Delivery Rate (\( Q \)):

\[ Q = \frac{L \times 10000}{v \times t \times W} \]

Where:

• \( Q \) is the delivery rate, in kg/ha.
• \( L \) is the delivery for a given \( N \), in kg.
• \( v \) is the tractor speed, in meters per second (m/s).
• \( t \) is the time for measuring delivery, in seconds (s).
• \( W \) is the working width, in meters (m).
