The article presents the method of determining the biological yield of roots and tops of sugar beet before the harvest, which is based on experimental data obtained directly in the field. To reduce the complexity of the process of sampling and their number while ensuring the reliability of the obtained result of the statistical processing of data by the Fisher test, which confirms that the size of the scoring area in the studied range (from 20 to 100 hectares) has virtually no effect on the magnitude of biological productivity, and the minimum number of samples is equal to thirteen. On the basis of data of field experiments the obtained formula for the coefficient terms of the biological yield in the assessment, depending on the specific conditions of beetroots.
