PROBLEM TO BE SOLVED: To provide a method for tomato cultivation, with which reduction in quality caused by excessive application of water and fertilizer for maintenance of growing power (securement of yield) of tomato is prevented, defective fruiting of flower and scorch of fruit occurring in a high-temperature period in the summer are prevented and reduction in shipment and qualities is prevented. SOLUTION: In this method for plant cultivation in which (1) a medium having no fertility of soil is isolated from rainwater and ground, (2) a crop plant is germinated and transplanted, (3) supply of water and a nitrogen fertilizer to the crop plant is stopped after the germination or transplantation, (4) water and a fertilizer in a small amount about 1/10 to 1/100 that of general practice (clean culture) is supplied to the crop plant when the crop plant starts withering, (5) the operations (3) and (4) are repeated to form a starvation root having strong water absorption power and fertilizer absorption power in the vicinity of ground surface, (6) when a stalk grows about 30 cm length from an apex of a support medium, the stalk is parabolically bent in the direction approximately opposite to the growth direction of the stalk up to now at the top part of the support medium, the stalk is dropped with laying the growth point downward and grown and (7), each branch of calyx is twisted by about 90-120 degrees right and left to slightly damage the surface tissue of the branch.
