Introduction
Conservation
agriculture (CA) based two wheel tractor (2WT) operated seeding
implements are becoming popular among farmers. About 700,000 2WT are
operating in Bangladesh. In Bangladesh, no-till seeder of 2WT was
first developed in WRC, BARI with FAO-CIMMYT supported programme
(2003-04). This seeder had no press wheel and limitation to bold size
seeds sowing. The no-till seeder was improved with ACIAR support with
the introduction of lighter weight toolbar frame, press wheel
attachment, seed and fertilizer box fixing over the handle bar of a
tractor for free flow of seeds to ground (Hossain et al., 2009). This
seeder performed better through crop residue but operators were
still not satisfied due to the height of seed box which blocked the
forward view of the field being seeded. Therefore, a user-friendly,
small 2WT no till seeder was developed capable of handling most seeds
and managing residue properly.
Materials
and methods
Two wheel
tractor operated no-till seeder is a pull type seeder and it has been
developed in BARI Rajshahi. The major components and specifications
are shown in Table 1. All accessories were set up under the handle
bar of the tractor. Field performance and adaptive trials were
conducted in the farmers’ fields by attaching a 12Hp Chinese
Dongfeng 2WT in North West drought prone area during 2011-14 for
wheat, mungbean, chickpea, maize and rice establishment (Fig.1).

Field
performances of the seeder were recorded as per Regional Network of
Agricultural Machinery (RNAM) Test Code. Cost was calculated
according to the farm machinery utilization method (Hunt, 1995).
Results
and Discussion
Field
performance of the no-till seeder for wheat, maize, mungbean,
chickpea establishment in several farmers’ field indicated that
crops can be established immediately after rice harvest using
residual soil moisture. There was enough ground clearance (45 cm)
between soil surface and toolbar frame. Furrow opener layout
facilitated crop residue passage without blockage. Row positions can
be adjusted sliding the clamp of tynes on the toolbar frame.
Effective field capacity of the seeder was 0.12 ha/hr. Seeding with 4
tynes was more appropriate for soft to medium hard soil and 3 tynes
for hard soils. The inclined plate seed metering device performed
satisfactorily with small to large seeds (Table 2). The seeder was
tested in a wheat-mungbean-rice crop rotation lasting 4 years at
Rajshahi where the soil type is dominantly silty clay loam. Rice was
seeded directly in unploughed/unpuddled soil. There were no
significant yield variations between no-till and conventional method
(Table 3). Weed management in no-till rice cultivation is still
challenging to convince traditional rice farmers.

Planting cost and break-even point used for no-till seeder was
calculated on the basis of fixed cost and variable cost. There were
significant cost differences between no-till and conventional
practice (Table 4). Break-even point of no till seeder was 4.0 ha.

The 2WT
(9Kw) no-till seeder can pull 4 tynes in soft to medium hard soil but
3 tynes in hard soil and it was capable of seeding through heavy rice
and wheat residue (1.5 - 2.4 t/ha) without blockages as there are
sufficient clearance between toolbar frame and ground surface. The
seeder is low cost (US$ 350-400; without power unit), light in weight
and local manufacturer can fabricate complete set of no-till seeder
within a short period of time. The no-till seeder can be used in
other Asian countries where the 2WT is the common farming equipment.
