However, irrational N application regimes (Liu et al., 2014b; Li et al., 2015) and low plant densities (Liu et al., 2014a) are the key factors limiting the further improvement of crop yield and resource use efficiency in this mulching system. N fertilizer plays a significant role in improving grain yield and WUE (Hernández et al., 2015; Li et al., 2015). Previous research focusing on contrasts in water availability (i.e., rain-fed

“…Compared with CIF, the use of SNWAFI reduced N leaching, leading to greater retention of NO 3 − –N in the upper soil layers while decreasing soil NO 3 –N in the deeper soil layers. Because the irrigation water and N fertilizer are spatially separated in the SNWAFI system, the opportunity for N fertilizer to be dissolved in irrigation water is reduced (Han et al, 2013). Therefore, more N fertilizer will be concentrated in the upper soil layers and available for maize roots, not only reducing N loss but also enhancing N uptake.…”

“…Nitrogen leaching is an important pathway for N loss from agricultural fields, especially in arid and semiarid regions. Nitrogen leaching, due to over‐application of N fertilizer in an attempt to achieve higher crop yields, not only reduces NUE and wastes N fertilizer but also increases the risk of environmental pollution, i.e., drinking water pollution and eutrophication (Han et al, 2013). However, the spatial separation of water and fertilizer can reduce N leaching (Kemper et al, 1975; Xing et al, 2002).…”

“…Computer simulations by Benjamin et al (1997) predicted that less N movement into deeper soil layers would occur if alternate furrow irrigation was managed with N fertilizer placement in the unirrigated furrow. Therefore, to improve furrow irrigation, some researchers have combined spatial separation of water and fertilizer into alternating furrow irrigation (Han et al, 2013; Lehrsch et al, 2001; Skinner et al, 1999; Xing et al, 2002). With SNWAFI, a sidedressing of N fertilizer is applied to an unirrigated furrow on one side of the crop row and irrigation water is applied to the furrow on the other side.…”

The efficient use of water and N represents a primary concern to agricultural production in Northwest China. The objective of this study was to assess the impacts of irrigation and fertilization on water and N use, soil volatilized NH 3 , soil NO 3 leaching, and NO 3 transfer in soil profiles. A 2-yr field experiment was conducted to assess the separation of N fertilizer and water with alternating furrow irrigation (SNWAFI) and conventional irrigation and fertilization (CIF) in a maize (Zea mays L.) production system. The yields with SNWAFI were 10 to 16% greater than with CIF. Compared with CIF, SNWAFI increased water use efficiencies (WUEs) by 13 to 33%, agronomic efficiency of fertilizer N by 36 to 56%, and NO 3 --N in the upper soil layers (0-60 cm) by 30 to 60%. However, SNWAFI reduced NO 3 --N in the deeper soil layers (60-200 cm) by 8 to 44% compared with CIF. The use of SNWAFI also decreased soil NH 3 emission with the combination with lower irrigation (40 mm) and N rate (100 kg N ha -1 ), which indicated that SNWAFI emitted less soil NH 3 than CIF. Therefore, compared with CIF, SNWAFI increased maize yield WUE and N use efficiency, reduced N leaching, and curtailed soil NH 3 loss with appropriate irrigation and N rates. The use of SNWAFI, leading to better spatial management of irrigation water and N application, can provide both agronomic and environmental benefits.

“…Compared to conventional irrigation (CI), PRD decreased plant biomass accumulation by 6.7% Under appropriate fertilization and watered conditions (Li et al, 2010b). Spatially variable water application with PRD causes change of soil moisture within the rhizosphere, influencing N availability and plant N uptake (Han, 2013). Some studies have reported that PRD significantly improved N uptake, with increases of 15 to 100% compared to FPRI, when N application was combined (Zhang et al, 2014;Li et al, 2017).…”

Water stress induces physiological changes in plants, and partial root-zone drying irrigation (PRD) is a water-saving irrigation strategy that can regulate plant physiological responses. This study was to investigate the physiological responses of maize and soybean to PRD and deficit irrigation (DI) under two N-fertilization levels. Plants were grown in a split-root pot culture and were exposed to three irrigation treatments, including full irrigation (FI), DI and PRD, at two fertilization levels (2 and 3 g Pot-1 N). We found that PRD and DI significantly decreased the biomass of two plant species and PRD inhibited less dry mass than DI. Water stress resulted in a higher leaf malondialdehyde content in the leaves of maize and soybean at two fertilization levels, with a smaller increment of PRD than DI. PRD had higher proline content in maize at high N fertilization and in soybean at normal N level than DI. Soluble sugar and protein contents of maize and soybean were higher under PRD than DI at two N levels, except soluble protein content of soybean at normal N level. PRD reduced superoxide dismutase, peroxidase and ascorbate peroxidase (APX) activities of maize and soybean. Moreover, soluble sugar content and APX activity of maize and soybean and proline and protein contents of maize were significantly affected by N treatments. These results indicate that PRD could alleviate the negative effects induced by water stress on maize and soybean through regulation of physiological parameters.
