Description Mechanization requires appropriate machinery for ensuring timely field
operations, effective application of crop production inputs and reducing drudgery.
Agricultural productivity is linked with the availability of farm power. Bullocks meet
power requirements of marginal and small farms (less than 2 ha) with associated
limitation. Tractors meet requirement of large farms (above 6 ha). Power tillers are
visualized as appropriate source of farm power of medium farms (2-6 ha), where
India’s agricultural holdings pattern shows that 26% of area under cultivation is under
medium holdings of 2 to 6 ha.
Rice (Oryza Sativa) is a crop of paramount importance. It is one of the three
most important food crops in the world which forms the staple diet of 2.7 billion
people. The need of the hour is to reduce cost of cultivation and the production has to
be increased. Direct sowing of rice can eliminates seedbed preparation in a nursery,
pulling seedlings, hauling and transplanting operations. Total area under rice
cultivation in Andhra Pradesh is 42 million hectares.
Maize (Zea mays L.) is also one of the most important cereals of the world with
its world and provides more human food than any other cereals. India stands in the
fifth place where as with respect to production it ranks eleventh. Among the major
producing states Andhra Pradesh stand in first with contribution of 17% to total
Indian maize production (Maize out look report by KARVY). Maize cultivated area
in Andhra Pradesh in Kharif is 5.62 lakh hectares, in Rabi 2.48 lakh hectares during
2008-09.
In order to mechanize crop sowing operation, a suitable drill attachment for
power tiller is vital as it places the seed and fertilizer in the zone of adequate moisture
and at desired depth. The commercial available animal drawn seed cum fertilizer drill
was modified for sowing maize and paddy crops with power tiller. The over all
length of the Seed-cum-Fertilizer Drill was 1500 mm, width 700 mm and the height
was 900 mm. The diameter of the drive wheel was 550 mm. The drive to the seed
metering and the fertilizer metering can be obtained by shifting a dog clutch attached
to one of the ground wheel. The drive was provided to the metering mechanism was
through a sprocket and chain mechanism. The cell feed type metering mechanism
was used for sowing the seeds. The fertilizer will be metered with an agitator over an
orifice.
The effective field capacities of the power tiller drawn seed cum fertilizer drill
for maize and paddy crops were found to be 0.12 ha/h and 0.08 ha/h respectively.
Theoretical field capacities of the power tiller drawn seed cum fertilizer drill were
0.18 and 0.12 ha/h. The field efficiency of the machine for maize and paddy crops
was found to be 67%.
Grain yield of maize and paddy crop were 3626 kg/acre and 1.85 kg/acre. An
additional income of Rs. 5248.40/- and Rs. 2206.80/- was observed over bullock
drawn and tractor drawn implements in maize crop. In paddy an additional income of
Rs. 2524.16/- and 873.86/- was observed over bullock drawn and tractor drawn
implements with power tiller drawn seed cum fertilizer drill.
Key words: power tiller, maize, paddy, frame, ground wheel, cell feed type metering
mechanism, effective field capacity, theoretical field capacity, efficiency, grain yield,
production cost and net income.
