Abstract: An actual measurement value calculation unit of a growth information providing apparatus calculates an actual measurement value representing a growth situation of a crop in a farm field. An acquisition unit acquires weather information in the farm field where the crop is planted. A trial calculation unit calculates a trial calculation growth curve representing the transition of the growth situation in calculation by making a trial calculation of the transition of the growth situation of the crop toward the target yield using the environment information including the weather information after the crop is planted in the farm field and the information about the target yield of the crop. A display control unit performs display control of displaying both the actual measurement value of the growth situation of the crop and the trial calculation growth curve.
