“…The increased soil evaporation in treatments with SH and a high level of SIR could be explained by (1) the lower IWS treatments that had less salt stress on crop growth and the greater part of the soil water was supplied for transpiration, and the (2) straw incorporation block water upward movement along the soil capillary and limited evaporation from surface soil [22]. Since straw incorporation remarkably increased WUEg and WUEb compared to the non-straw condition, it is possible to improve WUE by modifying the balance between crop transpiration and soil evaporation when soil water dynamics are restricted by the salt effect [38].…”

Secondary salinization induced by brackish water irrigation has forced agricultural development to increasingly rely on soil management. A two-year field experiment was conducted to explore the effects of different straw incorporation rates (SIRs) within 0 to 20 cm topsoil on the soil water–salt balance, maize yield production, and water use efficiency (WUE) under brackish water irrigation in a naturally non-saline area. Air-dried wheat straw was applied at the rates of 0, 4.5, 9.0, 13.5, and 18.0 t ha−1 (R0–R4) and two salinity levels of irrigation water with the salt content of 1.92 dS m−1 (SL) and 3.20 dS m−1 (SH) were applied for simulating the scenarios of secondary salinization. Results demonstrated that straw incorporation markedly increased the soil water content during two growing seasons, and SIR was directly correlated to the deep percolation, but inversely correlated to the soil water depletion, under both the SL and SH condition. Meanwhile, straw incorporation led to the increase in salt content within the straw incorporation zone, but the total mass of salt deposited in the 0–100 cm soil profile was comparatively reduced as SIR increased due to the increased deep percolation for salt leaching, and such relative alleviation was more pronounced under the SH condition. The significantly increased maize yield and its corresponding WUE were obtained in treatments with high SIR levels. Additionally, an exponential function was used to describe the trend of the yield-increasing rate as SIR increased, and the theoretical maximum of grain and biomass yield calculated from the fitting results were 6483 in 17,282 kg ha−1 under SL, and 5440 and 14,501 kg ha−1 under SH, respectively. Results in this study would be helpful in the adoption of straw incorporation and brackish water irrigation in ways that facilitate soil water availability and reduce the risk of soil salinization.

“…The mean annual temperature, sunshine hours and radiation are 12.3˚C, 2938.6 hr and 5592.3 MJ cm -2 , respectively. And the average annual rainfall during the winter wheat growing season from 1996 to 2016 was 125 mm [31]. The average monthly precipitation and temperature from 2013 to 2018 are shown in Fig 1. Weather data were obtained from the Botou Weather Station of China Meteorological Data Service Center, which was about 14 kilometers away from the study site.…”

Insufficient water resources restrict wheat production in the North China Plain, so it is urgent and essential to improve the border irrigation performance and water use efficiency. This study developed a predesigned varied-discharge irrigation scheme in the closed-ended border. Field treatments, including continuous-discharge (CD), increased-discharge (ID) and decreased-discharge (DD) border irrigation tests, were conducted to evaluate the irrigation performance of the proposed varied-discharge scheme. The DD border irrigation treatment had great application efficiency (AE), distribution uniformity (DU) and requirement efficiency (RE), and its comprehensive evaluation indicator (Y) was also significantly higher than other treatments. DD treatment achieved the average AE, DU, RE and Y values of 91.4%, 95.5%, 99.5% and 95.4%, respectively. Furthermore, the hydraulic simulation model WinSRFR was used to optimize the scheme of predesigned varied-discharge border irrigation, and sensitivity analyses of infiltration parameters, roughness coefficient, slope and inflow rate were carried out. The results indicate that the predesigned varied-discharge border irrigation scheme can improve the irrigation performance, and the DD border irrigation scheme has more satisfactory robustness than that of the ID border irrigation scheme.

“…Many researchers have reported that covering the soil with transparent film mulch can improve soil temperatures, compared with not using mulch [26]. As a crop cultivation practice, mulching has been shown to significantly increase the yields of various crops and yield components: strawberry [27]; peach [28]; oilseed rape [23]; maize [29]; spring and autumn potato [30,31]; wheat [32]. Most studies of the mulching film on maize in China used transparent plastic film [33].…”

The experiment was conducted at the experimental field of Sher-e-Bangla Agricultural University during the period from November 2015 to May 2016, Sher-e-Bangla Nagar, Dhaka-1207, to find out the effect of organic mulches on the yield of white maize. This experiment was comprised of two factors. Factor A: Variety (2): V1 = Shuvra; V2 = KS-510 and Factor B: Indigenous mulch materials (5): T1 = Control (without mulch); T2 = Water hyacinth; T3 = Rice straw; T4 = Rice husk; T5 = Ash. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications and the differences between means were separated by both Duncan’s New Multiple Range Test (DMRT) and Least Significant Difference (LSD) test at 5% level of probability. Mulches showed significant effects on most of the parameters. In the case of variety, the highest grain yield (12.963ton per ha) was recorded from V2. Different organic mulch materials showed different values, the highest values were recorded from T3. Due to this (T3) mulch material. The water retentive capacity of the mulched soil was higher at all the stages of plant growth and ranked in the order of rice straw > water hyacinth > rice husk > ash > control. The highest grain yield (17.407ton per ha) was recorded from T3. . In case of interaction all yield attributing characters include grain yield (19.043ton per ha) was recorded from V2T3. So, KS-510 variety and rice straw mulch combinedly had outstanding superiority for morphophysiological and yield attributes in white maize over the other organic mulches.
