Estimation of crown biomass production of Poplus nigra Italica Muench in Pakistan
*Muhammad Iqbal, James A. Moore and ***Charles R. Hatch
ABSTRACT
In areas where Lombardy (populusnigra Italica Muench)
grows in Pakistan crown biomasss is lopped at various
intensities and the woody branches and foliage
components are used as fuel wood and fodder. The
objective of this study was to developed simple and
practical prediction models using linear regression to
estimate crown biomass. Models were developed for green
and air-dried branch wood and fodder crown biomass
components under different lopping intensities. Tables
were produced to formulate management, planning and
marketing strategies. Diameter at breast height squared
(Dbh2) and its square proved to be the independent
variables to predict crown biomass weights.
