hyacinth
(WH) and
morning
glory
(MG)
Cow dung
Temperature,
25–35 °C
Time, 17 weeks
pH, 6–9
MG/WH, 100:0,
70:30, 50:50,
30:70, 0:100
MG/WH ratio of 50/50
gave highest biogas yield
of 0.29 L/kg VS fed per
day
Co-digestion had a
significant effect on TBC
(total bacteria count) and
not on biogas production
