To provide a yield prediction system capable of accurately predicting a yield of a plant.SOLUTION: A yield prediction system 8 is configured to set an input cultivation environment parameter for each cultivation region, control a cultivation environment of plants for each cultivation region based on the input cultivation environment parameter, measure an output cultivation environment parameter for each cultivation region, record the output cultivation environment parameter, measure a weight of the harvested plants, record the weight, select one or two or more parameters used for prediction of yield for each input cultivation environment parameter out of the output cultivation environment parameters, then, based on a parameter selected and related to the plants which are being cultivated out of the output cultivation environment parameter, a parameter selected and related to plants which were cultivated past out of the output cultivation environment parameter, and the recorded weight of the plants, estimate the yield.SELECTED DRAWING: Figure 3
