However, neither regression line passed through the origin, suggesting a curvilinear relationship at lower evapotranspiration values.
In the semi-arid and arid fringe areas, where evapotranspiration rates are high, salts begin to accumulate on the soil surface over several crop cycles.
It seems that the lower rainfall and higher reference crop evapotranspiration restricted crop water uptake in the early part of 2001.
A reduction in yield may occur when rainfall is insufficient to meet the evapotranspiration demand.
As expected, the longer the maturity of the variety, the higher the total evapotranspiration for the entire season.
The average annual rainfall is 810 mm and potential evapotranspiration 1500 mm.
Phaeozems, by contrast, develop where evapotranspiration exceeds precipitation (showing stress in the middle of the growing season).
This was because they were under the same environmental conditions and so had the same percolation loss and evapotranspiration.
