To investigate the effect of early-morning heating periods on growth and yield of cucumber and heating load in a greenhouse cultivation, three additional heating periods (0, 1 and 2 hours) were compared to rise temperature from $12^{circ}C;to;16^{circ}C$ in the early-morning. Leaf temperature just before opening the thermal screen was $3.3^{circ}C;and;4.1^{circ}C$ higher in the 1 and 2 hour heating compared to that in the control (0 hour heating), respectively. Photosynthetic rate, conductance to $H_2O$ and transpiration rate of cucumber leaves were the highest in the 2 hour heating, and the lowest in the control. However. the difference between the 1 hour and 2 hour heating was not significant. Inorganic element content in cucumber leaves was not significant among the treatments of duration. Initial growth after planting of cucumber was greater in the 1 and 2 hour heating than that in the control. Yield increased by $11%;and;15%$ in the 1 hour and 2 hour heating compared to that in the control. respectively. Fuel consumption for heating increased by $12%;and;22%$ in the 1 hour and 2 hour heating compared to that in the control, respectively. Considering in the yield and fuel consumption for heating. 1 or 2 hours of early morning heating could be effective in temperature management for cucumber in a greenhouse cultivation.
