In order to provide a farming schedule matching a growing environment for crops and increase reliability of farming support, the present invention comprises: an indicator value calculation unit that calculates indicator values at which the growth of crops is hindered, during a period including at least an observation period in which the effects of farming work performed in order to grow crops are observed; and a schedule generation unit that, in order to reduce the indicator values calculated by the indicator value calculation unit, generates a schedule for farming work performed on crops during a prescribed farming period being a period prior to the observation period.
