ABSTRECT
The present investigation has been carried out of diversity assessment of grasses in

southern part of Jabalpur district, Madhya Pradesh. A total 29 Genera and 36 species have
been enumerated from study sites, belonging to Poaceae (Gramineae) family.

-1
The highest average grass density (125600ha ) was assessed in Dichanthium
-1
-1
annulatum, followed by Brachiarea ramose (61600ha ), Sporobolus diandrus (49600ha ),
-1
-1
Cynodon dactylon (42000ha ), Paspalum distichum (30000ha ), Digitaria ternata (26400ha -
1 ). The lowest density was recorded for Dinebra retroflexa, Eragrostis brachyphylla and
-1
Eragrostis uniloides (each 6000ha ). Cynodon dictylon is the most frequently occurring grass
species in southern area of Jabalpur, with frequency of 36%, followed by Dichanthium
annulatum (32%), Brachiarea ramosa and Digitaria ternate (each 28%). Borthriochloa

pertusa, Dactyloctenium aegyptum, Dinebra retroflexa, Eragrostis brachyphylla, Eragrostis

uniloides, Imperata cylindrical, Melanocenchris jacquemonlii and Sateria gluaca are the
least frequently occurring species with 4% frequency. The highest IVI (31.49) has been

recorded in Dichanthium annulatum and the lowest IVI (3.49) in Dactyloctenium aegyptum.
Richness or diversity of grass species has been indicated by Shannon diversity index

'
(H) with a value of 3.201, whereas Simpson index (D) value is 0.938. The higher evenness of
grass species has been computed a value of 0.428. Value of standard deviation (55.281)
clearly shows the higher dispersion of the grass species.

Phyto-sociological parameters of grass species such as density represent positive
correlation with frequency, abundance and IVI.

Agglomeration coefficients have more dissimilarity in grass species (Sateria glauca,

Sateria intermedia, Sehima nervosum, Sorghum bicolor, Sorghum halepense, Sporobolus
diandrus, Sporobolus indicus and Themeda quadrivalvis).
