System validation
The system validity was tested for the five implements to compare between actual and predicted effective field capacity (ha/h), implements width (m) and fuel consumption (L/h) as shown in Table 2. The root mean square of the error criterion was used as a comparison measure. The results showed very low RMSE (0.179), (1.095), and (0.1612) between the predicted and actual data for effective capacity, implements width (m) and fuel consumption (L/h), respectively (Table 2). Moreover, Paired T-test indicates no significant difference (at 5%) between the system predictions and actual data (Table 3). These indicate a high consistency between actual data and the system predictions.
