Abstract

An experiment was carried out at the Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh during the period from July to November 2011 to investigate the allelopathic potential of different weeds on aromatic rice cv. BRRI dhan 50. Six weed species viz., joina (Fimbristylis miliacea), mutha (Cyperus rotundus), khude shama (Echinochloa colonum), sobuj nakful (Cyperus difformis), foska begun (Physalis heterophylla) and chapra (Eleusine indica) were used in the experiment to observe their allelopathic effects on seed germination, root length, shoot length and dry matter production of aromatic rice. The result depicts that unboiled and boiled weed extracts have negative influence on germination and primary growth of aromatic rice. The ranking of weed species in respect of inhibitory effect on seed germination were Echinochloa colonum > Cyperus difformis > Cyperus rotundus > Eleusine indica > Fimbristylis miliacea > Physalis heterophylla. Khude shama (Echinochloa colonum) and sobuj nakful (Cyperus difformis) had strong detrimental effects on the early growth of aromatic rice. The experimental results proved that it was important to exclude two allelopathic weeds namely khude shama (Echinochloa colomum) and sobuj nakful (Cyperus difformis) in the aromatic rice field. So, it can be concluded that these two weeds should be avoided from the aromatic rice field during land preparation.
