“…These findings are similar to those reporting that various levels of P applied as a foliar spray caused a reduction in the content of Na + in the shoot of wheat plants (Ghonaim, Mohamed & Omran, 2021). In sandy and calcareous soils, application of P alleviated the stressful effect of moderate and high salinity in wheat plants, while N, P, K + , and Zn 2+ absorption increased (Wagdi et al, 2013).…”

“…Phosphate compounds function inside plants as the "carbon currency" (Ahmed et al, 2018). Additional P application mitigates the reduction of plant growth caused by salinity (Wagdi et al, 2013). Under salt stress conditions, higher P dose caused a reduction in the Na + content in wheat (Wagdi et al, 2013), common bean (Bargaz et al, 2016), and radish (Oliveira et al, 2010).…”

Many agricultural regions in arid and semiarid climate zone need to deal with increased soil salinity. Legumes are classified as salt-sensitive crops. A field experiment was performed to examine the application of phosphorus (P) fertilizer source and rate on growth, chlorophylls and carotenoid content, DNA and RNA content and ion accumulation in common bean (Phaseolus vulgaris L.) cultivated under salinity stress. An experimental design was split-plot with three replicates. The main plots included two P sources, namely single superphosphate (SP) and urea phosphate (UP). The sub-plots covered four P rates, i.e., 0.0, 17.5, 35.0, and 52.5 kg P ha–1. All applied P fertilization rates, in both forms, increased plant height, leaf area, dry weight of shoots and roots per plant, and total dry weight (TDW) in t ha−1. The highest accumulation of N, P, K+, Mg2+, Mn2+, Zn2+, and Cu2+ was determined in the shoot and root of common bean, while 35 kg of P per ha−1 was used compared to the other levels of P fertilizer. The highest P rate (52.5 kg ha−1) resulted in a significant reduction in Na+ in shoot and root of common bean. The response curve of TDW (t ha–1) to different rates of P (kg ha–1) proved that the quadratic model fit better than the linear model for both P sources. Under SP, the expected TDW was 1.675 t ha–1 if P was applied at 51.5 kg ha–1, while under UP, the maximum expected TDW was 1.875 t ha–1 if P was supplied at 42.5 kg ha–1. In conclusion, the 35.0 kg P ha–1 could be considered the best effective P level imposed. The application of P fertilizer as urea phosphate is generally more effective than single superphosphate in enhancing plant growth and alleviating common bean plants against salinity stress.

“…Increasing the P supply reduces the absorption of toxic ions such as Na + that helps plants avoid salinity damage [30]. However, under saline soils, P availability is reduced due to a (a) reduced activity of orthophosphate ions (H 2 PO 4 − and HPO 4 2− ), and the sorption processes; and a (b) lower solubility of Ca-P minerals, which control the concentrations of P in the soil solution [31]. The consumption of P fertilizers has been shown to improve yield and sugar content, as well as stomatal conductance under saline irrigation [32].…”

Soil salinity is a major problem in arid and semi-arid regions, causing land degradation, desertification, and subsequently, food insecurity. Salt-affected soils and phosphorus (P) deficiency are the common problems in the sub-Sahara, including the Southern region of Morocco. Soil salinity limits plant growth by limiting water availability, causing a nutritional imbalance, and imparting osmotic stress in the plants. The objective of this study was to determine the positive effects of P on growth and productivity and understand the major leaf mineral nutrient content of quinoa (Chenopodium quinoa Willd.) cv. “ICBA Q5” irrigated with saline water. A field experiment applying three salinity (Electrical Conductivity, EC) levels of irrigation water (ECw = 5, 12, and 17 dS·m−1) and three P fertilizer rates (0, 60, and 70 kg of P2O5 ha−1) were evaluated in a split-plot design with three replications. The experiment was conducted in Foum El Oued, South of Morocco on sandy loam soil during the period of March–July 2020. The results showed that irrigation with saline water significantly reduced the final dry biomass, seed yield, harvest index, and crop water productivity of quinoa; however, P application under saline conditions minimized the effect of salinity and improved the yield. The application of 60 and 70 kg of P2O5 ha−1 increased (p < 0.05) the seed yield by 29 and 51% at low salinity (5 dS·m−1), by 16 and 2% at medium salinity (12 dS·m−1), and by 13 and 8% at high salinity (17 dS·m−1), respectively. The leaf Na+ and K+ content and Na+/K+ ratio increased with irrigation water salinity. However, the leaf content of Mg, Ca, Zn, and Fe decreased under high salinity. It was also found that increasing P fertilization improved the essential nutrient content and nutrient uptake. Our finding suggests that P application minimizes the adverse effects of high soil salinity and can be adopted as a coping strategy under saline conditions.

“…The adverse effects of salinity on plants grown on P deficient soils and improved wheat growth in moderate and high soil salinity with P are reported. Also, P improved uptake of N, P, K, and Zn in sandy and calcareous soils (WAGDI et al, 2013). The physiology of the wheat plants was stabilized with P application which was due to supporting K transport in the plant (KHAN et al, 2013).…”

Nutrient deficiency is important limiting factor of saline-sodic soils which results in declining crop production in arid climates. The study investigated wheat response to phosphorus and potassium in saline-sodic field of Kohat, Pakistan. The K2O was applied at 0(K0), 75(K1), 150 (K2) kg ha-1 as K2S04 and P2O5 at (0(P0), 60(P1), 120(P2) kg ha-1 as (NH4)2HPO4 in three replications under two-factorial randomized complete block (RCB) design. Both treatments significantly enhanced wheat grain (118%) and dry matter yield (60%) at P2K2 compared to control. The P treatments significantly affected leaf P, Mg, SO4, Ca:P, SO4:P ratios and soil P, Ca:P, Cl:P and SO4:P ratios, while K on leaf K, Na, Ca, SO4concentration, K:Na, K:Ca, SO4:P,Ca:P ratios and soil pH, Na, K, Ca, SO4 concentrations, SAR, Na:K, Ca:K and Na:Ca ratios. Leaf Na was decreased to 85.3 mmol (+) kg-1 at K2 compared to 105.3 mmol (+) kg-1at P2K0. Negative correlation (R2=0.906) of leaf K:Na was found with Leaf Na concentration. Correlation of dry matter was more positive (R2=0.851) with leaf K:Na than grain yield (R2=0.392). It is concluded that K and P addition might be beneficial for improving crop nutrition and wheat yield in saline-sodic soils.
