Successful eucalyptus species for afforestation and development of green spaces under irrigation with sewage

Due to the wide variety of eucalyptus species and their various ecological requirements, it is necessary to select the appropriate species for afforestation and development of green spaces through compatibility testing. Accordingly, the compatibility of various species and provenances was considered. This research was carried out in the climatic conditions of Yazd and through irrigation with wastewater during 2009 to 2018. The experiment was carried out in Yazd Wastewater Treatment Plant with a randomized complete block design and four replications, with eight species and provenances, at 36 plants in each block at a distance of 3 × 3 m. Species and provenances were E. rubida, E. saligna, E. saligna20762, E. macarthurii, E. viminalis, E. sargentii, E. camaldulensis and E. microtheca. The results of the study in the first phase of the experiment showed that E. camaldulensis, E. sargentii and E. microtheca had higher and significant establishment rates (98.6, 95.1 and 42.9%). According to the results, the yield of E. camaldulensis was superior to the other two species. Our results clearly showed that in case of healthy roots, all three species showed a high potential in coppice production
