The paper presents research results on stand structure and yield from black locust (Robinia pseudoacacia L.) stands of various initial spacing at age 7 and 12 years. The investigation showed that there is no reason to increase the planting stock number per hectare above 4500-5000 in the afforestation phase (depending on site conditions) and that the growing space of seedlings should not be more than 2.0-2.2 m2 per individual. Close correlation was found between the stem number per hectare and volume of mean tree, as well as the reduced stem number after cleaning and the rate of changes in mean stem volume. The optimum stem number after cleaning is around 1700-1800 per hectare in stands of yield classes III-IV.
