This study was conducted at Gezira scheme -Sudan during the period from 2009 to 2010 in a heavy clay soil to investigate the effect of management practices on water use efficiency for the different crops irrigated in Gezira scheme. The data was collected from the scheme Administration. The study was organized by using T-Test. Cropwat4 Windows was used to calculate crop water requirements (CWR) and the net irrigation requirements (NIR). The results showed that, Water use efficiency significantly (P ≤ 0.05) affected by the different management practices. Sorghum gave the highest mean value (0.48) of economic water use efficiency as compared to cotton which ranked the least (0.19). Technical water use efficiency for Sorghum and groundnut recorded the highest means values (0.34 and 0.30 kg/m 3 ) while cotton gave the lowest (0.07 kg/m 3 ). Wheat gave the highest mean values (0.87) of Hydraulic water use efficiency as compared to sorghum which ranked the least (0.59). It can be concluded that, proper technical guidelines for irrigation network management, operation and scheduling should be developed and followed.

“…Kang, et al (2002) revealed that, controlled ranges of soil water content during growing seasons can improve the grain yield and water use efficiency. On the other hand Hassanli et al (2009) mentioned that, innovations are needed to increase irrigation water use efficiency and to provide water savings.…”

“…According to [33], evaporation and percolation of irrigation water is reduced while crop development is improved by using drip irrigation system in which water is frequently applied to an area near the roots of plants. As compared to bed-furrow and sprinkler irrigation, water use efficiency and crop production is improved with drip irrigation system [34][35][36][37]. According to [38][39][40], use of drip irrigation system with mulching in recent years has resulted in better application of irrigation water along with fertilizers and pesticides.…”

Traditional irrigation practices, low crop productivity, unlevelled fields, water losses taking place during conveyance and application phases, as well as low irrigation efficiencies are the main problems of the common farmers in Pakistan. These problems are more noticeable in the command area of Lower Chenab Canal (LCC), which is the main portion of the Indus Basin Project in Pakistan. To overcome these problems, different water management technologies such as precision land levelling (PLL), bed planting, drip irrigation systems, and watercourse improvement were introduced to farmers to increase water savings and crop yields in the area of five distributaries-Khurrianwala, Shahkot, Mungi, Khikhi, Killianwala and Dijkot-during the cropping seasons of 2008 to 2015. The use of drip irrigation resulted in savings of water and fertilizer and increased the crop yields by 30-40%. Three watercourses, one on each site of 1200 m in length, were lined, which resulted in improved conveyance efficiency of 15-20%. If wheat, rice and cotton in the command area of LCC are sown on precisely levelled fields and on beds, then about 2768.1 million m 3 and 3699.3 million m 3 of irrigation water can be saved. These results show the potential of water-efficient technologies for saving water as well as increasing crop yields.

Inappropriate irrigation methods lead to loss much water in most upland fields worldwide. Land suitability is one of the good management practices for determining appropriate irrigation methods in upland fields. To determine land suitability, various soil experiments as determination of basic physical soil properties, permeability, saturated hydraulic conductivity and soil moisture characteristics method are important. This study was conducted on soil experiment with the aim to provide a detailed comprehensive understanding of soil capabilities for applying certain irrigation methods in two upland fields, broccoli field (BF) and tomato field (TF), in Mie prefecture of Japan. Soil physical structure properties, water holding capacity, and hydraulic properties were determined using disturb and undisturbed soil samples on laboratory bases. The results obtained showed that TF had deeper effective soil layer of 30 cm, better structure (more porosity, better pores connectivity, and channeling), the water holding capacity of 0.082 mm mm -1 , and higher hydraulic conductivity, compared to BF. It is concluded that TF is suitable for applying shallow surface irrigation method, while the BF have better response on micro-irrigation methods which prevents water pounding in this fields. Application of this approach can improve irrigation practices and efficiency and decreases water loses through accurate irrigation scheduling and application management of irrigation water in upland field agriculture system, especially in dry areas.
