[0038] The defective rice ratio calculation unit 38 calculates the defective rice ratio R for each field. The defective rice ratio R is the ratio of defective rice in the yield of the harvested product. The defective rice ratio calculation unit 38 can calculate the defective rice ratio R, for example, by the following formula. R = W6 / Y Here, R: defective rice ratio, W6: weight of defective rice, Y: yield of harvested product The defective rice ratio R calculated by the defective rice ratio calculation unit 38 will be stored in the storage unit 36.

[0039] The storage time calculation unit 39 calculates the storage time T3 of the harvested product for each field. The storage time calculation unit 39 can calculate the storage time T3, for example, by the following formula. T3 = T2 - T1 Here, T1: loading time, T2: drying start time, T3: storage time The standing time T3 calculated by the standing time calculation unit 39 will be stored in the storage unit 36.

[0040] The harvested product evaluation unit 41 evaluates the harvested products for each field based on the adjustment information I1 of the plurality of types of adjustment machines 4 and the harvested product information I2. In the present embodiment, the harvested product evaluation unit 41 evaluates the quality of the harvested products for each field and evaluates the composition of the harvested products for each field based on the adjustment information I1 of the plurality of types of adjustment machines 4 and the harvested product information I2. The evaluation result E of the harvested products by the harvested product evaluation unit 41 will be stored in the storage unit 36.

[0041] The harvested product evaluation unit 41 evaluates the quality of the harvested products for each field based on the moisture value M1 of the harvested products (paddy), the broken rice ratio R, the moisture value M2 of the grains at the end of drying in the dryer 5, the standing time T3, and the scorching hit rate H. Specifically, the harvested product evaluation unit 41 evaluates the quality of the harvested products for each field as follows. (1) When at least one of whether the moisture value M1 of the harvested products (paddy) has increased compared to the previous year or whether the broken rice ratio R has increased compared to the previous year applies, the harvested products of the field are evaluated as "immature rice". (2) When the moisture value M2 of the grains at the end of drying in the dryer 5 has decreased compared to the previous year, the harvested products of the field are evaluated as "over-dried". (3) When at least one of whether the standing time T3 has increased compared to the previous year or whether the scorching hit rate H has increased compared to the previous year applies, the harvested products of the field are evaluated as "over-standing".

[0042] Here, as shown in FIG. 4, the composition of the harvested products (paddy) in the field can be classified into, for example, moisture, husk, broken rice, colored debris, and brown rice. The combination of moisture, husk, broken rice, colored debris, and brown rice is called paddy, the combination of husk, broken rice, colored debris, and brown rice is called dried paddy, and the combination of broken rice, colored debris, and brown rice can be called rough brown rice.

[0043] As shown in FIG. 3, the harvested product evaluation unit 41 calculates the proportions of moisture, husk, broken rice, colored rice bran, and polished brown rice as the composition of the harvested product.

[0044] The harvested product evaluation unit 41 calculates the weight W4 of moisture based on the weight W1 of paddy rice and the weight W2 of dried paddy rice. The harvested product evaluation unit 41 can calculate the weight W4 of moisture, for example, by the following formula. W4 = W1 - W2 Here, W1: weight of paddy rice, W2: weight of dried paddy rice, W4: weight of moisture

[0045] The weight W2 of dried paddy rice is the weight of the grains at the end of drying in the dryer 5. The harvested product evaluation unit 41 can calculate the weight W2 of dried paddy rice, for example, by the following formula. W2 = (W1 - W1×M1 / 100) / (1 - MT / 100) Here, M1: moisture content of paddy rice, MT: target moisture content of the dryer 5, W1: weight of paddy rice, W2: weight of dried paddy rice

The harvested product evaluation unit 41 can calculate the weight W5 of husk, for example, by the following formula. W5 = W1 - (W4 + W6 + W7 + W8) Here, W1: weight of paddy rice, W4: weight of moisture, W5: weight of husk, W6: weight of broken rice, W7: weight of colored rice bran, W8: weight of polished brown rice

[0047] The sales calculation unit 44 acquires the yield Y of the harvested product in the field, and calculates the sales S of the harvested product 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 product, for example, by the following formula. S = W8×U Here, S: sales, U: unit price of the harvested product, W8: weight W8 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 storage unit 36. The sales S calculated by the sales calculation unit 44 will be stored in the storage unit 36.

[0048] The sales information generation unit 45 calls the yield Y and the sales S from the storage unit 36 and generates sales information I3, which is information indicating the relationship between the yield Y and the sales S in the field.
