Abstract
Bio-fuels are considered to be cheap, sustainable and more environmental friendly. Management considerations including
sowing method and suitable cultivar have considerable effect on the dry matter yield of plants which in turns influenced the
bio-fuel yield. Field experiment was conducted during 2016 and 2017 17 to assess the impact of sowing methods and cultivars
on biomass production, biomass composition and methane production from sorghum bicolor. The ridge sowing performed
better and resulted in taller plants with maximum diameter and leaves, dry matter and methane yield ha

. Moreover, the sowing
methods had non-significant effect on protein, sugar, ash, acid detergent fiber (ADF), neutral detergent fiber (NDF), and lignin
contents and specific methane yield. In case of cultivars Jawar-2011 performed significantly better with maximum plant height,
leaves, dry matter production, protein and ash concentration and methane ha-1
as compared to other cultivars. In conclusion,
ridge sowing and cultivar Jawar-2011 may be opted owing to high biomass production for increasing the methane yield ha-1
