“…This result is in contrast to those obtained by Quanqi et al (2012) and the discrepancy may be explained as follows: irrigation water and rainwater could be collected in the furrow to increase the lower soil layer SWC in the winter wheat growing season, resulting in a higher water penetration ratio in the furrow in the lower soil layer and decreased surface runoff, which led to higher WUE. However, the F planting pattern only retained the lower soil layer SWC at 180 mm of irrigation.…”

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.

“…Crop yield and water use response to irrigation is known to be climate specific; hence the continuous study of the subject by different researchers. Singh et al [1], Al-Jamal et al [2], Imtiyaz et al [3], Camposeo and Robino [4], Mermoud et al [5], Sun et al [6], Nazeer [7], Ayana [8], Quanqi et al [9] are few examples of such studies. According to Kang et al [10], the responses of grain yields and water use efficiency to irrigation varied considerably due to differences in soil water content and irrigation schedule.…”

According to previous reports (Carlowitz and Wolf 1991;Gupta 1994;Zhang et al 2007;Li et al 2008;Quanqi et al 2012), the soil moisture content was higher in furrow planting than in surface planting for the reasons described above. The soil moisture content was higher in the 50 cm pit planting than in the 30 cm pit planting, but this difference was not significant (P > 0.05).…”

This study developed a pit planting technique in which only planting spots were dug to reduce earthwork costs and to enhance tree growth. This technique, in which pits of different depths were dug, was actually applied to a semi-arid experiment site to analyze its effects on soil moisture and tree growth. The soil moisture content in the pit planting 30 cm in depth (30 cm pit planting) and 50 cm in depth (50 cm pit planting) was 6.5 § 0.1% and 6.7 § 0.1%, respectively, which was at least 1.3 times higher (P < 0.01) than that of the control plot (surface planting). The crown growth rate of Populus sibirica trees for 2 years following the planting was 733.5 § 43.3% in the 30 cm pit planting and 889.4 § 58.5% in the 50 cm pit planting which, at their maximum, were 1.7 times higher than in the control plot. The stem diameter growth and the new shoot length were maximally 1.5 times better in the pit planting than in the control plot. The pit planting technique developed will be widely useful to promote the rooting and growth of trees in planting areas with problems of strong winds and dryness.
