by comparing the occurrence <strong>of</strong> Cyperus haspan<br />
in various sub-compartments between October and<br />
December. The contribution <strong>of</strong> Cyperus haspan<br />
decreased from 75 per cent in October to 45.6 per<br />
cent in December in the unploughed area while in<br />
the unprotected area it decreased from 83.4 to 74.9<br />
*data <strong>of</strong> November and December was compared<br />
per cent. A comparison <strong>of</strong> data during the same<br />
period in other sub-compartments showed that the<br />
percentage contribution <strong>of</strong> Cyperus haspan<br />
changed from 61.8 to 50.1 at ploughed area, 75.2 to<br />
19.4 at broad slopes, 54.9 to 12.5 at narrow vertical<br />
slopes and 56.6 to 34.7 at narrow horizontal slopes<br />
(Table 24).<br />
% are given in parenthesis Increase<br />
in other grass species<br />
(excluding Cyperus haspan)<br />
was recorded maximum at narrow<br />
vertical slopes (635.9 per<br />
cent), followed by broad slopes<br />
(363.2 per cent), narrow horizontal<br />
slopes (309.3 per cent),<br />
unploughed (164.8 per cent) and<br />
ploughed areas (64.4). In contrast<br />
to this, the outside area<br />
showed a decrease <strong>of</strong> 23.5 per<br />
cent.<br />
