In the present paper there are presented the results of the researches performed in the Northern Băragan area, where, at present, it is cultivated the biggest part from the ploughland. The researches were performed in the years 2016-2020 at “Famagrion SRL” Commercial Company, under the representative field conditions of the dry steppe from Bărăgan. It was used the recommended technology fir this area. The differentiation of the experimental modalities was made taking into account the maintenance of the moisture of the soil between the water capacity from the field and certain minimum limit values in relation to the accessible moisture of the plants (available water, the interval of the active moisture), at the developing depth of the main mass of roots. The management of the irrigation system (application of the watering) was based on the moisture measurements from the soil carried out decadal in three repeated intervals for each modality. These measurements allowed the calculation of the water consumption through the balance method. For the calculation of the water consumption, it was taken into account the total of the rainfall amount. The results obtained certify the opportunity of irrigating these plants in order to ensure the moisture and compliance of the requirements regarding the water consumption for establishing the increased productions, both on normal soils and those affected by the salinization processes.
