TOPOGRAPHICAL AND PEDOLOGICAL STUDIES REGARDING THE WATER CONSUMPTION AT SOME LEGUMINOUS FODDER PLANTS LOCATED IN A EXPERIMENTAL FIELD IN CHINTENI, CLUJ COUNTY

As is known, the water consumption of plants, synonym with the evapotranspiration (ET), is the quantity of water extracted from soil by the plant transpiration, at which is added the direct evapotranspiration from the surface of soil. The progresses from the last years revealed that the water factor is a limitative element for the production, especially in the dry and semidry areas of the world. The importance of this factor grows even more in the case of fodder plants, especially in the case of perennials plants, because their yield comprise the total vegetal mass, which require water on the whole vegetation period, when the plants renew for 4-5 times after each harvest.
