Item Potential of Salvinia mo lest a (African payal) as an alternative and supplemental feed stock to cattle dung for biogas production(Kerala Agricultural University, 1988) Sankaranarayanan, M R; John Thomas, KThe floating aquatic weed, Salvinia molesta (locally known as 'African payal') could be easily fermented and hence is a very good material for biogas production. The average gas production per kg of oven dried salvinia weed was 336 litres with a retention time of 50 days. The gas generation could be doubled when mixed with fresh cowdung in the ratio 1:1. Thus we can make up the shortage of cowdung with the use of salvinia weed for biogas production, wherever it is available.
