Estimation of long-term reference evapotranspiration using limited weather data in sugar beet plantation area from Middle Anatolian, Turkey
Abstract
The
Konya basin, Middle Anatolian region, is one of the most important agricultural
area in Turkey. The region is in a semi-arid area with average annual rainfall
ranging from 280 to 500 mm. Sugar beet is the vital commercial crop in this
area that is the largest producer of Turkey. Water requirement of the sugar
beet and evapotranspiration is very high during the growing season in the
basin. The Food and Agricultural Organization of United Nations Penman-Monteith
(FAO56-PM) equation requires accurate weather data like air temperature,
relative humidity, solar radiation and wind speed. Unfortunately, not all these
input data are possible to reach easily. Therefore, FAO56 suggested another
equation that is Hargreaves – Samani (HS) equation when sufficient weather data
are not available to estimate FAO56-PM. This study estimates ETo using by HS
equation. For this purpose, daily maximum and minimum temperature data
collected along the period 1986-2015 from sugar beet plantation area located in
Konya basin. Finally, this study estimates long-term reference
evapotranspiration to give the idea of water loss in a semi-arid area.
