The purpose of this study was to provide basic data used in greenhouse design, and for this purpose, the crop loads of tomato and paprika which have high crop load among crops cultivated in greenhouse were measured. The maximum differences in lowest and mean temperatures between cultivation year and normal years for winter season were -5.6 and $-4.9^{\circ}C$, respectively and those for summer season were 3.0 and $1.5^{\circ}C$, respectively. The calibration of push & pull gauge indicated approximate 0.99 of coefficient of determination, representing very high association. The planting densities of paprika and tomato were 3.43, 3.56 and $2.13plants{\cdot}m^{-2}$, respectively. The yields were 4.1, 4.3 and $16.2kg{\cdot}plant^{-1}$, corresponding to 14.1, 15.2 and $34.5kg{\cdot}m^{-2}$ of yield per unit area. The maximum loads were 1.3, 1.5 and $3.3kg{\cdot}plant^{-1}$, respectively. When the paprika were hanged on cross beam, the total crop load applied to it was estimated to be $15.3{\sim}15.9kg{\cdot}m^{-2}$, and when the weights of gutters supporting the cultivation beds, the total weights were $26.0{\sim}26.9kg{\cdot}m^{-2}$.

This study was conducted to provide basic data needed to calculate the crop loads for the greenhouse design. Four countries' crop loads for greenhouse structures were compared and the crop loads were measured directly and analyzed for various greenhouse crops, including tomato, strawberry, cucumber, and eggplant. According to the analysis results of four country's standards for the design crop loads, it was judged that the new design crop loads suit for greenhouse crops in our country should be suggested because our standards just used the design crop loads of other countries. The maximum crop loads per plant of tomato, cucumber, eggplant, and strawberry were 3.9, 0.75, 1.9 and $2.1kgf{\cdot}plant^{-1}$, respectively. The crop load per unit area of tomato was $8.5kgf{\cdot}m^{-2}$, which was much greater than the cucumber and eggplant's crop load of 2.1 and $2.4kgf{\cdot}m^{-2}$ respectively. The crop loads of tomato and cucumber, suggested by the greenhouse structure design standard of Korea, is $15kgf{\cdot}m^{-2}$, which is far greater than the values suggested by this research. It was judged that this was because our standard just used the Dutch standard, our crop load standard should be reviewed considering this difference. The crop load of strawberry, including the growing bed, was $21.0kgf{\cdot}m^{-2}$, which was much greater than the crop load in the Dutch standard.
