A preliminary study on the effect of different nitrogen levels on biomass yield and some yield characteristics of elephantgrass ( Miscanthus X giganteuss ) used as an energy crops

This study was conducted to determine the effect of nitrogen levels on the biomass yield and some yield parameters of elephantgrass (Miscanthus x giganteus) (Freedom cv.). The experiment was carried out at Ege University, Faculty of Agriculture, Department of Field Crops, Izmir/Turkey, during the summer growth seasons of 2017 as a pot experiment grown under outdoor. In the experiment, elephantgrass rhizomes were planted with different fertilization levels of nitrogen (0, 50, 100, 150, 200, 250, 300 kg/haN). Results indicated that the effects of nitrogen treatments were significant on some characteristics tested in the experiment. Application of the higher rates of N treatments increased the biomass yields compared to the control treatment. Based on these results, 150 kg/ha N was proved the best fertilizer levels for elephantgrass biomass yield under Mediterranean ecological conditions of Izmir.
