Performance of Counter-Poise ‘Shadouf’ in Zalengi Area, West Darfur State, Sudan*

Abstract

This study was carried out to determine the performance of the
counter-poise ‘Shadouf’, which is widely used along Wadi Azum in
Zalengi area, West Darfur State, Sudan, to irrigate small holdings. The
study included data collection on ‘Shadouf’, crop water requirements and
soil characteristics; namely, mechanical analysis and hydraulic
conductivity. The results showed that the ‘Shadouf’ has an average
discharge rate of 1.34 ℓ/s, enough to irrigate an area of 0.22 feddan (1 fed.
= 0.42 ha) during winter or 0.18 feddan during summer when the device is
operated for six hours per week.
