A system operable to apply an agricultural input and harvesting an agricultural output in a management zone (216, 217, 218), the system comprising: a dispensing system operable to dispense the agricultural input; and a controller operatively connected to the dispensing system and configured to change the dispensement of the agricultural input from the dispensing system in a selected location within the management zone (216, 217, 218) and to replicate a rate of dispensement of the agricultural input in at least one additional location in the management zone (216, 217, 218); and a harvesting system operable to harvest the agricultural output and including a sensor operatively connected to the harvesting system and configured to record a yield data in order to associate the yield data with the actual location for the rate of dispensement of the agricultural input; wherein the selected location is a location that has been randomized within at least one predefined test plot (212, 212a-c) within the management zone (216, 217, 218), and wherein the rate of dispensement of the agricultural input is replicated in at least one additional location in the predefined test plot (212, 212a-c) of the management zone (216, 217, 218); characterized in that the system comprises system logic that is configured for identifying a machine including the dispensing system for providing agricultural input having at least one constraint required for input rate changes, and for determining a constraint required for a crop yield to pass the sensor of the harvesting system; and for incorporating the constraint into a determination of a minimum treatment area within the test plot (212, 212a-c) in order to account for the constraint while dispensing the agricultural input, wherein each location for each of the two or more treatment levels conforms to the constraint. a dispensing system operable to dispense the agricultural input; and a controller operatively connected to the dispensing system and configured to change the dispensement of the agricultural input from the dispensing system in a selected location within the management zone (216, 217, 218) and to replicate a rate of dispensement of the agricultural input in at least one additional location in the management zone (216, 217, 218); and a harvesting system operable to harvest the agricultural output and including a sensor operatively connected to the harvesting system and configured to record a yield data in order to associate the yield data with the actual location for the rate of dispensement of the agricultural input; wherein the selected location is a location that has been randomized within at least one predefined test plot (212, 212a-c) within the management zone (216, 217, 218), and wherein the rate of dispensement of the agricultural input is replicated in at least one additional location in the predefined test plot (212, 212a-c) of the management zone (216, 217, 218); characterized in that the system comprises system logic that is configured for identifying a machine including the dispensing system for providing agricultural input having at least one constraint required for input rate changes, and for determining a constraint required for a crop yield to pass the sensor of the harvesting system; and for incorporating the constraint into a determination of a minimum treatment area within the test plot (212, 212a-c) in order to account for the constraint while dispensing the agricultural input, wherein each location for each of the two or more treatment levels conforms to the constraint.
