Banni Grassland
5.6.2.1 Biomass of Different Grass Species
Apart from Cyperus haspan, the biomass of six
common grass species of the site (Sporobolus sp.,
Aeluropus logopoides, Echinocloa sp., Cenchrus
sp., and Scirpus so.) was analysed. Excluding
Cyperus haspan, the biomass contribution of other
five species varied from 67.5 per cent of the mean
biomass production of vertical slopes to 35.2 per

cent of broad slopes (Table 13). Among the five
grass species, biomass of Aeluropus logopoides,
a saline tolerant species was found maximum in all
the sub-compartments except in ploughed and
broad slope areas. Ploughing and addition of
farmyard manure favoured the growth of
Sporobolus sp., where it contributed 41 per cent of
the biomass amongst the five species. In the broad
