With the help of soil evaporimeters about of the area 0.3 cu.m to compile the measurement material, in shape or from of twenty four hours sum of real evapotranspiration (ETR) the spring wheat variety Alfa, the spring barley variety Aramir and medium-late potatoes variety Atol and meadow for different of variants soil moisture, have obtained in years 1984-87. The statistical analysis of influence of the biological factor, selected meteorological factors and the soil water stocks on the real evapotranspirations of the wheat and the barley was realized. The coefficient of determination of biological factor for the wheat was: crop cover in natural environment 57 percent and for crop cover in the modulate soil moisture conditions 30 percent. For barley 69 percent and 80 percent. The soil water stocks to prove significant component of information about ETR only for wheat variant was 29 percent.
