Abstract

The sorghum x sudangrass hybrid is highly significant as a biofuel crop due to its high biomass production, drought tolerance, ability to adapt to various climatic conditions, and high sugar content in its stems. This research aimed to determine the effects of six different nitrogen dose treatments on ethanol yield, yield parameters, and fertilizer use relationships in sorghum x sudangrass hybrid plants at two locations in 2021 and 2022. The experiment was established according to the randomized block design with three replicates. Nitrogen treatments were applied as N0 (0 kg da-1), N5 (5 kg da-1), N10 (10 kg da-1), N15 (15 kg da-1), N20 (20 kg da-1) and N25 (25 kg da-1). Juice ethanol yield (JEY), lignocellulosic ethanol yield (LEY), and theoretical ethanol yield (TEY) values varied between 123.8 - 219.0 L da-1, 522.2 - 955.1 L da-1 and 646.0 - 1174.2 L da-1, respectively. It was determined that JEY, LEY, and TEY values increased as the amount of nitrogen increased. In the correlation analysis, a high positive relationship was found between all traits except ADL. As a result of the orthogonal comparison, it was found that the amount of nitrogen dose should be increased for JEY, LEY, and TEY. Principal components (PCA) biplot analyses explained 92.9% of the relationships between the studied parameters and nitrogen dose levels. This study conducted over two years and in two locations, determined that sorghum x sudangrass hybrid cultivation could be realized in terms of bioethanol yield under different nitrogen dose levels. It also appeared that the ethanol yield potential is high
