Physical properties of winter wheat stalk determined with the help of the resistance tests and ultrasonic tests are described with the use of the function of global approximation. Two dimensionless variables: coordinate of length and time of growth have been introduced. The possibility of using ultrasonic method in estimation of longitudinal rigidity and moisture content of stalk has been proven
