Abstract:
This study was conducted to outline the different operation conditions and aspects
related to the irrigation practices and irrigation management in Eljuomoeia scheme
during seasons (2008-2009), (2009-2010).A questionnaire model was designed,
hundred farmers samples randomly were selected. The collected data was analyzed
using statistical package for social sciences (SPSS).The questionnaire revealed the
irrigation problems which can be summarized in the following: Irrigation water
shortage during a part of a season, low water level while necessitates using the
small lift pumps ,increasing in total cost percentage for irrigation during the season
ranges between (71.8% - 91.1%), lack of a clear contract to organized the relation
between the farmer and the scheme body. Determination the overall efficiency was
carried out by estimation. Pumping efficiency, conveyance, distribution and
application efficiency. Computer programme (Crop.Wat) was use to calculate crop
water requirements for Tomato, Okra and Abu sabein to determine the peak water
requirement during the season. This was compared to the net water supply of the
scheme. The study showed that irrigation efficiency are Pumping efficiency
76.5%,conveyance 79.6%,water distribution 73.88% and water application
efficiency 57.14% to give an overall poor irrigation efficiency25.6%.In addition to
that there is water irrigation deficit that extends for six months. Maximum
irrigation water deficit reaches (50%-53%) during October and November. On the
other hand there is surplus irrigation water capacity at the beginning of the season
(150%-264%). The study recommendations can be summarized as: The out of
service pump should be put to service to compensate for the shortage of water at
the season peak, the intensification of cropping pattern during the surplus period
programmes for canals and water control structures can be made under direct
technical supervision
