“…In the case of cycle brackish water irrigation, maize irrigated with brackish water at the development stage (i.e., C1) experienced more severe salt stress and suffered a more substantial loss in growth compared to the ones started with brackish water irrigation at the mid-or later stage (i.e., C2 and C3). It is consistent with other cycle irrigation studies (Minhas et al, 2007;Yadav et al, 2007;Singh, 2014;Murad et al, 2018) which state that cycle irrigation with different qualities of water is more beneficial when the better-quality water is applied at early stages because most crops were susceptible to the salinity of irrigation water at the period then switching over to saline irrigation at the later stages when plants are able to tolerate higher salinity level.…”

“…Also, several studies have investigated the effects of saline soil or saline irrigation on maize physiological responses and productivity (Kaddah and Ghowail, 1964; Blanco et al, 2008; Kang et al, 2010; Leogrande et al, 2016; Butcher et al, 2018). Recently, Hassanli and Ebrahimian (2016) reported that cyclic use of saline and non‐saline water increased the water‐use efficiency of drip irrigated maize in a semiarid region, and Murad et al (2018) stated that conjunctive irrigation of saline and freshwater increased maize yield in a saline coastal region of Bangladesh. So far in the coastal areas of eastern China, blending deep‐well water with saline water for agricultural irrigation is a typical practice for extensive coastal farmlands (Yao et al, 2014), and there exists scant information about cycle irrigation with fresh and brackish water.…”

The coastal regions of eastern China have substantial potential for agricultural production. Freshwater scarcity makes the utilization of plentiful brackish water a vital issue in this area. We aim to assess the effects of cycle irrigation with fresh and brackish water on soil salinity and maize (Zea mays L.). A pot experiment was performed with two typical coastal soils (sandy loam and silt loam) and one local maize cultivar. The maize growing season was divided into three phases (development, mid‐, and later stage). Cycle irrigation was conducted using brackish water (5 g NaCl L−1) during one stage and freshwater for the remaining stages. Cycle irrigation using brackish water at the development stage caused both osmotic and ionic stresses on the maize, leading to significantly‐reduced evapotranspiration (ET), increased stem and leaf Na+/K+ ratio, and stunted growth. The decline of kernel number and 100‐grain weight resulted in severe yield loss. Cycle irrigation with brackish water at the mid‐stage induced less adverse effects on crop growth, while the decrease in kernel number remarkably reduced the yield. Cycle irrigation with brackish water at the later stage minimized the impacts of saline irrigation on soil salinity and maize productivity. Nonetheless, salt leaching by off‐season rainfall and low salinity water and soil salt monitoring should be considered before the next season. Compared to sandy loam soil, silt loam displayed higher soil salinization, and lower maize growth and yield. Additional field research is recommended to facilitate the reliable use of coastal soil and water resources. Core Ideas Cycle irrigation with fresh and brackish water in two coastal soils is studied. Cycle irrigation using brackish water is effective when freshwater is scarce. Brackish water is proposed to be used at maize later reproductive stages. Sandy loam soil is preferable for cycle irrigation compare to silt loam soil.

“…These results suggest that as long as the crop can be well established with a starter irrigation and a subsequent irrigation at V8 in maize and crown root initiation in wheat, a yield increase with additional irrigation is unlikely in our study region, except for dry years, as in 2016. In a study conducted near Shatkira, in the southwest of Bangladesh and approximately 250 km from our locations, Murad et al (2018) reported a yield increase of 0.6 Mg ha −1 in 2016 and 0.9 Mg ha −1 in 2017 with the addition of a 3rd irrigation during grain filling of maize. That experiment, which was established on a single-location research station, consisted of plots sown approximately one month earlier than in the current study.…”

Highlights Maize and wheat are proposed for diversification, but irrigation advice is limited. Soil moisture content was above or near drained upper limit for depths below 0.5 m. A significant effect of irrigation on yield was observed for maize only, in one year. One irrigation, in addition to a starter irrigation, generally is sufficient to grow a crop. Low-input maize cultivation is not always profitable and low fertilizer rates increase risk of negative returns.

Potato is one of the sensitive crops to soil moisture stress, which requires a systematic water supply schedule (Ayas, 2013).…”

el-Khaimah, Qalyubiah Governorate. The aim of the current investigation was to study the impact of three planting dates (18-Dec, 7-Jan and 27-Jan), three irrigation levels at 60, 80 and 100% of irrigation water requirements (IR) and their interaction on potato crop productivity. 9 treatments were obtained by combination of different planting dates and irrigation levels.Planting dates were arranged as the main plots, while, irrigation levels were arranged in the sub plots, The obtained results indicated that the highest tuber yield was obtained by the first planting date (18 Dec.) during both studied seasons, While, The highest plant growth parameters and tuber yield per plant were obtained by 100% followed by 80% irrigation level during both seasons. However, the interaction effectindicated that first planting date (18-Dec) combined with 100 % irrigation level gave the highest potato tuber productivity than the other treatments, whereas the interaction of first planting date 18-(Dec) combined with 80% irrigation level gave the best for water use efficiency compared to the other treatments during both tested seasons.
