per cent and 98.40 per cent for castor and 13.19 kg/ha, 9.72 cm, 0.00 per cent, 0.00 per
cent and 98.00 per cent for green gram, respectively during laboratory evaluation.
5. The results shown that combination of 60˚ inclination angle and maximum seed size of
metering plate was gave better results during the field evaluation.
6. At consummated combination of inclination angle and size of cells, the corresponding
dependent variable such as seed rate, average seed spacing, missing index, multiple
index and quality of feed index found were 60.26 cm, 10.40 per cent, 0.00 per cent and
89.60 per cent for castor and 9.95 cm, 8.00 per cent, 0.00 per cent and 92.00 per cent
for green gram, respectively during field evaluation.
7. Depth of sowing, speed of operation, draft, theoretical capacity, effective capacity, field
efficiency, field machine index and fuel consumption were obtained 5 cm for castor,
3.5 cm for green gram, 4.5 km/h, 233 kgf, 0.90 ha/h, 0.79 ha/h, 84.43 per cent, 87.77
per cent and 3.61 l/h, respectively.
8. Cost of operation, breakeven point and payback period of intercrop planter were
Conclusions
obtained ₹ 608 per hour (₹ 770 per ha), 18.90 h/annum and 2.06 year, respectively.
Inclination angle of metering plate 60˚ and maximum seed size of metering plate was giving
better results during the field evaluation. Developed planter saving in time and cost of planting
compared with conventional method were 92.25 and 46.15 %, respectively.
