The aim of this investigation is to design, develop and test a two rows garlic-cloves planter. The developed garlic-cloves planter consists of the tool bar, three hitching-points, frame, transmission system,furrow opener, covering device and two planting units. Each planting-unit consists of gloves hopper,agitator, cutoff, metering device, housing and metering device shaft. Laboratory experiments were carried out as a function of change in metering device speed, agitator speed, cutoff clearance and cloves size. The field experiments were conducted to optimize machine forward speed. The machine performance was studied in terms of cloves damage, plant scattering emergency, crop yield , specific energy and -planting cost. The experimental results reveal that the garlic-cloves planter is recommended to be used under the following conditions: Metering-device speed of 20 rpm (0.21 m/s) for all sizes of Chinese garlic-cloves. Agitator speed of 50 rpm (0.22 m/s) for all sizes of Chinese garlic-cloves. Cutoff clearance of 15 mm for all sizes of Chinese garlic-cloves. Planter forward speed of 3.44 km/h for the medium cloves.
