India is the second largest producer of onion in the world next after China. Mechanization of farming is increasing day by day to produce yield of crop for gaining the profit. Mechanizination not only increases the production and productivity, but also reduces the labour cost and drudgery. As a result it produced more within the shortest possible period of time by using minimum manpower and improved cultural practices.
This present study is related to the development of an inclined plate metering device for planting onion bulb for the seed purpose and this metering device is applicable to meter a small onion bulb usually less than an inch in diameter which is used for propagation.
The main concept of design and development of onion bulb planter is metering device which is simple in their structure and easy to manufacture. In this study,three differentinclination angles of 500, 600 and 700evaluated for elevating error, cell fill and bulb damage at different peripheral speed and also evaluated the seed uniformity was describe by using the actual planting distance, mean plating distance, planting error and the quality of feed index at different travel speed under the laboratory and the precision in addition to the means and standard deviations of the sample method.
The result indicated that the elevating error was minimum at the inclination angle of 500 is 2.27 % at the peripheral speed of 7.6 m/min and maximum 10.82 % at the peripheral speed of 45.59 as compare to 600 and 700i.e. 2.28 to 11.63 and 4.95 to 13.77% at different peripheral speeds (7.6 to 45.59 m/min) it also indicate the peripheral speed increased the elevating error is also increase.
