“…The full plastic film mulch was more conducive in improving soil conditions affecting the yield (Table 4) and especially in reserving water in the profile (Figure 4a) than partial plastic film mulch. This demonstrates that full film mulching enhanced growth conditions by reducing evaporation, increasing infiltration, and accumulating soil thermal energy, and consequently improved grain filling and maturation, as also shown by others [31,32]. Wang et al [28] reported ridge tillage and a full film mulching system in maize cropping efficiently enhanced water retention.…”

Soil hydrothermal condition is one of the most important factors affecting crop growth in arid regions. This study aimed to investigate the effect of mulching and tillage on moisture and temperature variations in soil under drip irrigation in the arid Hetao Irrigation District, northwest China. Four treatments were included: (1) alternating ridges (40 cm wide and 20 cm high) and furrows (40 cm wide) with plots fully mulched with plastic film (RFM); (2) alternating ridges (40 cm wide and 20 cm high) and furrows (40 cm wide) with partial film mulch (only the plant rows mulched) (RPM); (3) flat tillage with plots fully mulched with plastic film (FFM); and (4) flat tillage with partial film mulch (only the plant rows mulched) (FPM). The ridge tillage and plastic film increased soil temperature and significantly conserved soil water, and thus increased the maize yield and water use efficiency (WUE). The RFM treatment had a greater effect than the RPM, FFM, and FPM treatments on the soil moisture and water storage over 0-70 cm in depth during the entire growing period in 2014 and 2015, indicating that full transparent plastic film mulch increased soil water status and promoted deep water percolation, and ridge tillage further enhanced water redistribution to deep soils. Furthermore, RFM proportionally increased soil temperature by 0.36 • C, 1.49 • C, and 1.27 • C above the temperatures under RPM, FPM, and FFM, respectively, in 2014 and by 1.19 • C, 1.62 • C, and 0.35 • C, respectively, in 2015. During the drought year of 2014, tillage influenced temperature more than mulching; however, mulching played a more important role in preserving thermal conditions than tillage during the humid year of 2015. Consequently, RFM increased the maize yield and WUE significantly. We conclude that a combined system of full plastic film mulch and ridge tillage creates beneficial soil hydrothermal conditions under drip irrigation and thus promotes the growth and performance of field crops.

“…Agricultural productivity in semi-arid area is highly dependent on water availability (Li et al, 1999;Ye et al, 2010;Zhao, 1996). The Loess Plateau in northwest of China (Figure 1), covering an areas of 640,000 km 2 or about 6.7% of the total land area of China (Zhang & Liu, 2010), is mainly characterized by a semiarid monsoon climate (also includes a small part of arid and sub-humid areas).…”

“…Low and variable precipitation combined with high evaporation (annual free water evaporation can be three times higher than annual precipitation) often lead to low crop yields on the Loess Plateau (Li et al, 2001;Liu et al, 2009;Wang et al, 2004). Therefore, rainwater harvesting and soil moisture conservation play an important role in agricultural production (Li et al, 1999;Liu et al, 2009;Zhao, 1996).…”

“…Mulches have long been used in agriculture to reduce water loss through evaporation, (Li et al, 1999). The technique has been successfully applied to a number of crops including wheat (Triticum aestivum) (Chakraborty et al, 2008;Li et al, 1999) and maize (Zea mays L.) (Wang et al, 2011a;Zhou et al, 2012).…”

(Wang et al, 2011a;Zhou et al, 2012). Straw is an effective mulch material (Langdale et al, 1992), but the application of straw mulch is restricted on the Loess Plateau because grain yield may be decreased due to lower soil surface temperature (Gao & Zhao, 1995).…”

Mulch and ridge-furrow are effective techniques to improve water harvest, reduce evaporation and increase crop productivity in dry rainfed areas. We collected grain yield data of maize (Zea mays L.) across the precipitation gradient on the Loess Plateau under three treatments: (1) CK, flat plot without mulch; (2) HM, half-mulch flat plot, i.e. alternating mulched row and bare row without ridge-furrow; and (3) DRM, double ridges and the furrow fully mulched with plastic film. Maize grain yields were highest in the DRM treatment and lowest in the CK treatment. Mulch or ridge-furrow with mulch have increased maize grain yield significantly. The highest increase was found in low growing season precipitation regimes. Grain yields of the three treatments trended to converge in high growing season precipitation regimes. Regressions between grain yields and growing season precipitation for the three treatments showed that maize yields increased linearly with precipitation for CK; statistically significant quadratic models were found for HM and DRM treatments. The economic net incomes were calculated based on yields and inputs of capital and labor for the three treatments. Considering both water resource and economic outcome, we recommend that a precipitation range of 196-532 mm is most suitable for mulch and ridge-furrow techniques for maize on the Loess Plateau. Spatially, CK and HM treatment were most suitable for small parts of the southeast part of the plateau and DRM was suitable for most of (87%) the plateau.
