The broken rice ratio calculation unit 38 calculates the broken rice ratio R for each field. The broken rice ratio R is the proportion of broken rice in the yield of the harvested product. The broken rice ratio calculation unit 38 can calculate the broken rice ratio R, for example, using the following formula.
R = W6/Y
Here, R: broken rice ratio, W6: weight of broken rice, Y: yield of harvested product. The broken rice ratio R calculated by the broken rice ratio calculation unit 38 is stored in the memory unit 36.

The leaving time calculation unit 39 calculates the leaving time T3 of the harvested products for each field. The leaving time calculation unit 39 can calculate the leaving time T3, for example, using the following formula.
T3 = T2 - T1
Here, T1 is the receiving time, T2 is the drying start time, and T3 is the leaving time. The leaving time T3 calculated by the leaving time calculation unit 39 is stored in the memory unit 36.

The harvest evaluation unit 41 evaluates the harvest for each field based on the adjustment information I1 and harvest information I2 from the multiple types of adjustment machines 4. In this embodiment, the harvest evaluation unit 41 evaluates the quality of the harvest for each field based on the adjustment information I1 and harvest information I2 from the multiple types of adjustment machines 4, and evaluates the composition of the harvest for each field. The harvest evaluation results E by the harvest evaluation unit 41 are stored in the memory unit 36.

The harvest evaluation unit 41 evaluates the quality of the harvest for each field based on the moisture value M1 of the harvest (raw rice), the broken rice ratio R, the moisture value M2 of the grain when finished drying in the dryer 5, the leaving time T3, and the burnt hit rate H.
Specifically, the harvest evaluation unit 41 evaluates the quality of the harvest for each field as follows.
(1) The harvest evaluation unit 41 evaluates the harvest in the field as “immature rice” if at least one of the following conditions is met: the moisture content M1 of the harvest (raw rice) has increased compared to the previous year; or the broken rice ratio R has increased compared to the previous year.
(2) If the moisture content M2 of the grain at the time of drying completion in the dryer 5 is lower than that of the previous year, the harvest evaluation unit 41 evaluates the harvest in the field as being "over-dried."
(3) The harvest evaluation unit 41 evaluates the harvest in the field as being “excessively neglected” if at least one of the following conditions is met: the abandoned time T3 has increased compared to the previous year, or the burnt hit rate H has increased compared to the previous year.

As shown in Figure 4, the composition of the harvested product (raw rice) in the field can be divided into, for example, moisture, rice husks, broken rice, discolored scraps, and polished brown rice. The combination of moisture, rice husks, broken rice, discolored scraps, and polished brown rice is called raw rice, the combination of rice husks, broken rice, discolored scraps, and polished brown rice is called dried rice, and the combination of broken rice, discolored scraps, and polished brown rice can be called rough brown rice.

As shown in Figure 3, the harvest evaluation unit 41 calculates the proportions of moisture, rice husks, broken rice, brown rice, and polished brown rice as the composition of the harvest.

The harvest product evaluation unit 41 calculates the weight W4 of water based on the weight W1 of the raw rice and the weight W2 of the dried rice. The harvest product evaluation unit 41 can calculate the weight W4 of water, for example, using the following formula.
W4 = W1 - W2
Where W1: weight of raw rice, W2: weight of dried rice, W4: weight of water

The weight W2 of the dried unhulled grains is the weight of the grains when they are finished drying in the dryer 5. The harvest evaluation unit 41 can calculate the weight W2 of the dried unhulled grains, for example, using the following formula.
W2=(W1-W1×M1/100)/(1-MT/100)
where M1 is the moisture value of raw rice, MT is the target moisture value of the dryer 5, W1 is the weight of raw rice, and W2 is the weight of dried rice.

The harvest product evaluation unit 41 calculates the weight W5 of the rice husks based on the weight W1 of the raw rice, the weight W4 of the water, the weight W6 of the broken rice, the weight W7 of the brown rice, and the weight W8 of the polished brown rice. The harvest product evaluation unit 41 can calculate the weight W5 of the rice husks, for example, using the following formula.
W5=W1-(W4+W6+W7+W8)
Here, W1: weight of raw rice, W4: weight of water, W5: weight of rice husk, W6: weight of broken rice, W7: weight of brown rice, W8: weight of polished brown rice

The sales calculation unit 44 acquires the yield Y of the harvested crops in the field, and calculates the sales S of the harvested crops for the yield Y in the field based on the yield Y and the adjustment information I1. The sales calculation unit 44 can calculate the sales S of the harvested crops, for example, using the following formula.
S = W8 x U
Where S: sales, U: unit price of harvested product, W8: weight of polished brown rice
The weight W8 of the polished brown rice is synonymous with the weighing result of the weighing machine 9. The unit price U of the harvested product is stored in the memory unit 36. The sales S calculated by the sales calculation unit 44 is stored in the memory unit 36.

The sales information generation unit 45 retrieves the yield Y and sales S from the memory unit 36 and generates sales information I3, which is information indicating the relationship between the yield Y and sales S in the field. The sales information I3 generated by the sales information generation unit 45 is stored in the memory unit 36.

The display data generation unit 43 retrieves the evaluation result E from the storage unit 36 and generates evaluation result display data D1 for displaying the evaluation result E on the display unit 2A of the user terminal 2. The evaluation result display data D1 generated by the display data generation unit 43 is stored in the storage unit 36. The display data generation unit 43 retrieves the sales information I3 from the storage unit 36 and generates sales information display data D2 for displaying the sales information I3 on the display unit 2A of the user terminal 2. The sales information display data D2 generated by the display data generation unit 43 is stored in the storage unit 36.

In response to a request from the user terminal 2, the transmission unit 42 retrieves the evaluation result display data D1 and the field map MA from the memory unit 36 and transmits the evaluation result display data D1 and the field map MA to the user terminal 2. The evaluation result display data D1 and the field map MA transmitted from the transmission unit 42 are displayed on the display unit 2A of the user terminal 2 (see Figures 5 and 6). The request from the user terminal 2 is made by the user via the input unit 2B of the user terminal 2.

In response to a request from the user terminal 2, the transmission unit 42 retrieves the sales information display data D2 and the field map MA from the storage unit 36 and transmits the sales information display data D2 and the field map MA to the user terminal 2. The sales information display data D2 and the field map MA transmitted from the transmission unit 42 are displayed on the display unit 2A of the user terminal 2 (see Figure 7). The request from the user terminal 2 is made by the user via the input unit 2B of the user terminal 2.

Figure 5 shows an example of a screen displaying evaluation result display data D1 related to harvest quality and a field map MA on the display unit 2A of the user terminal 2. As shown in Figure 5, when a user selects field F1 on the field map MA on the display unit 2A of the user terminal 2, the fact that the harvest quality of field F1 is "unripe" is displayed on the field map MA on the display unit 2A of the user terminal 2 using text TE1 and illustration IL1. That is, the evaluation result display data D1 includes text TE1 and illustration IL1. The text TE1 and illustration IL1 are displayed using pop-ups. The text TE1 includes the following text: "Possible immature rice," "Harvest (raw rice) moisture value: XX%," and "Raw rice fraction: Increased compared to the previous year." The illustration IL1 is an illustration of unripe grains. Field F1 is colored in the color corresponding to "unripe," distinguishing it from the other fields.

When the user selects field F2 on the field map MA on the display unit 2A of the user terminal 2, the fact that the quality of the harvested product in field F2 is "too dry" is displayed by text TE2 and illustration IL2 on the field map MA on the display unit 2A of the user terminal 2. In other words, the evaluation result display data D1 includes the text TE2 and the illustration IL2.
Text TE2 and illustration IL2 are displayed by a pop-up. Text TE2 includes the text "Possible over-drying" and "Finishing moisture value: Decreased compared to the previous year.""Finishing moisture value" refers to the moisture value of the grain at the time of finishing drying in the dryer 5. Illustration IL2 is an illustration of over-dried grain. Field F2 is colored in the color corresponding to "over-drying" and is color-coded from the other fields.

When the user selects field F3 on the field map MA on the display unit 2A of the user terminal 2, the fact that the quality of the harvest in field F3 is "excessively neglected" is displayed on the field map MA on the display unit 2A of the user terminal 2 by means of text TE3 and illustration IL3. That is, the evaluation result display data D1 includes text TE3 and illustration IL3. Text TE3 and illustration IL3 are displayed by pop-up. Text TE3 includes the text "Possible excessive neglect," "Abandonment time: increased compared to previous year," and "Scorched hit rate: increased compared to previous year." Illustration IL3 is an illustration of over-neglected grain. Field F3 is colored in the color corresponding to "excessively neglected," and is color-coded from the other fields.

Figure 6 shows an example of a screen on the display unit 2A of the user terminal 2, where evaluation result display data D1 regarding the composition of the harvested crop and a field map MA are displayed. As shown in Figure 6, when the user selects field F4 on the field map MA on the display unit 2A of the user terminal 2, the composition of the harvested crop in field F4 is displayed in graph GR1 on the field map MA on the display unit 2A of the user terminal 2. In other words, the evaluation result display data D1 includes graph GR1. Graph GR1 is displayed as a pop-up.

In the example shown in FIG. 6, graph GR1 is a bar graph. The horizontal axis of graph GR1 represents the composition of the harvest (moisture, rice husks, broken rice, brown rice, and polished brown rice). The vertical axis of graph GR1 represents the proportion of the composition of the harvest. Graph GR1 displays the composition of the harvest for two years (this year and last year). In other words, evaluation result display data D1 relating to the composition of the harvest for each year for multiple years (two years in this embodiment) is displayed on the display unit 2A of the user terminal 2.

Figure 7 shows an example of a screen on which sales information display data D2 and a field map MA are displayed on the display unit 2A of the user terminal 2. As shown in Figure 7, when a user selects field F4 on the field map MA on the display unit 2A of the user terminal 2, the relationship between yield Y and sales S for field F4 is displayed in the form of graph GR2 on the field map MA on the display unit 2A of the user terminal 2. In other words, the sales information display data D2 includes graph GR2. Graph GR2 is displayed as a pop-up.

In the example shown in FIG. 7, graph GR2 is a scatter plot. The horizontal axis of graph GR2 represents yield Y. The vertical axis of graph GR2 represents sales S. Graph GR2 displays the relationship between yield Y and sales S for two years (this year and last year). In other words, sales information display data D2 for each year is displayed on the display unit 2A of the user terminal 2 for multiple years (two years in this embodiment).

As shown in FIG. 8 , the parameter acquisition unit 46 acquires an adjustment machine parameter P, which is a parameter of the adjustment machine 4, in association with the field where the crop to be adjusted by the adjustment machine 4 was harvested. In this embodiment, the parameter acquisition unit 46 acquires a dryer parameter P1, which is a parameter of the dryer 5, from the dryer 5 (control device 29) in association with the field where the grain to be dried by the dryer 5 was harvested, and acquires a color sorter parameter P2, which is a parameter of the color sorter 8, from the color sorter 8 (control device 32) in association with the field where the grain to be color sorted by the color sorter 8 was harvested. In other words, the parameter acquisition unit 46 can acquire multiple types (two types in this embodiment) of adjustment machine parameters P (dryer parameter P1 and color sorter parameter P2). The dryer parameter P1 and color sorter parameter P2 acquired by the parameter acquisition unit 46 are stored in the memory unit 36.

Dryer parameters P1 are parameters used to configure various settings for the dryer 5. For example, dryer parameters P1 include a target moisture value, which is the target moisture value for drying grains.

The color sorter parameters P2 are parameters for configuring various settings for the color sorter 8. For example, the color sorter parameters P2 include parameters for adjusting the sensitivity of color sorting (e.g., sensitivity adjustment parameters such as reflected light reference values and transmitted light reference values).

The field selection receiving unit 47 receives the selection of a field by the user terminal 2. The selection of a field by the user terminal 2 is performed by the user on the field map MA on the display unit 2A of the user terminal 2 using the input unit 2B of the user terminal 2. When the user selects a field on the field map MA on the display unit 2A of the user terminal 2 using the input unit 2B of the user terminal 2, the field selection receiving unit 47 receives the selection of the field by the user terminal 2. In this embodiment, the field selection receiving unit 47 receives the selection of the first field F1 and the second field F5 by the user terminal 2.

In response to a request from the user terminal 2, the parameter association unit 48 associates the adjuster parameter P corresponding to the first field F1 accepted by the field selection acceptance unit 47 with the second field F5 accepted by the field selection acceptance unit 47. Here, the memory unit 36 stores the dryer parameter P1 and the color sorter parameter P2 as the adjuster parameter P corresponding to the first field F1. In this case, the parameter association unit 48 associates the dryer parameter P1 and the color sorter parameter P2 with the second field F5 in response to a request from the user terminal 2.
