“…Similar information were published on growth of garlic plants by [20] and [10] who showed that, rice straw mulch produced the highest plant height (70.68 cm), leaves number plant -1 (11.74), fresh leaves weight plant -1 (7.51 g) and dry weight leaves plant -1 (2.91 g). Our results on bulbs yield and its components of garlic were in line with those of [10], [21] and [22] who indicated that, plants of garlic grown under rice straw mulch attained total bulbs yield (5.48 t ha -1 ) which was 31.41% higher than the bare soil (4.17 t ha -1 ).…”

This study was carried out during the winter seasons of 2016 and 2017 at private farm in Beni Suief Governorate, Egypt to investigate the integrative use of potassium levels (24, 48, 72 and 96 kg K2O fed-1) and soil mulching (rice straw and bare soil) on growth and productivity of garlic under three levels of surface irrigation (60, 80 and 100 % of crop evapotranspiration (ETC)). The experimental layout was a spit-spilt plot system based on Randomized Complete Blocks Design. Irrigation levels, potassium rates and mulch types were randomly allocated in the main, sub and sub-sub plots, orderly. The obtained results showed that, the amount of irrigation at 80 and/or 100 % ETC was accompanied increases by plant height, leaves number, leaf area and dry weight plant-1, total bulbs yield, individual bulb weight, cloves weight and number bulb-1 compared to irrigation 60 % ETC. The application of potassium from 24 to 48 and further to 72 and 96 kg K2O fed-1 gave gradual increments in the aforementioned growth and productivity of traits. The rice straw mulch augmented all previous growth, total bulbs yield and its components compared to bare soil. Generally, the 1st order interaction between irrigation percent at 100 and/or 80 % ETC × potassium rate at 96 and/or 72 kg K2O fed-1, irrigation percent at 80 and/or 100 % ETC × rice straw, potassium rate at 96 kg K2O fed-1 × rice straw and the 2nd interaction of irrigation percent at 100 % ETC × potassium rate at 96 kg K2O fed-1 × rice straw mulch had pronounced effects on morphological characters and bulbs yield and its components compared to other combined treatments.

“…For field management, tillage practice, surface mulching, or incorporation with organic (e.g., crop residue, biochar, and compost) or inorganic matter (e.g., plastic film, anthracite coal powder, and gravel) methods are commonly applied for reducing soil evaporation and regulating the salt vertical movement. Meanwhile, subsurface drainage or soil interlayers are reportedly useful in managing groundwater levels and reducing salt accumulation [9][10][11][12]. However, such measures are mainly conducted for soil amendment on primary salinization areas, and rarely on non-saline areas, for preventing or alleviating secondary salinization.…”

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.

“…In our study, the salt distribution might not be affected by only irrigation amount, but also by the mulching. Taia A. Abd El-Mageed [69] conducted a thorough experiment and pointed out that noticeable decrease in salts accumulation in the root zone could be associated with soil mulching application.…”

To investigate better saline water irrigation scheme for tomatoes that scheduling with the compromise among yield (Yt), quality, irrigation water use efficiency (IWUE) and soil salt residual, an experiment with three irrigation quotas and three salinities of irrigation water was conducted under straw mulching in northern China. The irrigation quota levels were 280 mm (W1), 320 mm (W2) and 360 mm (W3), and the salinity levels were 1.0 dS/m (F), 3.0 dS/m (S1) and 5.0 dS/m (S2). Compared to freshwater, saline water irrigations decreased the maximum leaf area index (LAIm) of tomatoes, and the LAIm presented a decline tendency with higher salinity and lower irrigation quota. The best overall quality of tomato was obtained by S2W1, with the comprehensive quality index of 3.61. A higher salinity and lower irrigation quota resulted in a decrease of individual fruit weight and an increase of the blossom-end rot incidence, finally led to a reduction in the tomato Yt and marketable yield (Ym). After one growth season of tomato, the mass fraction of soil salt in plough layer under S2W1 treatment was the highest, and which presented a decline trend with an increasing irrigation quota. Moreover, compared to W1, soil salts had a tendency to move to the deeper soil layer when using W2 and W3 irrigation quota. According to the calculation results of projection pursuit model, S1W3 was the optimal treatment that possessed the best comprehensive benefit (tomato overall quality, Yt, Ym, IWUE and soil salt residual), and was recommended as the saline water irrigation scheme for tomatoes in northern China.
