Growth development and nutrient studies of sugar cane in Uganda
Abstract
The
objective
of
the
project
was
to
investi
g
ate
the
growth
development
pattern
of
sugar
cane
as
infl
ue
nced
by
age
and
the
env.ironmental
conditions
prevailin
g
in
the
main
sugar
cane
growing
areas
of
Uganda,
so
as
t

as
a
guide
to
improved
field
husbandry
practices.
A

The
