The average yield of spelt is 20–30 dt/ha, with a growth potential of up to 50 dt/ha under favorable conditions. Evaluation of this metric accounts for grain output from hulled or naked forms and the necessity of harvesting in the form of spikelets to prevent fragmentation.

crop Spelt,
where this is mentioned in the description.
When determining the yield of spelt, factors such as the number of productive stems, spike grain set, and 1000-grain weight are considered. An important technological aspect is the separation of accounting for hulled and naked forms due to differences in marketable grain output and the complexity of post-harvest processing. For yield assessment, it is recommended to harvest in the form of spikelets, which requires specific settings for the combine harvester's threshing mechanism, such as reducing beater speed and increasing concave clearances.
Average crop productivity metrics range from 2.0–3.0 t/ha, reaching 5.0 t/ha or more under optimal conditions. Despite the fact that the yield potential of spelt is lower than that of intensive soft wheat varieties, the economic efficiency of the crop is maintained by its high competitiveness against weeds and resistance to diseases, which minimizes production costs.
