dc.description.abstract | In this study the energy balance approach is applied to
determine the evapotranspiration rates over a crop of sunflower
of the giant variety. Three series of measurements were taken
when the crop was 1 meter high, 1! meters high and 3 meters high.
The technique used is that of the Bowen ratio method which consisted
of hourly values of dry bulb temperature, wet bulb temperature
and wind speed at two levels above the crop from 8 a.m. to 5 p.m.
local time. Furthermore flux measurements were made and these
consisted of net radiation and soil heat flux. The instruments
were mounted on an aluminium mast which permitted the alteration
of the positions of the·instruments with plant growth. | en |
