“…Values were comparable with those received 14.4m 3 ha -1 except for 100% of FI. This indicates that incorporation of organic amendments in soil improved soil retention of moisture (Ali et al, 2018). Therefore plants would sustain limited water contents (Hu et al, 2019).…”

Shortage of available water resources has become a critical problem facing vegetable production in Egypt. So, the aim of this study is to decrease the level of irrigation water: 85 and 70% of full irrigation requirements (FI), versus 100% FI in presence of four compost rates (0, 4.8, 9.6 and 14.4 m 3 ha -1 ). Results show that, deficit irrigation levels caused considerable reductions in many growth parameters and the total yield. But we can save 15% of the water used with an average total yield of 39.15 Mgha -1 and a yield shortage of 14.1% in both seasons. This is an acceptable level of decrease in view of the 36.3 Mgha -1 national average according to the 2017 Egypt's Agricultural Statistics. The application of compost at different rates increases the growth, quality and quantity of cauliflower at different water deficiency levels. The highest application rate of compost + 100% of FI recorded the highest values in the characteristics of vegetative growth, total yield and NPK content in curd. The treatment 85% of FI + 14.4 m 3 compost / ha came in the second rank recording significant differences with all other treatments in both seasons. The results also indicate that the water productivity in the case of 85% FI is significantly equal to the water productivity in case of 100% of FI in both seasons. It is; therefore, concluded that compost applications minimized the negative implications of deficient irrigation on cauliflower production.

“…What makes it worse is the uneven seasonal distribution of the scarce precipitation as the rainfall occurs mainly from July to September. This prominent imbalance greatly contributes to the soil water deficit in this region (Wu et al., 2017) and leads to pronounced drought stress and heat stress during the critical growth stage of crops (Ali et al., 2018; Siddique et al., 2012), highly affecting crop productivity in this region. The results indicated that mulching (SM) was an effective way to address this problem, which was realized mainly through the following mechanisms: improving infiltration, reducing the evaporation from soil surface, and increasing soil water retention.…”

“…However, some studies have found that inappropriate mulching amounts and methods can have negative effects (Zhang et al., 2015). The traditional full straw practice often leads to the significant decrease in soil temperature due to low thermal conductivity (Ali et al., 2018; Yan et al., 2018a), and delayed crop emergence, which in turn influence crop growth, and even decrease the yield of wheat ( Triticum aestivum L.) (Yan et al., 2018b), maize ( Zea mays L.) (Linden, Clapp, & Dowdy, 2000; Lu, Li, Sun, & Bu, 2015) and other thermophilic crops due to the shortage of accumulated temperature. Some studies have found that both positive and negative effects existed with the practice.…”

Straw strip mulching affects soil moisture and temperature for potato yield in semiarid regions

Straw mulching is widely used in agriculture to conserve soil water and improve crop productivity. The effects of straw strip mulching and film mulching on dryland soil water storage and temperature, potato (Solanum tuberosum L.) growth and yield, and water use efficiency (WUE) were examined from 2014 to 2015 in the rainfed semi-arid regions of China. Field experiments were conducted with four treatments: (a) alternating strips mulched with maize (Zea mays L.) straw and bare plots with no ridges (SM); (b) alternating large ridges and small furrows with only the ridges mulched with black polyethylene film (PMP); (c) alternating narrows and wide ridges both mulched by black polyethylene film (PMF), and (d) traditional bare land planting without mulching (CK). The results indicated that film mulching had positive effects on soil water storage at the early stage of potato growth, while the SM significantly improved soil water storage at the late growth stage. Soil water storage (0-2-m depth) was 11.3-35.4 mm greater with the SM than that with the other treatments, especially during the tuber bulking in summer drought period. Compared with the CK, the SM significantly decreased soil temperature by 0.8-1.4 • C, and increased potato yield by 10.5-34.2%, WUE by 8.9-29.8%, and commodity rate by 14.7-38.8%. Compared with the PMP and PMF, the SM increased potato yield by 4.6-12.9 and 3.4-9.3%, respectively. This might be contributed to increased soil moisture and lower soil temperature, which promoted potato growth, yield, and commodity rates.Abbreviations: CK, traditional bare land planting without mulching; ET, evapotranspiration; PMF, narrow and wide ridges mulched by black polyethylene film; PMP, large ridges and small furrows only ridges mulched with black polyethylene film; SM, straw strip mulching; SWS, soil water storage; WUE, water use efficiency.

“…Adding crop residue to the soil surface has shown benefits in decreasing soil water evaporation and increasing WUE in semi-arid regions. Ali et al (2018) evaluated different soil management practices and found adding wheat residue at 5 t ha -1 coupled with an irrigation of 350 mm increased soil water availability compared to no residue and increased grain yield by 62% and WUE by 35%. They found that the presence of the wheat residue increased rainfall-use efficiency by 50% because of the reduced soil water evaporation.…”

Water use efficiency (WUE) is defined as the amount of carbon assimilated as biomass or grain produced per unit of water used by the crop. One of the primary questions being asked is how plants will respond to a changing climate with changes in temperature, precipitation, and carbon dioxide (CO 2 ) that affect their WUE At the leaf level, increasing CO 2 increases WUE until the leaf is exposed to temperatures exceeded the optimum for growth (i.e., heat stress) and then WUE begins to decline. Leaves subjected to water deficits (i.e., drought stress) show varying responses in WUE. The response of WUE at the leaf level is directly related to the physiological processes controlling the gradients of CO 2 and H 2 O, e.g., leaf:air vapor pressure deficits, between the leaf and air surrounding the leaf. There a variety of methods available to screen genetic material for enhanced WUE under scenarios of climate change. When we extend from the leaf to the canopy, then the dynamics of crop water use and biomass accumulation have to consider soil water evaporation rate, transpiration from the leaves, and the growth pattern of the crop. Enhancing WUE at the canopy level can be achieved by adopting practices that reduce the soil water evaporation component and divert more water into transpiration which can be through crop residue management, mulching, row spacing, and irrigation. Climate change will affect plant growth, but we have opportunities to enhance WUE through crop selection and cultural practices to offset the impact of a changing climate.
