Chloris barbata, Echinocloa sp., and<br />
Dichanthium annulatum increased tremendously<br />
in the ploughed area than the unploughed area<br />
(Table 21 and Figure 15).<br />
The increase in productivity <strong>of</strong> these species was;<br />
221 and 692 per cent for Cenchrus sp., 96 and 149<br />
per cent for Chloris barbata, 26.5 and 442 per cent<br />
for Echinocloa sp. and 23 and 60 per cent for<br />
Dichanthium annulatum. Contrary to this, increase<br />
in Sporobolus productivity was higher in<br />
unploughed area (216 per cent) than in ploughed<br />
area (104 percent). Table 21: Productivity (kg /<br />

5.6.2 Biomass Productivity at Bhirandiyara<br />
Site<br />
The biomass in the restoration site gradually<br />
increased from October to December; 1115.9<br />
kg/ha in October to 2228.7 kg/ha in December<br />
(Figure 16) and thus, showed an increase <strong>of</strong><br />
99.7 per cent whereas it decreased to 31.5 per<br />
cent in the unprotected area (Table 22). Among<br />
the five sub-compartments (unploughed, ploughed,<br />
broad slope -0.3m height x 5m wide, narrow vertical<br />
slope-0.5m height x 3m wide and narrow horizontal<br />
slope - 0.5m height x 3m wide) <strong>of</strong> the restoration<br />
site, narrow slopes showed a maximum increase <strong>of</strong><br />
biomass between October and December; 279.6 per<br />
cent in vertical slopes and 171.9 per cent in<br />
horizontal slopes. This was followed by<br />
unploughed area (112.8 per cent), broad slopes (42.9<br />
per cent) and ploughed area (25.9 per cent). This<br />
indicating clearly that the recovery <strong>of</strong> saline area in<br />
narrow steep slopes was faster. The biomass<br />
