Food demand is foreseen to continue
increasing along with the increase
in the world population. However,
an expansion of cultivated acreage
can not be expected because of the
limitations arising from environment
conservation, especially, forest
conservation. Therefore, an improvement
in farm productivity has become
a necessary for coming days.
