Description 1033-1041
The main challenge with conservation tillage methods, such as no-tillage and minimum tillage planting is placing seeds
beneath crop residue with proper seed-soil contact. Sowing technologies in conservation tillage can improve soil quality,
reduce erosion, and save time and fuel. However, crop seed germination is negatively affected by plant residues on the soil
surface, so these residues must be managed. To overcome this problem, three types of coulter blades were tested in a soil bin
to assess their ability to cut paddy residue, considering factors such as speed ratio and the number of press wheels.
Horizontal and vertical forces, torque applied, and power requirements were calculated for selected blades at different speed
ratios, numbers of press wheels, and different levels of rice residue during operations. Various parameters, such as the type
of cutting coulter blades, speed ratio, number of press wheels, and different levels of rice residue density, were optimized to
achieve maximum paddy residue cutting efficiency and minimum straw clogging. The optimized values of horizontal force
(12.88 kg), vertical force (33.45 kg), torque applied (12.48 Nm), and power requirement (310.6 W) were obtained at the
optimal design parameters: speed ratio (7.70), number of press wheels (2), and straw density (500 kg/ha). The maximum
cutting efficiency of 100% and the minimum straw clogging of 1.80 kg/ha were achieved for a plain coulter blade.
