“…The ratio of soil water consumption to crop evapotranspiration (Δ SW / ET a ) during the growing season for FI was 0.23 whereas that for DI was only 0.10. DI reduction of soil evaporation has been also demonstrated elsewhere (Lamm et al, ; Reyes‐Cabrera et al, ; Shock, Pereira, & Eldredge, ) to be distinctly different at different growth stages. In addition, the non‐beneficial water loss by soil evaporation under FI may result in salt accumulation in the root zone, which could be a contributing factor affecting crop yields.…”

“…As shallow groundwater can contribute to crop water requirement, less irrigation water is needed by irrigation (Liu et al, ; Reyes‐Cabrera et al, ). The soil water distribution during this period is quite distinct between FI and DI.…”

“…Deep drainage can be greatly reduced in DI compared with FI. Thus, applications of DI help stop groundwater level rising in shallow groundwater areas, which reduces the risk of secondary salinization (Kang et al, ; Reyes‐Cabrera et al, ). On a large scale, a change of irrigation practice can lead to a change of water balance of the entire irrigation region.…”

Shallow groundwater plays a key role in agro‐hydrological processes of arid areas. Groundwater often supplies a necessary part of the water requirement of crops and surrounding native vegetation, such as groundwater‐dependent ecosystems. However, the impact of water‐saving irrigation on cropland water balance, such as the contribution of shallow groundwater to field evapotranspiration, requires further investigation. Increased understanding of quantitative evaluation of field‐scale water productivity under different irrigation methods aids policy and decision‐making. In this study, high‐resolution water table depth and soil water content in field maize were monitored under conditions of flood irrigation (FI) and drip irrigation (DI), respectively. Groundwater evapotranspiration (ETg) was estimated by the combination of the water table fluctuation method and an empirical groundwater–soil–atmosphere continuum model. The results indicate that daily ETg at different growth stages varies under the two irrigation methods. Between two consecutive irrigation events of the FI site, daily ETg rate increases from zero to greater than that of the DI site. Maize under DI steadily consumes more groundwater than FI, accounting for 16.4% and 14.5% of ETa, respectively. Overall, FI recharges groundwater, whereas DI extracts water from shallow groundwater. The yield under DI increases compared with that under FI, with less ETa (526 mm) compared with FI (578 mm), and irrigation water productivity improves from 3.51 kg m−3 (FI) to 4.58 kg m−3 (DI) through reducing deep drainage and soil evaporation by DI. These results highlight the critical role of irrigation method and groundwater on crop water consumption and productivity. This study provides important information to aid the development of agricultural irrigation schemes in arid areas with shallow groundwater.

“…Application of drip irrigation may lead to up to 70 % higher profitability of potato production in comparison to seepage irrigation (Matovic et al, 2016). Reyes-Cabrera et al (2016) says that drip irrigation uses 48 % to 88 % less water compared to seepage irrigation, with the same yield levels of most potato varieties. Some varieties, however, show yield drops after drip irrigation application in comparison to seepage.…”

A small-plot field experiment started in 2016 studied effect of drip irrigation on potato tuber yield and starch levels in the tubers. Two potato varieties with different vegetation periods (Monika, Jolana) were exposed to four drip irrigation intensity levels. They were non-irrigated controls and irrigated tubers with 60 %, 65 % and 70 % usable soil water capacity levels. The other studied parameter was represented by the effect of nitrogen fertilisation with the nitrogen nutrient added to the irrigation water (fertigation) in the course of the vegetation period in contrast to one-off application of the whole nitrogen dose before the potato planting. All irrigated variants in comparison to the non-irrigated controls showed 30 -60 % yield increase. The effect of fertigation on yields was statistically insignificant. Starch levels in the tubers were mostly affected by the variety. The irrigated variants in comparison to the non-irrigated controls showed higher starch levels in the harvested tubers but the differences were statistically insignificant.

“…It reduces soil evaporation and weed population, increases plant transpiration, and when well-managed, excessive water drainage is unlikely to occur, thus allowing nutrients to be retained in the root zone for prolonged periods. Moreover, drip offers an opportunity to inject soluble fertilizers combined with irrigation, a process known as fertigation (Cabrera et al, 2016).…”
