Sr. No. Variables Levels
1 Inclination of seed box 50 and 60 degree
2 Size of cells
1. Maximum seed dimension
2. 5 per cent more than maximum seed dimensions
3. 10 per cent more than maximum seed dimensions
4. 20 per cent more than maximum seed dimensions
The field trial was carried out at travel speed 4.5 km/h and with seed metering mechanism to
observe the effect of cell size and inclination of plate.
Results
The construction of the machine was made sturdy and weight was kept matching to the pulling
capacity of Tractor above 35hp. The total weight of the developed intercrop planter was 270
kg. The unit price of developed planter was ₹ 56,500 /-.
Based on the result of experiments of the study the following conclusions were drawn
1. The intercrop planter was designed on the basis of agronomical crop practices and
physical parameters namely length, width, thickness, bulk density, angle of repose,
geometric mean diameter of castor and green gram.
2. In calibration of intercrop planter, the desired seed rate obtained of castor and green
gram were 4.73 kg/ha and 13.19 kg/ha at combination of 60˚ angle of inclination and
13 mm and 6 mm size of cells, respectively.
3. The developed intercrop planter was evaluated with castor and green gram in
intercropping. The results shown that combination of 60˚ inclination angle and
maximum seed size of metering plate was gave better results during the laboratory
evaluation.
4. 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 4.73 kg/ha, 60.04 cm, 1.60 per cent, 0.00
