The research was conducted at the Agricultural Research and Development Station Oradea in the preluvosoil condition. It is considered that a crop receive the optimum regime of water if the moisture on watering depth is maintained between easily available water content and field capacity. The decrease of the soil water reserve on watering depth bellow easily available water content is considered ”pedological drought” and the decrease bellow wilting point is considered ”strong pedological drought”. Pedological drought was registered both in 2013 and 2014. In the period studied to maintain the water supply between easily available content and field capacity, the irrigation regime was different from one year to another depending on rainfall. In 2013 to supply optimal water consumption of sugarbeet were used 3.300 m³/ha water (were applied 8 irrigations), and in 2014 irrigation rate used was 3600 m3/ha and were applied 10 irrigations. Since pedological drought was present both in 2013 and 2014, irrigation is necessary to sugarbeet crop, as compared to unirrigated variant the yield gain are statistically significant.
