“…On the other hand, with RDI, the high coefficient of variation led to a decrease in the level of statistical significance, with similar results shown by Erdem et al (2005). The lack of statistical significant differences between IRs for some parameters may be consequence of their high values of CV, which might be reduced using larger plots as stated by McCann et al (2007). Some researchers have stated that IWUE is not affected by IR, such as Erdem et al (2005)..…”

Water is an essential resource for food production, as agriculture consumes close to 70% of the 15 total freshwater, and its shortage is becoming critical in arid and semiarid areas of the world. 16 Therefore, it is important to use water more efficiently. The objectives of this project are to 17 determine the productive response and the irrigation water use efficiency of seedless watermelon to 18 three irrigation management strategies over two growing seasons. This was done by applying 100, 19 75 and 50% of the irrigation water requirements (IWR) the first year, in the second year added six 20 additional treatments, of which three treatments were regulated deficit irrigation with 75% IWR 21 during the vegetative growth, fruit development and fruit ripening stages, and the other three 22 treatments were with 50% IWR during the same stages. The exposure of watermelon plants to 23 severe deficit irrigation resulted in a reduction in dry biomass, total and marketable yield, average 24 fruit weight, fruit number and harvest index, and without improvement of marketable fruit quality. 25 The fruit ripening was the less sensitive stage to water deficits. Relative water content and cell 26 membrane stability index decreased as the water deficit increased. Irrigation water use efficiency 27 decreased to a lesser extend during the fruit ripening stage than when water restriction were 28 applied during different growth stages. If water is readily available, irrigating with 100% of water 29 requirements is recommended, but in the case of water scarcity, applying water shortage during fruit ripening stage would be advisable.

“…Laboratory testing and field trials more often investigate how plastic mulch may increase crop yield rather than how it may conserve irrigation water (Ricotta and Masiunas 1991, Easson and Fearnehough 2000, Xie et al 2005. Some studies have considered how the use of plastic mulch may conserve soil moisture; however, these studies most often involve the use of drip irrigation (Tiwari et al 2003, Amayreh and Al-Abed 2005, McCann et al 2007), instead of surface flood irrigation techniques most often applied in developing countries.…”

Plastic mulch is commonly used with micro-irrigation in developed countries; however, Chinese farmers use plastic mulch on a vast scale independent of micro-irrigation. For the past three decades, China's land area in plastic mulch has exceeded the world's total land area in micro-irrigation. We report results from the water-scarce region of Minqin County, where 87% of Chinese farmers interviewed responded that they use plastic mulch to conserve water and 53% to increase yields. Survey results indicated the desire to conserve water through the use of plastic mulch to be statistically equivalent to the desire to increase yields. Responses to interviews and surveys indicate that farmers perceive water savings of 24-26% when plastic mulch is used. Interview and survey responses suggest farming families are shifting to purchasing wheat from outside the region; a potential import of ''virtual water'' into this water-scarce region.

“…Cucurbit demand for water is relatively high compared to many other annual cereal and vegetable crops. Cucurbits irrigated with DI and SDI are generally irrigated for long durations at each irrigation event and frequently, particularly in the tropics and sub-tropics (McCann et al, 2007). Such crops tend to develop sustained wetting fronts especially in fine textured soils (Thabet and Zayani, 2008), which predisposes the rhizosphere to a gradual lack of oxygen (hypoxia), leading to a deficit of oxygen in the root zone (anoxia).…”

Lack of oxygen due to sustained wetting fronts associated with drip and subsurface drip irrigated crops in heavy clay soil can negatively impacts on yield, fruit quality and water use efficiency of cucurbit crops. This study evaluated the effects of aerated irrigation water (oxygation) with subsurface drip irrigation, employing an in-line air injector (Mazzei venturi to introduce 12% air by volume of water) on fruit yield, quality and water use efficiency of watermelon (Citrullus vulgaris) and pumpkin (Cucurbita maxima) in a heavy clay soil. The fruit yield with oxygation increased from 14.5 t ha -1 to 24.6 t ha -1 , and 26.3 t ha -1 to 28.9 t ha -1 , for watermelon and pumpkin, respectively. The total soluble solids (TSS) increased by 19% with oxygation (13.2 vs. 11.1%), and internal fruit crack decreased for watermelon, whereas in pumpkin fruit dry matter increased by 4% (40 vs. 38.4%) and TSS by 7% (13.7 vs. 12.8%). Season long water use efficiency was greater with oxygation compared to the control in both crops. The higher yield with oxygation was associated with a more rapid canopy cover, more leaf chlorophyll, and an increase in leaf photosynthetic rate, and leaf transpiration and an increase in fruit number and size. The results suggested that oxygation can ameliorate temporal hypoxia-associated with drip irrigated cucurbit crops in heavy clay soil and also offer yield and fruit quality benefits.
