This study was conducted to investigate effects of cooling methods on the growth and yield of tomato cv. momotaro in the glasshouse for four years from 1996 to 1999. Cooling methods were fan, fan and fogging, fan and shading(temp. control), fan and shading(radiation control), fan and shading (temp. control) with fogging. Fan, Fogging and Shading(temp. control) were operated automatically when air temperature was over 3$0^{circ}C$. Amount of fogging was 500m1/min/100m$^2$and Droplets in a fog were 50 microns or smaller. Shading(radiation control) was operated automatically when solar radiation was over 500W/m$^2$. The growth and yield were the least in fan and shading(temp. control) method due to lack of light Intensity. Fogging method must be reconsidered for expensive equipment and maintenance expenses. As the matter stands, It is suggested to be the most considerable cooling method to increase ventilation rate with fan or use fan and shading(radiation control).
