November and is followed by Cenchrus sp. (4.8 in
September to 12.9 per cent in November) and
Chloris barbata (5.9 in September to 9.8 per cent in
November). These three species alone endowed
nearly 32.7 per cent biomass in September, which
increased to 58.8 per cent in November (Table 20).
Though, Dichanthium annulatum recorded 37.5 per
cent increase during the study period, its biomass
contribution for the month of September was 8.2
per cent which, decreased to 6.5 per cent in
November. Further, the biomass production of
Dichanthium annulatum was found far lower than
Sporobolus sp., which was 62.6 per cent lower in
September and 82.1 per cent in November.

logopoides all other species showed a decrease,
while at site C except Chloris barbata, Cyperus
rotundas and Eragrostis sp. all other species
showed increasing trend. At site B, the Aeluropus
logopoides showed an increase of 44.7 per cent
during the study period, and contributed 17.8 per
cent of biomass in September, which further
increased to 46.9 per cent in November. The
biomass of highly palatable species such as
Dichanthium annulatum, Gandhiro was totally
grazed out and Sporobolus sp. was much reduced
at site B and C.
The comparison of biomass of different species
between September and November showed that
