Periodical weed surveys were conducted during 2020-21in Jashore, Jhenaidah, Chuadanga, Meherpur and Khustia districts of Bangladesh to observethe severity and allelopathic effect of Parthenium hysterophorus on field crops. Parthenium infected the crops differently as observed in rice ( 8.75), maize (11.45%), lentil (12.45%), chickpea (32.40%), field pea (57.63%), jute (57.63%), cotton (13.45%), mustard (63.85%), sesame (17.50%), groundnut (28.35%), pointed gourd(11.50%), pumpkin (8.45%),onion (30.47%), garlic(26.25%), turmeric (17.50%), potato (38.75%), banana(24.33%), sugarcane (60.25%), napiergrass (55.00%) and marigold (11.25%).Allelopathic effect was examinedusing 5% aqueousleaf extract of P. hysterophorus ingermination test and results showedcomplete failure of germination in seeds of sesame, jute, pumpkin, red amaranth, chili, radish and tomato. Seeds of other crops germinated poorly in aqueous solution of parthenium with reduced radicle and plumule growth. Among the different crops, wheat had the highest reduction in radicle (96%) and plumule (94%) length compared to their control.
