“…Thus, several water-saving methods have been developed (Belder et al, 2004;Bouman et al, 2006), surrounded by deficit irrigation and may possibly to improve agricultural water use. Our results are in agreement withthose of Rao and Bhardwaj (1981);Zhang et al (2001); Nasseri and fallahi, (2007) and Qiu et al, (2008). They observed under deficit irrigation and on applying irrigation at critical growth stages WUE increased.…”

Total Dray Matter (TDM), Photosynthetically Active Radiation Intercepted (PARabs), Water Consumption (WC), Water use-(WUE), Radiation use efficiency (RUE) and the relationship between Radiation Interception and Water Consumption for Durum Wheat were investigate under different irrigation amount (D 1 = 100 % ETc; D 2 = 70 % ETc; D 3 = 40 % ETc and D 4 = pluvial) and during three growing seasons (2005-2006, 2006-2007 and 2007-2008). Results showed that, the cumulative PAR abs decreased with deficit irrigation. In fact, D 1 treatment recorded the highest cumulative PAR abs and the lowest marked underD 4 treatment. Similarly, TDM and RUE were decreased with deficit irrigation. The highest RUE observed under the D 1 (from 1.32 to 1.43 g MJ -1 ) and the lowest under D 4 (from 1.17 to 1.29 g MJ -1 ). However WUE increased with deficit irrigation. The highest WUE were obtained under the D 4 (from 3 to 4 kg m -3 ) and the lowest were observed under D 1 (from 2.8 to 3.1 kg m -3 ). Significant linear relationship was found between cumulative PAR abs and cumulative water consumption with a high correlation coefficient (R 2 ) only under the two treatments D 1 and D 2 .

“…Therefore, soil moisture in the root zone of RF was relatively higher than that of F and MD during the whole season. Crop water consumption has a positive relationship with growth indicators [38]. There was a decrease for RF and an increase for F and MD in soil moisture after cotton harvesting, which was attributed to greater water consumption in RF because of its greater RLD and aboveground growth indicators ( Figure 4 and Table 2).…”

Flat (F), mini-ditch (MD), and ridge-furrow (RF) are three conventional cotton planting patterns that are usually adopted around the world, yet soil and crop responses to these three patterns are poorly studied, as is their suitability for increasing yield for coastal areas in Eastern China. The effects of three planting methods on water and salt dynamics as well as on growth and lint yield of cotton (Gossypium hirsutum L.) were investigated in a saline field in Bohai Rim, China, to select the best planting pattern for cultivating coastal saline fields of Eastern China. Soil moisture in the root zone with RF was 11.9% and 12.1% higher than with F and MD, whereas the electrical conductivity of a saturated soil extract (EC e ) in the root zone with RF was 18.0% and 13.8% lower than with MD and F, respectively, during the growth period, which indicated that RF could efficiently collect rainfall and leach salt in the root zone. After drip irrigation, the infiltration and salt-leaching depth with RF were both deeper than that with F and MD. The stand establishment of MD was the highest (80.3%) due to the greenhouse effect from film mulching, and was 12.8% and 4.6% higher than that with F and RF, respectively. Growth indicators and lint yield demonstrated that RF was superior to F and MD because of the higher soil moisture and lower EC e . The lint yield was significantly higher in RF, suggesting that RF can be an optimal planting pattern for agricultural reclamation in similar saline-alkaline areas around the world.

“…When water supplies were withheld, increasing values of HI resulted in better WUE. However Zhang et al (2008) investigated the correlation between water supplies and HI in winter wheat; they found a reduction in HI parallel to an increase in the water supplies. The present results indicated that, in the case of wheat varieties, changes in HI and WUE paralleled each other, so that HI declined to varying extents in response to water withholding, except for the most droughttolerant varieties.…”

Water use of winter cereals under well-watered and drought-stressed conditions

et al. 2013

A reduction in the water available to plants will lend increasing importance to the dynamics of water uptake and to the water use efficiency (WUE) of cereals. The effect of drought on the water use efficiency of winter cereals was investigated in a greenhouse experiment in the Centre for Agricultural Research. The effect of water deficiency on the water use properties was studied by measuring changes in the grain weight, thousandkernel weight and aboveground biomass. The water use efficiency of wheat varieties generally ranged from 1.5-2.3 kg/m 3 and 1.06-2.0 kg/m 3 in the case of optimum and limited water supplies, respectively, while these figures were 1.4 kg/m 3 and 0.8 kg/m 3 for winter barley and 0.8 kg/m 3 and 0.5 kg/m 3 for winter oat. Investigation on the relationship between harvest index (HI) and WUE was found that the harvest index is only one indicator of drought tolerance; but the stability of HI under non-optimum environmental conditions also needs to be determined.
