In: Misr Journal of Agricultural Engineering 2005.v.22(2)Summary: The aim of the present study was to modify the feeding mechanism of the mechanical (Gaspardo) planter to become suitable for planting garlic cloves and test its performance. The performance of this planter with modified seed plates A and B were studied under four levels of planting forward speeds of 1.5, 2.5, 4.0 and 6.0 km/h and two levels of planter speed ratios of 0.6 and 0.8 with three levels of seed hopper capacity of 4.5, 2.25, and 1.125 kg. Manual planting of garlic was also studied and compared with mechanical planting method. The results indicated that the lowest value of longitudinal and transverse scattering of garlic was 0.69 cm and 0.92 cm obtained with plate A at seed hopper capacity of 4.5 kg and speed ratio of 0.6 with forward speed of 1.5 kmlh. The lowest value of missing hills was 3.75 % obtained at planting forward speed of 1.5 km/h. by using plate B. The beset results of planting uniformity, planting density, yield and appropriate levels of operation costs by using mechanical (Gaspardo) planter with modified cell plate A under limit of planting forward speed of 1.5 to 2.5 km/h and planter speed ratio of 0.6 and seed hopper capacity is more than 50% of its capacity. On the other hand results showed that manual planting of garlic did not achieve uniformity of growth and the yield was low.
