The research concerning the irrigation of autumn cabbage was carried out on the preluvo soil from Oradea Agricultural Research and Development Station during 2013 and 2014. In order to maintain the soil water reserve on 0-50 cm depth easily available water content and field capacity irrigation water was required both in 2013 and 2014, 3.000 m3/ha and 3.600 m3/ha respectively. The total water consumption of the irrigated autumn cabbage increased in comparison with unirrigated variant of 108% in 2013 and of 131% in 2014. The contribution of the irrigation in the total water consumption (57% in 2013 and 53% in 2014) was higher than that of precipitations in the period from planting to harvesting, that is, 35% and 29%, and than that of soil water storage (7% and 8%). The water use efficiency improved significantly as a result of irrigation, the amount of cabbage head corresponding to 1 m3 of water used increased in comparison the unirrigated crop by 93% in 2013 and by 120% in 2014. The increase in yield corresponding to 1 m3 of irrigation water was 15.24 kg in 2013 and 13.97 kg in 2014.
