Bilaspur is district of Chhattisgarh and is situated between 210 37, to 3707, north latitude and 81012, to 81040, east longitude. The texture of soil varies from matasi to kanhar and pH range from 5.9 to 7.1 with a mean value of 6.2. A climatic condition is favorable to weed and crop growth. Climate is generally wet and humid. Paddy is the main crop grown in this area. The crop is heavily infested with the weeds. The losses caused by weed flora of the two rice cultures i.e. dry seeded and transplanted. Present study has been carried out with the view and floristic diversity of weeds of DSR and TPR were studied during 2021-22. Eighty weed species belonging to 64 genera of Angiosperms, 01 genus of pteridophytes and 03 genera of Algae are found to be associated with paddy crop. Fourty one and 39 weed speices were found associated with DSR and TPR respectively. The most dominating families in term of their weediness were Poaceae,Cyperaceae and Asteraceae. Four genera of family Cyperacere were distributed in 09 species, and 10 genera having 12 species of poaceae were recorded. Echinochloa colona, Cyperus iria, Cyperus flavidus, Cyperus rotundus, Ageratum conyzoides, Cynodon danctylon and Saccharum spontaneum were commonly distributed weed species. Dicot/Monocot ratio 1.13 (genera wise) and 0.818 (species wise) was obtained.
