Abstract

In temperate climatic conditions, plantations of poplar and willow species provide sustainable production of biomass. Short rotation coppice plantations on agricultural lands have a great potential to increase the amount of biomass available for the production of biofuels, bioenergy and bioproducts. We studied and measured the growth of poplar and willow clones in two experimental research sites in Batys and Astaninskiy in the steppe zone of Astana in northern Kazakhstan. We measured tree heights, stem diameters at breast height and crown diameter. The mean height of 6-years-old trees of the “Kazakhstanskiy” hybrid poplar was 4.03 m in the Batys site, which is 1.6 m less than the height of poplars from the Astaninskiy experimental site that were measured in autumn. The results of this study show different reactions of selected clones/cultivars of poplar and willow to climatic conditions of northern Kazakhstan as well as their usability for biomass production in plantations under limiting hydrological conditions.
