Fibrous residue from water hyacinth harvested at six different maturity stages was assessed for their mineral content and antinutritional factors. The leaf dry matter at six maturity stages were found to be 6.28, 6.80, 7.13, 8.43, 9.65 and 10.43 per cent, respectively. Maximum calcium and phosphorus contents of 1.25 and 0.69%, respectively were found in the fibrous residue obtained from the foliage of sixth maturity state (November, 25). The antinutritional constituents such as polyphenol and nitrate content ranged from 3.43 to 4.77 g/100g and from 0.55 to 1.12 g/100g, respectively. The antinutritional factors were recorded minimum in the fibrous residue obtained from the foliage of first maturity stage i.e. April 15 harvesting date.
