“…The soil water contents indirectly improve biomass and yield of crops, and increase water DAS -days after sowing; CK -no straw mulching and no nitrogen; N -no straw mulching and 172 kg N/ha; HS + Nhalf straw mulching at a rate of 2500 kg/ha of wheat straw with 172 kg N/ha; FS + N -full straw at a rate of 5000 kg/ha of wheat straw with 172 kg N/ha. Values within a column for the same year followed by different letters are significantly different (P < 0.05) use efficiency (Wang et al 2012, Tao et al 2013. Thereby, sufficient supply of water is beneficial for growth and yield of winter wheat (Zhou et al , 2011a and soil water during the wheat growing season contributed up to 43% in wheat yield (Li and Shu 1991).…”

“…The present study indicated that surface FS + N regime conserves higher soil moisture across the growing season principally during early growth stages compared with CK. The surface application of mulching acts as a physical barrier for reducing evaporation losses, reduces rainfall water runoff and thus increases water storage and slows down air convection on the soil surface (Kang et al 2004, Fan et al 2013. Furthermore, the FS + N regime enhanced soil water storage, so that CK -no straw mulching and no nitrogen; N -no straw mulching and 172 kg N/ha; HS + N -half straw mulching at a rate of 2500 kg/ha of wheat straw with 172 kg N/ha; FS + N -full straw at a rate of 5000 kg/ha of wheat straw with 172 kg N/ha.…”

Field studies using wheat straw mulching effects on soil water storage and maize development were conducted in China. The studies contained four treatments during three years (2014–2016): CK (no straw and no nitrogen); N (no straw mulching with 172 kg N/ha); HS + N (half straw mulching at the rate of 2500 kg/ha with 172 kg N/ha), and FS + N (full straw mulching at the rate of 5000 kg/ha with 172 kg N/ha). The FS + N treatment significantly increased soil water storage in a drought period during crop growth stages and promoted plant growth along with increased evapotranspiration. The FS + N treatment increased the soil water storage (26.5, 19.9 and 11.1 mm), grain yield (28.7, 6.93 and 2.4%), and water use efficiency (26.6, 6.64 and 2.40%) compared to CK, N and HS + N, respectively. In conclusion, compared to N, HS + N or FS + N increased the biomass (11 and 19%) and water use efficiency (4 and 5%), respectively, and are considered beneficial in Guanzhong, China. Mulching levels were superior to N and compensated the wheat nitrogen requirements. Thus, further studies with minimum fertilizer nitrogen for an environmentally friendly and effective approach are recommended in semiarid regions of China.

Intercropping is used to increase grain production in many areas of the world. However, this increasing crop yield costs large amounts of water used by intercropped plants. In addition, intercropping usually requires higher inputs that induce greenhouse gas emissions. Actually, it is unknown whether intercropping can be effective in waterlimited arid areas. Here, we measured crop yield, water consumption, soil respiration, and carbon emissions of wheatmaize intercropping under different tillage and crop residue management options. . Reduced tillage decreased C emission over conventional tillage by 6.7 % for the intercropping, 5.9 % for monoculture maize, and 7.1 % for monoculture wheat. Compared to monoculture maize, wheat-maize intercropping used more water but emitted 3.4 kg C per hectare per millimeter of water used, which was 23 % lower than monoculture maize. Overall, our findings show that maize-wheat intercropping with reduced tillage coupled with stubble mulching can be used to increase grain production while effectively lower carbon emissions in arid areas.

“…A lower water consumption (data not shown) under SS and increased grain yield, indicates improved water use by crops. These results could be attributed to optimized water balance and improved soil physical properties (Fan et al 2012). These results imply that subsoiling can deepen the active soil layer to improve the capacity of soil water harvesting and optimization of water balance in semi-arid environments.…”

“…Nevertheless, some other demonstrated no significant differences between no-till and conventional tillage, or even opposite (Govaerts et al 2009). Some recent reports also addressed faithful question on the potential of no-till in reducing greenhouse gas emissions, increasing C-sequestration (Kirkegaard et al 2014) and improving crop water use efficiency (Fan et al 2012). Straw retention under no-till would be somewhat valid solution to sustain lesser CO 2 emission (Fuentes et al 2011), and in some cases to increase C-sequestration (Alletto et al 2010) and improve soil structure (Zhang et al 2013).…”

In semi-arid areas, increasing CO<sub>2</sub> emissions are threatening agricultural sustainability. It is unclear whether different tillage practices without residue returned could help alleviate these issues while increasing crop productivity. This study aimed to quantify soil respiration under conventional tillage (CT); rotary tillage (RT); subsoiling (SS) and no-till (NT), all without residue returned in the Western Loess Plateau. The results showed that SS and NT significantly decreased soil respiration compared to CT, but the effects of SS was the greatest. As a result, SS decreased carbon emission by 22% in 2014 and 19% in 2015 versus CT. The trends of net ecosystem production under different tillage systems were as follows: CT > RT > NT > SS. No-till increased net ecosystem production by 33% in 2014 and 12% in 2015 relative to CT. The SS treatment increased average grain yield by 27% and 23% over CT and RT, and enhanced water use efficiency by an average of 43%. On average, SS increased carbon emission efficiency by 60% and 43% compared to CT and RT, respectively. Thus, subsoiling management strategy is a promising option for the development of sustainable agriculture in semi-arid areas.
