Effects of nutrient supply and planting material quality on yield and survival rate of a short rotation coppice culture in Hungary

Abstract: In May 2011, a short rotation woody energy plantation (SRC) was established near Dejtár village in Northern-Hungary.The goal of the experiment was comparative analyses of different fertilization treatments on three clones of Populus (AF2, Monviso, Pannonia) and one Salix cultivar ('Dékány').We used three fertilization treatments: (1) 5 t ha -1 of wood ash, (2) 40 t ha -1 of farmyard manure and (3) both 5 t ha -1 of wood ash and 40 t ha -1 of farmyard manure.The Monviso clone had the highest survival rate (92%), followed by Pannonia (80%) and AF2 (78%).Initially, the white willow 'Dékány' cultivar was also included in the experiment, but due to differing site preferences of this cultivar, it was not viable in the area.Based on the data of the first three growing seasons, it was demonstrated that the important nutrients had already been present in optimal amounts from the start of the experiment, and their contents were increased due to the treatments.At the end of the first growing season, the effect of the fertilization treatment could not be detected, but by the third year the results showed a significant positive effect.Already in the second, but mostly at the end of the third growing season, the wood ash + manure fertilizer treated plots showed significant increases in height growth and biomass yield.
