“…A number of studies have demonstrated the compensating effect of foliar FA in improving plant growth performance under deficit irrigation conditions . In a pot experiment, the effect of the combined use of two chemicals on yield was superior to the effects of their individual applications . Therefore the combined use of two chemicals could be a practical option for improving corn production under water deficit conditions.…”

In the future, field experiments should be conducted to evaluate economic output in maize production under combinations of FA and SAP in arid and semiarid districts.…”

“…The application of superabsorbent hydrogel to soil promotes irrigation water-use efficiency because of its repeated absorption of soil water and slow release to the crops (Koupai et al, 2008;Liao et al, 2018a), and it reduces crop damage caused by soil water shortage (Khadem et al, 2010;Yang et al, 2014;Cao et al, 2017). Fulvic acid (FA) is a multifunctional growthregulating compound similar to antitranspirants and auxins (Anjum et al, 2011;Zhang et al, 2016;Yang et al, 2017). It has been widely applied to field crops, horticultural plants, and trees in China for over 20 yr (Aggag et al, 2015;Lotfi et al, 2015).…”

“…It has been widely applied to field crops, horticultural plants, and trees in China for over 20 yr (Aggag et al, 2015;Lotfi et al, 2015). Spraying with FA has the potential to reduce water losses by decreasing leaf stomatal transpiration (Li et al, 2005;Calvo et al, 2014), improve plant drought tolerance, and increase crop water-use efficiency (Faralli et al, 2017;Yang et al, 2017). The FA application in wheat increased water uptake by improving root hydraulic conductance and cell membrane permeability (Delfine et al, 2005), and plant adaptability to soil water deficit was enhanced.…”

“…It is currently grown as a dominant crop in central Inner Mongolia in northern China and has a drought index > 3. Precipitation is unpredictable in this region, which receives 250 to 400 mm annual rainfall; approximately 60% of annual precipitation is lost through evaporation, leaving only 25% to 33% for crop growth (Yang et al, 2017). Crop growth thus heavily depends on irrigation from limited water resources.…”

Fulvic acid (FA) and superabsorbent polymer (SAP) are widely applied to improve crop growth and yield under water deficit conditions, but little is known about the changes in crop physiological parameters related to water deficit tolerance when SAP and FA are combined. A pot test with maize (Zea mays L.) plants was conducted to examine the combined effect on photosynthesis, leaf water, proline, and growth under soil water deficit. Maize plants were subjected to two soil moisture conditions at the late crop growth phase: water deficit (WD, 50% field capacity) and well-watered (WW, 80% field capacity). The SAP (4.5 g m-2) was mixed into the soil layer at sowing and the FA solution (2 g L-1) was sprayed twice during water control. The combined application significantly improved maize grain yield under both watering conditions. The net photosynthesis rate, intrinsic quantum yield, fluorescent parameter (Fv/Fm), and chlorophyll content all improved with the combined application under both watering regimes. The compensating effect of combining chemicals on yield and photosynthesis parameters was higher than when applied alone under the two watering conditions. For prolonged and WD conditions, leaf proline and water content were higher under the combined treatment than when used separately. Under the WD conditions treated with FA and SAP, Fv/Fm had positive significant correlations with leaf water content and osmotic potential; leaf proline did not show any correlations with either the osmotic potential or leaf water content. This result demonstrated that SAP and FA could be combined to maintain high leaf proline and improve photosynthesis to mitigate adverse effects of moderate water storage on maize growth.

Organic matter‐derived soil amendments containing humic substances (HS) have a functional role to improve plant growth and soil quality, but their response to water deficit stress is less reported, particularly in vegetable crops. This study assessed the impact of lignite‐derived HS on biota growth and evaluated their potential mitigative effects under water deficit stress in growth chamber and greenhouse environments. Bell pepper (Capsicum annuum L. cv. Revolution) plants were grown in sandy and clay soil previously mixed with lignite‐derived HS and subjected to four irrigation levels (20%, 40%, 60%, and 80%) based on soil water‐holding capacity. Plant growth traits, soil chemical properties, and microbial populations were measured and analyzed. HS increased plant root development and soil bacteria population in moderate and no stress conditions (60%, 80%). Physiologically, HS rapidly decreased leaf stomatal conductance and transpiration after imposing severe or mild stress (20%, 40%). The results indicate that HS transiently ameliorated plants exposed to water stress by reducing moisture loss. In addition, due to their capacity to improve plant root growth, soil nutrient cycling and microbial activity, application of HS might have long‐term benefits in agricultural systems.
