Time to Finish Tillage Operation (\( T_o = \frac{A_f}{C_e \cdot N_I} \)):

Where:

• \( T_o \) is the time required to finish the tillage operation, in hours (hr).
• \( A_f \) is the area of the farm, in hectares.
• \( C_e \) is the effective field capacity, in hectares per hour (ha/hr).
• \( N_I \) is the number of tillage implements.
