Description Dry farming or dry land farming is a practice of growing a profitable crop without
irrigation in areas, which receive an annual rainfall of 500 mm or even less. India is
basically dependent on rain fed agriculture. About 44 per cent of total food production
comes from 67 per cent of total cultivated area, which is rain dependent. Dry lands
contribute more than 40 per cent food grains (80 per cent maize, 95 per cent of pearl millet
and sorghum). About 95 per cent of pulses and 75.5 per cent of oilseeds are also grown in
these areas. The mechanization of Indian agriculture has played dominant role in increasing
agricultural production, productivity and profitability by improving input use efficiency,
timely operation with precision, savings on labour, inputs, improving human comfort and
safety in operation etc.
Most of the farmers in India use traditional methods for planting such as broad
casting and seed dropping behind the plough. Traditional methods of crop planting have
involved planting of excess seed and increase human drudgery. Seed drills of different
types and capacities were developed and now being extensively used in the country for
sowing different kinds of seeds. Placement of seeds at correct depth is very important for
proper germination of seed especially under dry land farming, where soil moisture is at
greater depth.
Hence, an experiment on performance evaluation of tractor drawn seed drills with
different seed metering mechanisms suitable for ground nut, red gram and Bengal gram in
dry land was selected to study the performance parameters, modification of seed metering
mechanisms suitable for ground nut, red gram and Bengal gram and comparison of
economics of seed drills with different seed metering mechanisms. Five types of seed drills
were evaluated namely, 1) Ananta planter with inclined plate seed metering mechanism, 2)
Nandyala planter with horizontal plate seed metering mechanism, 3) Kisan automatic
planter with trough feed seed metering mechanism, 4) Gujrat seed cum fertilizer drill with
cup feed seed metering mechanism and 5) Local seed cum fertilizer with manual dropping
seed metering mechanism at Agricultural Research Station, Anantapur and farmers field.
The seed drills were calibrated in the laboratory at ARS, Anantapur as per BIS test
code IS 6316: 1993 for ground nut, red gram and Bengal gram. The existing seed metering
mechanisms were suitable for ground nut and Bengal gram which were not suitable for red
gram. Hence some modifications of seed metering mechanisms were needed to suite red
gram. Already available existing seed metering mechanisms were modified for red gram as
per requirement.
The highest field capacity was found to be 0.54 ha h-1, 0.47 ha h-1 and 0.54 ha h-1
for ground nut, Bengal gram and red gram crops with field efficiency of 71.9 per cent,
66.75 per cent and 74.15 per cent respectively for Ananta planter among all treated seed
drills whereas The lowest field capacity was found to be 0.43 ha h-1 for Local seed cum
fertilizer drill with field efficiency of 69.17 per cent for ground nut crop, 0.37 ha h-1 and
0.38 ha h-1 for Gujrat seed cum fertilizer drill with field efficiency of 64.11 per cent and
70.83 per cent for Bengal gram crop and red gram crop respectively among all seed drills.
The lowest seed rate obtained in the field was observed as 102.45 kg ha-1, 64.37 kg
ha1 and 34.65 kg ha-1 for ground nut, Bengal gram and red gram crops respectively for
Ananta planter among all seed drills. Whereas the highest seed rate was observed as 130.72
kg ha-1 and 79.15 kg ha-1 for ground nut and Bengal gram respectively for Local seed cum
fertilizer drill among all seed drills and 113.04 kg ha-1 for red gram crop for Nandyala
planter among all seed drills.
The highest pod /seed yield obtained for ground nut, Bengal gram and red gram
crop was found to be 1154.16 kg ha-1, 929.6 kg ha-1 and 2060 kg ha-1for Ananta planter
among all tested seed drills whereas the lowest pod/seed yield was found to be 895.83 kg
ha-1, 783.3 kg ha-1 and 1276 kg ha-1for ground nut, Bengal gram and red gram crop for
Gujrat seed cum fertilizer drill among all seed drills. This is due to the fact that the driving
wheel of Gujrat seed cum fertilizer drill was not rotated freely. Such that the seed and
halum yields are less for Gujrat seed cum fertilizer drill.
The highest net profit was found to be Rs. 45094 ha-1, Rs. 29798 ha-1 and Rs. 60339
ha-1 for ground nut, Bengal gram and red gram respectively for Ananta planter among all
tested seed drills whereas the lowest profit was found to be Rs. 28952 ha-1, Rs. 22568 ha-1
and Rs.32298 ha-1 for ground nut, Bengal gram and red gram respectively for Gujrat seed
cum fertilizer among all tested seed drills.
Finally it was observed that the Ananta planter performance was satisfactory for
groundnut, Bengal gram and red gram crops among all seed drills.
