“…However, phosphorus uptake by plants, in the form of phosphate ions, depends on soil physicochemical parameters ( Pereira et al., 2020 ), the application method and its frequency ( Rady et al., 2018 ; Chtouki et al., 2022 ), the root exudation and architecture ( Khourchi et al., 2022a ), and the rhizosphere microbial activity ( Wahid et al., 2020 ). In this regard, different studies have proven the effectiveness of phosphate solubilizing bacteria (PSB) in improving crop yield due to improved P levels in the soil ( Khourchi et al., 2022b ).…”

Salt stress impacts phosphorus (P) bioavailability, mobility, and its uptake by plants. Since P is involved in many key processes in plants, salinity and P deficiency could significantly cause serious damage to photosynthesis, the most essential physiological process for the growth and development of all green plants. Different approaches have been proposed and adopted to minimize the harmful effects of their combined effect. Optimising phosphorus nutrition seems to bring positive results to improve photosynthetic efficiency and nutrient uptake. The present work posed the question if soluble fertilizers allow wheat plants to counter the adverse effect of salt stress. A pot experiment was performed using a Moroccan cultivar of durum wheat: Karim. This study focused on different growth and physiological responses of wheat plants grown under the combined effect of salinity and P-availability. Two Orthophosphates (Ortho-A & Ortho-B) and one polyphosphate (Poly-B) were applied at different P levels (0, 30 and 45 ppm). Plant growth was analysed on some physiological parameters (stomatal conductance (SC), chlorophyll content index (CCI), chlorophyll a fluorescence, shoot and root biomass, and mineral uptake). Fertilized wheat plants showed a significant increase in photosynthetic performance and nutrient uptake. Compared to salt-stressed and unfertilized plants (C+), CCI increased by 93%, 81% and 71% at 30 ppm of P in plants fertilized by Poly-B, Ortho-B and Ortho-A, respectively. The highest significant SC was obtained at 45 ppm using Ortho-B fertilizer with an increase of 232% followed by 217% and 157% for both Poly-B and Ortho-A, respectively. The Photosynthetic performance index (PItot) was also increased by 128.5%, 90.2% and 38.8% for Ortho-B, Ortho-A and Poly B, respectively. In addition, Poly-B showed a significant enhancement in roots and shoots biomass (49.4% and 156.8%, respectively) compared to C+. Fertilized and salt-stressed plants absorbed more phosphorus. The P content significantly increased mainly at 45 ppm of P. Positive correlations were found between phosphorus uptake, biomass, and photosynthetic yield. The increased photochemical activity could be due to a significant enhancement in light energy absorbed by the enhanced Chl antenna. The positive effect of adequate P fertilization under salt stress was therefore evident in durum wheat plants.

“…The CND, CLREF, and CLRND methods had negative values for the net increase in production (Table 6), reflecting the inability to identify true cases of nutritional deficiency for B. Teixeira et al (2002) found Net d(Y) ranging from 20 to 70 t ha -1 in banana due to the correct diagnoses provided by CLREF for N and K. Silva et al (2020) evaluated the quality of the nutritional diagnosis of P by the CND method in sugarcane and reported negative values for Net d(Y). Morais et al (2019) verified that the CND method was the most suitable when compared with the CLCAL method to diagnose P in eucalyptus seedlings cultivated under a controlled environment using the Dickson quality index as a yield criterion to calculate Net d(Y).…”

“…Studies on the efficiency of nutritional diagnosis methods in soybean have only been indirectly conducted by comparing diagnoses produced by different methods (Urano et al, 2007;Kurihara et al, 2013) and without evaluating plant response to the nutritional assessment prognosis. Some authors have evaluated the performance of nutritional diagnosis for most crops based on plant response to correct the nutritional status (Beverly and Hallmark, 1992;Beverly, 1993;Morais et al, 2019;Silva et al, 2020).…”

The efficiency of the boron (B) nutritional status in soybean (Glycine max (L.) Merr.) was evaluated by degree of agreement (DA) indicators using different diagnostic methods and by prescient diagnostic analysis (PDA). The objective of this study was to evaluate the efficiency of two interpretation methods of B nutritional status in soybean, that is, compositional nutrient diagnosis (CND) and critical level (CL). An experimental trial was conducted using a randomized block design with five replicates, which evaluated foliar B application rates of 0, 300, 600, 1200, and 1800 g ha -1 . Another study consisted of monitoring 140 commercial farms. We sampled leaves to determine nutrient contents and estimate yield in both studies. All samples were diagnosed by CND and CL methods. A reference value in the literature was obtained by the reduced normal distribution and CL methods by field calibration in the experimental trial. All the methods showed a high DA between diagnoses; the efficiency ratio and accuracy for true deficiency were both low, except for the CL method by field calibration, which exhibited an increase in positive net yield. The DA was ineffective to validate the efficiency of nutritional diagnoses; methods with a higher DA showed negative values for the net increase in production (-46 to -53 kg ha -1 ). The CL method by field calibration showed greater efficiency in assessing the nutritional status of B in foliar fertilized soybean because the net increase in production was 197 kg ha -1 .

“…Consequently, the increased levels of toxic ions such as sodium and chlorine (Na + and Cl − ) negatively impact plant growth and yield by limiting water uptake and causing ion toxicity, which can lead to nutrient imbalances 6 . This has a significant effect on the root’s capacity to absorb water and results in stomatal closure altering CO 2 assimilation 7 and therefore photosynthesis efficiency 8 . Later, an imbalance of the photochemical phase takes place in chloroplasts, causing a series of secondary stresses including oxidative stress 9 , 10 where the continued exposure results in plant death 11 .…”

“…However, salt-stressed plants showed positive results after the optimisation of P nutrition in salt-affected soil 31 – 33 , 38 , 40 , 41 . Additionally, it is important to state that phosphorus absorption by plants differs depending on the physicochemical parameters of the soil 8 , the exudation and architecture of roots 42 , the method and frequency of P fertilizer application 43 , 44 , and the microbial rhizospheric activity 45 , 46 . In this regard, Kohler et al 47 found that the salt tolerance of lettuce plants was enhanced by Pseudomonas mendocina resulting in a decrease of catalase activity with an enhancement in the dry weight of leaves and proline concentration.…”

By 2050, the predicted global population is set to reach 9.6 billion highlighting the urgent need to increase crop productivity to meet the growing demand for food. This is becoming increasingly challenging when soils are saline and/or deficient in phosphorus (P). The synergic effect of P deficiency and salinity causes a series of secondary stresses including oxidative stress. Reactive Oxygen Species (ROS) production and oxidative damage in plants caused either by P limitation or by salt stress may restrict the overall plant performances leading to a decline in crop yield. However, the P application in adequate forms and doses could positively impact the growth of plants and enhances their tolerance to salinity. In our investigation, we evaluated the effect of different P fertilizers forms (Ortho-A, Ortho-B and Poly-B) and increasing P rates (0, 30 and 45 ppm) on the plant's antioxidant system and P uptake of durum wheat (Karim cultivar) grown under salinity (EC = 3.003 dS/m). Our results demonstrated that salinity caused a series of variations in the antioxidant capacity of wheat plants, at both, enzymatic and non-enzymatic levels. Remarkably, a strong correlation was observed between P uptake, biomass, various antioxidant system parameters and P rates and sources. Soluble P fertilizers considerably enhanced the total plant performances under salt stress compared with control plants grown under salinity and P deficiency (C+). Indeed, salt-stressed and fertilized plants exhibited a robust antioxidant system revealed by the increase in enzymatic activities of Catalase (CAT) and Ascorbate peroxidase (APX) and a significant accumulation of Proline, total polyphenols content (TPC) and soluble sugars (SS) as well as increased biomass, Chlorophyll content (CCI), leaf protein content and P uptake compared to unfertilized plants. Compared to OrthoP fertilizers at 45 ppm P, Poly-B fertilizer showed significant positive responses at 30 ppm P where the increase reached + 18.2% in protein content, + 156.8% in shoot biomass, + 93% in CCI, + 84% in shoot P content, + 51% in CAT activity, + 79% in APX activity, + 93% in TPC and + 40% in SS compared to C+. This implies that PolyP fertilizers might be an alternative for the suitable management of phosphorus fertilization under salinity.
