The size of area of plantations of fast-growing tree species, established on agricultural land in the Czech Republic (CR), is on the rise. In order to gain saw timber, it is necessary to choose other species (example: Salix spp. and Populus spp., their resulting product is wood chips), one of which could be Paulownia spp. In 2015, an experimental plot with the species of Paulownia tomentosa and two hybrids of Paulownia Shan-Tong and Paulownia Hybrid 9501 were established in South Moravia. The plants were periodically pruned up to a height of 3 m. After six years, Paulownia Hybrid 9501 had mean height of 9.4 m and DBH of 12.8 cm, P. tomentosa 7.3 m and 10.3 cm, respectively, and P. Shan-Tong 5.2 m and 9 cm, respectively. These values are well below the average, in comparison with those declared by the sellers. The limited growth was presumably caused by less precipitation and a shorter growing season, in comparison with the climate characteristics of the humid subtropical zone in which Paulownia species originated. It appears that Paulownia Hybrid 9501 could grow in conditions similar to those in South Moravia, however, with a slower growth.
