Abstract:

A study was conducted to find out the weed floristic composition in coconut (Cocos nucifera L.) plantations of Sivagangai district in Tamil Nadu. Totally 92 weed species (75 species of dicots, 16 species of monocots and 1 species of Pteridophyte) of 81 genera belonging to 37 families were recorded in the study area. A total of 36 angiospermic families were found in the study area. Among them 33 families belonged to dicots and 3 to monocots. Poaceae (11 species) was found as dominant family followed by Amaranthaceae (7 species) and Convolvulaceae and Euphorbiaceae (each of 6 species). 19 families were found with single species.
