Threshing Efficiency (\( \xi_t = \frac{(W_c + L_b + L_s + L_{sc}) \times 100}{W_c + L_b + L_s + L_u + L_{sc}} \)):

Where:

• \( \xi_t \) is the threshing efficiency, in %.
• \( W_c \) is the weight of clean threshed grain, in kg.
• \( L_b \) is the blower loss, in kg.
• \( L_s \) is the separation loss, in kg.
• \( L_{sc} \) is the scattering loss, in kg.
• \( L_u \) is the unthreshed loss, in kg.
