Parthenium hysteroforus commonly known as Congress grass, Carrot grass, Chatak Chandni etc. is a menace to farmland, human-beings, animals, environment and biodiversity. About 35 million hectare of land is so infested with Parthenium. Previously it was a problem of waste and barren land but now Parthenium is a big problem in each and every crop field, orchards and even in the forest.
Due to continuous and large-scale use of chemical fertilizers, fertility of land is decreasing gradually. Therefore, bio-fertilizer is a boon for soil health. The demand of bio-fertilizer is increasing day by day. We can make bio-fertilizer from abundantly occurred biomass of Parthenium. By making use of this weed, at one hand we can increase the productivity of our crop land by weeding out of this weed while at other hand we can even earn money by making compost on commercial basis from this waste material.
