ABSTRACT: In present study invasion of Parthenium hysterophorus L. and its
impacts on agriculture fields will be done in different cultivated crops in Bilaspur. The present work deals with
diversity and distribution of weeds species in cultivated fields of Bilaspur C.G. A total number of 28 species under 27
genera and 16 families was distributed
in three study sites (Koni, Sakri & Kota) of cultivated fields in Bilaspur C.G. These study sites were located
in different altitudinal zones responding different
conditions in the this study. The number of species per sites ranged from 13 to 24. In the Sakri,
number of species was ranged from 17 to 27, and the relative density of plant
species ranged between 0.77 (Heteropogon contortus, Solanum surratense, Vernonia cinneria and Leucas
aspera) and 22.92 (Parthenium
hysterophorus). In the Kota, number of species was ranged from 14 to 28, and the relative
density of plant species ranged between 0.85 (Ageratum conyzoides, Heteropogon
contortus, Triticum aestivum) and
29.06 (Zea mays) and 30.91 (Parthenium hysterophorus). In the
Agriculture field, number of species was ranged from
15 to 28, and the relative density of plant species ranged between 0.58 (Leucas aspera) and 26.23 (Triticum aestivum). Present work will
give the information that weeds are harmful to herbs, crops and medicinal
plants. Parthenium weed can suppress
and crowd out other weed species, and could form a single dominant population
in the invasion area, causing serious
threat to plant community biological diversity.
