Bio-methane Production from Sorghum Elite Lines under the Climatic Conditions of Pakistan


Abstract


Fossil foils are depleting dramatically to meet the ever blooming energy demands. Plant biomass is a best source
of renewable energy which can be used for bio-fuel production in order to meet the energy demands. Therefore,
this study was conducted for two consecutive years 2016 and 2017 to screen out best lines of sorghum for biomass
yield, chemical composition and bio-methane yield. The results revealed that tested lines had differential responses
for biomass yield, biomass quality and methane yield. Line 5018, performed remarkably and produced maximum
leaf area index (LAI), leaf area duration (LAD) and crop growth rate (CGR) followed by L-6024 whereas the minimum
LAI, LAD and CGR were recorded for L-5025. Maximum plant height, leaves per plant and dry matter yield ha-1 was
observed in L-5018, whereas the minimum plant height leaves per plant and dry matter yield ha-1 was recorded in
L-5025. Likewise, L-5018 also had maximum protein content, acid detergent fiber, neutral detergent fiber, lignin
content and ash content whereas the L-1914 had the minimum values for these parameters amongst the tested li-
nes. In addition, L-1914 produced maximum specific yield, however, L-5018 produced maximum methane yield ha-1
owing to higher dry matter yield ha-1. The results of this study suggested that L-5018 can be used to develop high
biomass cultivars with good methane yield potential.
