| Abstract | In Northern Thailand, farmers plant soybean in no-tillage
paddy field after rice harvest by the traditional method which
is a three person operation. The first person makes a hole,
the second person bends or squats to drop seeds in the hole
and the third person covers the hol e with soil, ashes or
animal manure. There are 3 main components; the double disk
furrow opener to open a V-shape furrow in a non-tilled field,
the seed metering roller which is a horizontal rotating
drilled shaft and the ash covering device fixed to the handle
of a 2- wheel tractor for ash feeding to cover seeds in the
furrow. After the prototype was produced, it was tested in a
non-tilled field after rice harvest. The field capacity of the
planter was 0.16 h a /hr and the field efficiency was 59%. Seed
damage rate by the planter was 7- 8%. The break even area for
planter compared with the traditional method was approximated
1.3 ha/yr. |
