In: Misr Journal of Agricultural Engineering 2005.v.22(2)Summary: The aim of study is to determine the optimum agro-technical aspects for precision planting of onion seeds to suit the condition of onion export. The studied treatments included: two ridgers with fixed and movable blades, two seed metering disks and four working forward speeds. Seeds used were for producing green onion with exportation specifications. The results generally showed that minimum values from plant spacing 1.4 cm, highest number of plants 70 plants/m, best diameter and length 1.96 and 27.4 cm were obtained under metering disk 144 holes and movable blade and forward speed 4.77km1h.. The power consumption and energy requirement increased with increasing forward speed and using ridger with fixed blade compared to movable blade. The highest marketing efficiency and maximum profitability were obtained when land leveling was done before planting with movable blade and using disk having 144 holes.
