wheat = 5625 kg ha -l) show that the extraction at these distances, respec-
tively are entirely due to eucalyptus and adjoining crop. Distinctly different
percentage moisture extraction pattern obtained at 1 and 9 m distances
verifies this observation in Table 3. Percent moisture extraction from a given
layer, PME is defined as the ratio of moisture depleted in 14 days to the total
moisture present in it on 22.1.88. On an average, PME below 60cm soil
depth was 43% at 1 m distance and 4% at 9 m distance (Table 3). Forty two
per cent moisture extraction from 120-150 cm depth at 1 m distance further
indicated that eucalyptus drew considerable water even from depths greater
than 150 cm. It evidently suggests that eucalyptus plants behave like a water
depleting pump and its plantation may be recommended for areas having
high water table conditions. Moisture extraction from 0-150 cm at 1 and 9 m
distances was estimated as 15cm and 2.9cm, respectively (Fig. 2a). It
evidently showed that eucalyptus extracted about 5 times more water as
compared to mustard crop from 0-150cm profile. Langford et al. [1982],
Mackay and Cornish [1982] and Pilgrim et al. [1982] had reported that clear
felling of the forests can resut in immediate increase in stream flow upto a
factor of 3.
