| A soil temperature was known as extremely important factor in terms of measuring the values of the growth and yield of vegetable in the greenhouse. A low temperature water irrigation was had much trouble in its growth. This study was performed to analyze the effect of the heating water irrigation on the soil temperature and the growth of a cucumber within a greenhouse environment. Soil temperature was 5-7$^{circ}C$ below to 10cm in depth and 2-3$^{circ}C$ to 20cm when the irrigation water temperature was 13$^{circ}C$ (non-warme water irrigation). Soil temperature was similar to irrigation water temperature at 5cm in depth and was 1.5-2$^{circ}C$ below at 10cm when the irrigation water temperatures were 2$0^{circ}C$, $25^{circ}C$. The early growth rates of heating water irrigation were 109-110% in plant height, 107-108% in leaf number, 103% in node number compared with those of unheated water irrigation for 30 days after planting it. The rates of total yield were 115% in 2$0^{circ}C$ water irrigation plots and 121% in $25^{circ}C$ water irrigation plots while those of unheated water irrigation plots were. |
