A complex indicator of a barley variety's ability to produce grain yield, determined through structural analysis of spike elements, 1000-grain weight, and final yield per unit area.

where this is mentioned in the description.
Barley productivity is assessed by a combination of structural elements, including the number of productive stems per unit area, the number of grains per spike, and the 1000-grain weight. The final yield is expressed in centners or tonnes per hectare and is determined during competitive variety trials on plots with mandatory replication to account for soil heterogeneity.
The assessment of a variety's productivity level is relative and is conducted by comparing it with a zoned standard in a specific cultivation zone. In addition to yield potential, agronomists consider the homeostaticity and stability of the variety, which allow for predicting results under various climatic conditions and varying levels of agricultural practices.
