概要

• 論文の詳細を見る

• Incorrect seeding depth causes poor seed germination, low seedling emergence and poor crop yields. To address this, a control system employing a unique method of regulating seeding depth via an independent furrow opener was designed and built. This study evaluates the performance of this system. Actual soybean seeding showed significant differences in seeding depth between the controlled and uncontrolled rows in the zero tillage treatments and conventional tillage treatments where the plow and rotary tiller were used. The control system effectively placed seeds at the correct depth and seedling emergence was positively improved.
