Provided is a crop cultivation system whereby the amount of irrigation water such as a nutrient solution can be appropriately controlled. This crop cultivation system comprises a cultivation bed, a waterproof sheet, a cultivation medium, a panel for settled planting, an irrigation tube and an irrigation control means. In the cultivation bed, areas wherein crops are to be settled in a field are defined by frames. The waterproof sheet is provided so as to cover the areas and frames. The cultivation medium is disposed on the waterproof sheet in the areas and the crops are settled therein. In the panel for settled planting, said panel being provided so as to cover the cultivation medium, through holes defining the settled plating positions of the respective crops are formed. The irrigation tube is connected to a supply system for supplying a nutrient solution, which is prepared by diluting a fertilizer, and water and extends over the panel for settled planting. From the irrigation tube, the nutrient solution and water are irrigated to the cultivation medium through the through holes. The irrigation control means controls, on the basis of measured insolation value, the amount of the nutrient solution or water to be supplied from the supply system to the irrigation tube.
