Water Stress Effect on Yield and Water Use Efficiency of Two Wheat Varieties
Abstract

Wheat is one of the first food crops to be domesticated and is
a basic stable food in Europe, Asia and Africa. Wheat production
is limited by insufficient water especially in the hot dry
environments. In the arid and semi-arid regions, wheat is grown
under irrigation, but its production is threatened by water
shortages caused by pronounced droughts or water
mismanagement. There is therefore need for growing varieties
with improved water use efficiency and good water management
practices to reduce evaporative and other losses. This study
was carried out in Sudan to evaluate the effect of water stress
on yield and water use efficiency of two wheat varieties (Tagana
and Khalifa) under Gezira conditions. The trials was arranged
as a split plot with four replications comprising seven
treatments. Treatments included full irrigation (water applied
every ten days) and other six treatments were imposed by
skipping one irrigation at different crop growth stages. The
highest grain yield of 1400 kg/ha, averaged over wheat varieties,
was obtained by watering every ten days throughout crop
growth. Water use efficiency (WUE) was 87% and 66% for
Tagana and Khalifa, respectively.
