In order to give an idea of the extent of damage a row of plantation does
on adjoining agricultural crops, the percentage yield reductions, YR are
calculated as a function of distance by comparing these yields to the yields
obtained at the centre of the fields (mustard = 1650kgha-1,
wheat = 5625 kg ha-l). Yield reductions data given in Table 4 thus show
that yield reductions are higher in mustard (low water requiring crop, 2
irrigations) than in wheat (high water requiring crop, 5 irrigations). On an
average these were 47 and 34%, respectively in the 10 m strip on both sides
of the plantation. The average reduction for the two crops comes to 41%
(Table 4). The results may be seen as having practical relevance in that if one
