Faruk Taser Oguz Tekelioglu 3200653The objective of this research was to evaluate the effects of different types of furrow opener and operation speed on soil properties, draft force and percentage of emerged tuber seedling. The experiment was conducted on a clay-silt textured soil using hoe, shoe and shovel type furrow openers with 2.02, 3.28 and 4.50 km h-1 operation speeds, respectively. After planting, soil penetration resistance, ridge height, mean emergence dates and percentage of emerged tuber seedling were determined. Soil penetration resistance increased with increasing operational speeds for each furrow opener type. The draft force requirement of furrow openers increased with operation speeds. Percentage of emerged tuber seedling was between 66.37 and 82.67%, based on furrow opener type and operational speeds. The lowest soil penetration resistance, draft force and high percentage of emerged tuber seedling occured found with shovel type furrow opener.]]>Al-Suhaibani, S.A. and A.
