Abstract

A phytosociological study of summer and winter weeds conducted in the rice fields of Duliajan during May, 1985 to April 1987 and Importance Value Index (IVI) determined for all these. There were 93 species in summer and those having IVI values more than 10 were Ageratum conyzoidesI (21.44), Polygonum hydropiper (18.97). Ludwigia parvifolia (17.61) and Paspalum scrobiculatum (13.37) and 16 species were there having IVI values less  than 2. Out of 74 species found in winter those having IVI values more than 10 were Ischaermum albens (18.55), Aeschynomene aspera (14.83), L. parvifolia (11.63), Heliotropium indicum (11.38), Digitaria sanguinalis (10.66), Hydrocotyl rotundifolia (10.51), P. hydropiper (10.41) and Scirpus sp.
