A poly-bag experiment was carried out during March to May 2017 in ‘West Central Table Land Zone’, Odisha, India in complete randomized design with fly ash, vermicompost and virgin soil each at 0%, 20%, 40%, 60%, 80% and 100% by weight to study their effects on the floristic dynamics of the weeds in rice nursery soil. Fly ash and vermicompost at different levels in rice-nursery have their significant influences on the floristic composition of weeds. No broad leaf weed or grass or sedge could emerge in rice nursery in absence of vermicompost except in 100 % soil with only very limited weed flora. The maximum number of broadleaf weeds emerged in soil with 80 % vermicompost and the maximum number of grasses and sedges emerged in 100 % vermicompost and also in soil with 60 % vermicompost by weight. The highest dry matter of weeds was recorded in 100 % vermicompost.
