Fig. 5. Sequential removal of erroneous or uncertain yield data in the six screening steps: (1) header status up; (2) start-/end-pass delays; (3) grain flow, distance traveled, and grain moisture outliers; (4) minimum/maximum yield limits; (5) local neighborhood outliers; (6) short segments and co-located points. Values refer to irrigated and rainfed maize (Fields A and B, respectively) and irrigated and rainfed soybean (Fields C and D, respectively).
