Effect of improvement practices on Dalbergia sissoo (Shisham) planted in Islamabad
M.I. Sheikh and Abdul Aleem
ABSTRACT
Dalbargia sissoo (shisham) is one of the most profusely
planted trees in Islamabad. Yellowing of its foliage and
subsequent death caused considerable alarm in the
nation's capital. A study was started in 16 and 6 year
old blocks to find out if irrigation, spray with
dieldrin and use of N.P. could improve the situation.
The study was maintained for five years and was assessed
recently. It was found that fertilizers improved the
growth of 16 year old plants and hence resistance to the
disease but none of the three treatments had any effect
on the younger plants.
