ABSTRACT

From October 2021 to September 2022, weed flora variation was studied in eight selected crop fields in the Joypurhat district of Bangladesh. These fields included rice, wheat, potato, maize, brinjal, chili, black gram and sugarcane. There was a total of 77 weed species that belonged to 27 families were recorded and described below 53 genera. Asteraceae accounted for 20.78%, Amaranthaceae for 6.49%, Poaceae for 15.58%, Euphorbiaceae for 6.49%, Cyperaceae for 3.89%, Marsileaceae for 6.49% and Solanaceae for 3.89% of the influential families. Among the species that were found Anagalis arvensis, Euphorbia helioscopia, Glinus oppositifolia, Senna tora and Ludwigia perennis were all listed as rare species. The survey found the most species in sugarcane fields (94.80%), followed by wheat fields (84.42 %), maize fields (81.81%), brinjal fields (77.92 %), chili fields (68.83 %), potato fields (64.96 %), rice fields (46.75%) and black gram fields (45.45 %). Monocot species had less influence than dicot species. Scientific name, local name, flowering time and family name were recorded of each species.
