The Behaviour for SRC Willow Inger in Experimental Trial Ghilad, Romania

Abstract

The use of bioenergy are increasing in many European countries and an important role will be played by biomass produced in willow SRC. Short Rotation Coppice (SRC) willow was developed in Sweden in 1970 and it is cultivated for the production of wood chips. In Romania there are not more than 800 hectares, half of them are in Banat area. In this context assessing the biomass yield in the different experimental trial are very important. Research have been made in three SRC willow experimental trials established in Ghilad, Timis County, Romania. The material consist in willow Inger. All three trails have been established in the year 2011 but harvested in different years. Measurements and observation were made on 15 plants at the end of the 2014 season. One plant from each experimental trial has been harvested and then weight in order to establish their aboveground and underground biomass. Research highlight significant differences according with a number of shoots per stump and shoot diameter according with harvested year. According with stump age and the number of harvests, significant differences were established for quantitative character diameter. There also have been put in evidence the differences between the aboveground and underground biomass for different willow age. This screening about biometric characteristic and aboveground biomass showed high value for willow SRC harvested every year. We have to notice that any economic aspect have not been evaluated
