“…Several effective irrigation patterns have been developed, such as limited irrigation, regulation of deficit irrigation, and surge flow irrigation (Fabeiro et al, 2002;Horst et al, 2007;Kang et al, 2000). Deficit irrigation is an optimization strategy that focuses on reducing water use and increasing WUE worldwide (Li et al, 2004;Soundharajan and Sudheer, 2009;Zhou et al, 2007). Evapotranspiration decreases with decrease of irrigation and can significantly contribute to an increase in WUE and grain yield of crops in deficit-irrigation regimes (Jiang et al, 2012;Zhang et al, 1998Zhang et al, , 2008.…”

The world food demand is expected to double by 2050 and the availability and quality of irrigation water is declining because of the needs of the expanding population combined with the effects of climatic change. Therefore, productivity and water‐use efficiency (WUE) are crucial issues in the production of winter wheat (Triticum aestivum L.). The objective of this field study was to compare and evaluate the soil water characteristic, evapotranspiration (ET), yield, and yield components to identify possible ways to improve WUE of winter wheat in the North China Plain. The field experiment in a randomized complete block design with four replicates was conducted during 2008 to 2009 and 2009 to 2010. There were three planting patterns: traditional flat seedbed with uniform row spacing of 25 cm, wide–narrow row spacing of 40‐cm and 20‐cm flat seedbed and furrow‐ridge seedbed; three irrigation treatments: 90, 135, and 180 mm. The results showed that planting pattern and irrigation had significant effect on ET, yield components, grain yield, and WUE (P < 0.05); however, interaction between planting pattern and irrigation only had a significant effect on yield (P < 0.01). Compared with the conventional flat uniform planting pattern, the new treatment of furrow‐ridge seedbed planting pattern increased WUE by 13.7%, increased grain yield by 9.7%, reduced ET by 3.4%, increased soil water content (SWC) by 7.7%, increased soil water storage (SWS) by 6.8%, and increased yield components (grains per spike 15.0%, thousand‐grain weight [TGW] by 3.2%). Irrigation increased upper SWC, SWS, and ET, but decreased WUE. Compared with 90‐mm irrigation treatment, 135‐mm irrigation treatment increased grain yield by 6.4%. The findings suggest that application of the furrow‐ridge seedbed planting pattern combined with 135‐mm irrigation may be an effective strategy to improve winter wheat production in water‐scarce regions.

“…In our previous work, we demonstrated that the seeding-jointing stage was a critical period for amount of population (Zhou et al 2007). RS14 exhibited the highest amount of population and RS49 had the lowest; in effect, the ET of RS14 was significantly higher than those of other treatments (P < 0.05).…”

“…In most years, from October to May, in the winter wheat growing season, rainfall is about 200 mm (20-30% of annual precipitation). The water requirement of winter wheat (~ 400-500 mm) in spring exceeds precipitation; monthly rainfall data shows that water supply from rainfall is inadequate to match crop ontogeny (Zhou et al 2007).…”

The results of two seasons' work on soil water content (SWC), evapotranspiration (ET), total dry matter (TDM), and harvest index (HI) of crops under different row spacing (RS), as well as possible ways to improve water utilization, have been reported. Field experiments were carried out at the Experimental Farm of Shandong Agricultural University (36°09'N, 117°09'E) in 2006-2007 and 2007-2008. Four types of RS were treated under two different water conditions (rainfed and irrigated) and set up in a randomized plot design. RS did not exhibit any obvious effects on SWC during the study period. SWC was enhanced evidently by irrigation, especially in the 10-60 cm soil layer. Irrigation increased the ET of crop. At the seeding-jointing stage, the ET of RS14 was significantly higher than those during other treatments (P < 0.05). Irrigation increased yields, ET, and TDM, while it decreased water use efficiency and HI. There were significantly negative correlations between TDM and RS (P < 0.05). The HI of the rainfed crop was higher than that of the irrigated crop. Results showed that high yields of wheat could be achieved in northern China by reducing RS under uniform planting density conditions.

“…However, the increasing water scarcity and the competition from other sectors have put agricultural water use under great pressure (Yang & Zehnder, 2001;Liu et al, 2007b;Guler, 2010). Irrigation water is becoming an increasingly scarce resource in many areas, as a consequence an appropriate choice of irrigation scheduling is necessary to maximize yield and profit (Zhou et al, 2007(Zhou et al, , 2011. It is known that shoratge of water restricts crop productivity and the purpose of irrigation is to minimise crop water stress and to achieve maximum yield (Ghane et al, 2009;Wang et al, 2009;Ghassemi-Golezani et al, 2015).…”
