In the cultivation of farm products, it is difficult to achieve target values for sugar content, etc. at the time of shipment. The cultivation assistance device is provided with: a growth data-setting means for selecting or generating a growth table comprising intermediate target values, which are determined from cultivation conditions including cultivation region, species, and shipment time as well as final target values, for multiple intermediate time points until shipment time and storing the table in a growth data-storing means; a growth data-storing means; a guidance content-storing means for storing guidance content corresponding to differences between the values measured for a crop, the cultivation of which is being assisted, and the intermediate target values; and a guidance content-selecting means for acquiring the values measured for the crop, the cultivation of which is being assisted, at each of multiple intermediate time points, comparing with the intermediate target values for said intermediate time points, and on the basis of the differences between the two, selecting and outputting guidance content from the guidance content-storing means.
