【 摘 要 】

This research aimed to study the physical properties and pattern of cassava bunches in soil as data for inter-row weeding machine design. The study consisted of the bunch weight, bunch size, and spreading pattern of bunch. The 3 - 12 months old Huay-Bong variety was investigated monthly. The results showed that at 3 months old the cassava had a bunch weight, cassava root diameter, and bunch spreading perpendicular to row of 0.4 - 1.0 kg, 1.1 - 3.1 centimetres, and 34.0 - 98.0 centimetres respectively. At the harvesting period the bunch weight was 1.8 - 6.1 kg with cassava root diameter of 3.0 - 8.0 centimetres, while the spreading of bunch perpendicular to row on each side was 10.0 - 50.0 centimetres, and row distance was 19.0 - 110.0 centimetres. Finally the average of depth of bunch was 24.5 - 33.1 centimetres respectively.
