds determined the decrease of the water use efficiency with 42-86.3% in non-irrigated conditions and with 44-79.3% in irrigated conditions. In all the years the weeds determined the decrease of the irrigation water use efficiency; the biggest difference between the weeding variant and the variant without weeds was registered in 2007 and it was of -70.4%.
