Crop Residue Management through Its Alternate Use: A Case Study in Koshi Zone of Bihar

Biomass assessment study in Koshi zone of Bihar was carried out at regional Research Station, Agwanpur, Saharsa during 2015-2016. Study was focused only on ACZ-II in first phase. For the study of different fate of residues of crops in Zone-II of Bihar, it was concentrated in the districts of Purnea, Katihar, Saharsa, Supaul, Madhepura, Khagaria, Araria and Kishanganj. In first scenarios were feeding of livestock with dry biomass for 200 days in a year, it was observed that all the districts were deficient in providing biomass to live stock. However, in second scenario were feeding of livestock with dry biomass for 300 days in a year, all the district except Araria were deficit in providing biomass to livestock. There is no such problem arises for management of excess crop residue in these areas as these areas are already in deficit condition for biomass.
