Abstract
A survey on weed in mungbean field was carried out at Joydebpur, Barisal and Ishurdi areas (AEZ 28, 13 and 11 respectively) during kharif-1 season of 2008 to identify the major weed species associated with mungbean under different agro-climatic regions. Six to eight farmers’ fields were randomly selected from each location for data collection. Variability of weed species was observed in different locations. The maximum weed infestation in mungbean was found at Ishurdi (360 m-2). The dominant weed species was Cyperus rotundus (Mutha) with summed dominance ratio (SDR) values of 39 to 67. Echinochloa crusgalli (Boro shama), Digitaria sanguinalis (Anguli) and Cyperus rotundus were the dominant weeds at Joydebpur with SDR values of 44, 25 and 21 respectively. But at Barisal, Digitaria sanguinalis, Parapholis strigosa (Chela) and Bagajoga (Local name) were found dominant weeds with higher SDR values.
