Abstract
The effect of aspect and distance from the base of scattered trees of Dalbergia sissoo and Acacia nilotica were studied in Bahawalpur district of southern Punjab. Four transects of 20m length were laid in north, east, south and western directions. Measurement of cotton yield was made by 2m2 quadrat at 1, 4, 7, 10 and 20m distances. Cotton yield increased significantly with increase in distance from both D. sissoo and A. nilotica. Southern aspect had higher cotton yield under D. sissoo but there was no effect of aspect under A. nilotica. Timely pruning of both the species might reduce the loss in cotton yield. Key words: Acacia nilotica; Dalbergia sissoo; cotton yield
