ABSTRACT
A study was carried out in village Satrah. District
Sialkot to determine the effect of Shisham (Dalbergia
sissoo) on the yield of wheat crop. Fifty trees of
variable diameter and heights were selected for southern
side of the field and were divided into seven diameter
classes e.g.15 - 19.9, 20 - 24, 9, 25 - 29.9, 30, 34.9 cms,
35 - 39.9, 40 - 44.9 and 45 - 50 cms. Dalbergia sissoo trees
affected crop height up to a distance of 11.0 meters but
the effect was statistically non-significant. On the
other hand both the biomass and grain yield was
significantly affected up to a distance of 8.5 meters.
