Description 483-489
Precision sowing of a seed by a planter requires seed singulation by metering device and placement of that in soil.
Pneumatic planters are more popular among precision planters due to their obvious advantages. Design and operating
parameters of pneumatic planter needs to be optimized for getting the desired performance from the planter. A picking type
pneumatic metering mechanism was developed at CAET, AAU, Godhra, Gujarat, India. Response Surface Methodology
(RSM), a useful optimization technique, was used to optimized the operational parameters viz. forward speed &
vacuum pressure and design parameter-nozzle hole diameter of developed planter for radish. Experiments were planned
using Central Composite Design (CCD) and conducted in laboratory conditions for radish seeds. The independent
parameters chosen for the study were forward speed (0.14, 0.22, 0.33, 0.44 and 0.51 m/s), vacuum pressure (19.33, 29.32,
43.98, 58.64 and 68.63 kN/m2) and nozzle hole diameter (0.50, 0.75, 1.00, 1.25 and 1.50 mm) each with 5 levels. The effect
of independent parameters was observed by assessing the miss index, multiple index, quality of feed index, and precision.
The parameters under study were optimized based on values of miss index, multi index, quality feed index and precision in
spacing. It was found that among different variables nozzle hole diameter was most dominating. The optimum values
obtained for developed pneumatic planter were 0.23 m/s, 54.15 kN/m2 and 1.00 mm for forward speed, vacuum pressure,
and nozzle hole diameter, respectively for radish seeds. The study can be utilized for getting the optimum performance of
planter for different crops, which will not only help in precisely sowing of seeds, but also result in seed saving.
