tillage for preparing seedbed place, exterminaring weeds, putting in and fusing
plant’s residue to the land in order to find the land condition that needed by
root so it will increase air circulation, water infiltration, root growth and
take the nutrients by the root. The low productivity of alabio’s yam today
because the tillage is still traditional in planting, and no specially

tillage, (t1) minimum tillage, (t2) maximum tillage. Research result shows that
the tillage method given is significant to the plant’s height and the number of
leaves at the age of 14 and 21 DAP, significant to the rod’s diameter at the
age of 42 DAP and very significant to the plant’s height and the leaves at the
age of 28, 35 and 42 DAP, and no significant to the rod’s diameter at the age
of 14, 21, 28 and 35 DAP. Maximum tillage gives the best growth for alabio’s
