Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
Bilha block is located in Bilaspur district of Chhattisgarh state. The geographical situation of the district is 21˚37’- 23˚7 North latitude and 81˚12’-81˚40’ East longitude. Phytosociological survey done in the month of October-November 2016.The climatic and edephic conditions are favorable in vegetational growth. The total rainfall in year 2016 are1259 mm. The maximum and minimum temperature of district is 44 ˚c and 24 ˚c. Weeds are unwanted plants which grow automatically in vary widely in variable environmental condition to form vegetation. Growth parameter indicate the weeds have decreased the soil moisture and nutrients, But weeds are most important factor of plant biodiversity. Phytosociological analysis of weeds is essential to establish any ecological conclusion. Standard ecological parameters such as % frequency, density, abundance, basal cover, relative frequency, relative density, relative dominance and Important value indicates (IVI) are calculated by formulae given by Mishra et. All (1968), by using 50 x 50 sq.cm quadrat general survey indicate more than 50 species are obtained in different families obtained 10 species are found in potential weed. Identified weeds species are: Cynodon dactylon ,Acanthospermum hispidium , Portulaca oleracea , Achyranthes aspera , Sida acuta , Sida rhombifolia , Parthenium hysterophorus , Cassia tora , Andropogon virginicus , Xanthium strumarium IVI ranges of potential weeds are 8.157 to 18.190.
