of tomato inside the greenhouse is shown in Table 1, and the seasonal
variation of daily ET0 calculated using Eq. (5) is shown in
Fig. 1. The planting dates and the lengths of the two growth seasons
were different (Table 1), correspondingly, the environmental
conditions were different for the two growth seasons. The seasonal
daily averages of Rs, Ta and ET0 were 37, 17 and 56% lower in the
second season than those in the first season; while the daily averages
of RH was 8% higher in the second season than in the first
season
