Mulberry trees have been recognized for their versatile applications in various industries, including the production of wood for energy purposes. The present study investigated the physicochemical properties of mulberry genetic resources and varieties in relation to their potential as a renewable energy source in the form of wood. This study also emphasizes the need to address challenges in effectively optimizing fuelwood production and utilization for a more sustainable future. The assessed physical properties of these resources revealed a moisture content, bulk density, basic density and specific gravity of 33.96-47.43%, 165.69-210.98 Kgm-3, 566.40-718.65 Kgm-3 and 0.40-0.66 respectively. Regarding chemical properties, the analysis unveiled ash content, acid benzene extractive, acid insoluble lignin and holocellulose of 1.10-2.39%, 2.21-3.77%, 20.91-28.45% and 68.59-73.28% respectively. On the basis of physicochemical properties M. macroura, M. laevigata, M. nigra, M.alba, G2 and M. australis are the most preferred energy plants among the 11species and 4 varieties studied. The physicochemical analysis of mulberry genetic resources and varieties sheds light on the promising potential of mulberry wood as an eco-friendly and renewable energy source. However, further research and development are essential to optimize fuelwood production, utilization, and deployment strategies, paving the way for a greener and more sustainable energy for future.

The physical and chemical composition of fuelwood species has significant influences on the energy value of woody biomass. The results of the current study indicates M. macroura is the most preferable species for energy production, followed by M. laevigata, M. nigra, M. alba, G2 and M. australis respectively. On the other hand, S36 is considered the least suitable species for energy output based on its rating. The promising species and varieties identified in this study can be recommended for inclusion in a fuelwood plantation establishment program for domestic and commercial cooking and heating. By incorporating into the plantation program, it is expected to meet the energy needs of both households and commercial establishments efficiently and sustainably.
