“…Moreover, these genotypes could be utilized in wheat breeding programs to improve P use efficiency. Similar results for the significant differences among wheat genotypes in APUE at different P levels have been reported other researchers in the past (Ozturk et al, 2005;Yaseen and Malhi, 2009;Bilal et al, 2018;Deng et al, 2018;Meier et al, 2021).…”

Increasing wheat production has become an urgent requirement to cope with rapid population growth and abrupt climate change. The management of phosphorus (P) and nitrogen (N) is one of the most important factors for sustaining and increasing wheat production, particularly in semiarid environments. This 2-year field study, which aimed to investigate the effect of P levels (0, 35, and 70 kg P2O5 ha−1) and N forms (urea, ammonium sulfate, and ammonium nitrate) on the yield attributes of three diverse high-yielding commercial wheat cultivars (‘Shandawel-1’, ‘Sids-14’, and ‘Sakha-95’), was carried out at Om-Elzain Village, Zagazig, Egypt. The results indicated that increasing P levels was accompanied by a substantial increase in all evaluated traits, except spike length, and that high P level (70 kg P2O5 ha−1) was superior. Considerable genetic variation was detected among the evaluated cultivars for all studied traits. Cultivar ‘Sakha-95’, followed by ‘Sids-14’, presented the most vigorous growth and enhancements in most yield components, grain yield, and biological yield. Furthermore, ‘Sakha-95’ recorded the highest agronomic P use efficiency, followed by cultivar ‘Sids-14’. N forms did not significantly affect all of the tested traits except plant height, spike number m−2, and 1000-grain weight, during both seasons. Ammonium-containing fertilizer (ammonium sulfate and ammonium nitrate) resulted in the highest values for these traits when compared with urea. Accordingly, ‘Sakha-95’ and ‘Sids-14’ are recommended for commercial use under high P levels. N forms had a marginally substantial effect on grain yield and its attributes.

“…It is well documented that the individual or the combined effects of drought and P deficiency affect photosynthetic activity, nutrient uptake, and plant growth and yield 35 , 42 , 44 , 45 . The previous studies dealing with the interaction between water and P were mainly focused on the effect of P rate applied or P concentration in the soil solution on crop growth and development 20 , 34 , 46 . To the best of our knowledge, this is the first study that investigated the interactive effects between P fertilizer form (with a focus on Ortho-P and Poly-P) and soil water content on chickpea photosynthetic activity, plant growth, water and nutrient uptake, and their use efficiency.…”

“…P use efficiency is mainly dependent on P mobility and availability in the soil 16 , 17 . The capacity of plants to take up P is strongly related to many soil characteristics and parameters as well as to the fertilizer properties such as pH, fertilizer form and solubility and its interaction with the soil moisture and compounds 18 – 20 . For example, the application of orthophosphate (Ortho-P) fertilizers under high alkaline soil conditions resulted in high interaction between P ions and other bivalent cations, which can lead to the formation of some insoluble P forms, and consequently reduce P uptake and recovery by plants 21 .…”

Water shortage and soil nutrient depletion are considered the main factors limiting crops productivity in the Mediterranean region characterized by longer and frequent drought episodes. In this study, we investigated the interactive effects of P fertilizer form and soil moisture conditions on chickpea photosynthetic activity, water and nutrient uptake, and their consequent effects on biomass accumulation and nutrient use efficiency. Two P fertilizer formulas based on orthophosphates (Ortho-P) and polyphosphates (Poly-P) were evaluated under three irrigation regimes (I1: 75% of field capacity, I2: 50% FC and I3: 25% FC), simulating three probable scenarios of soil water content in the Mediterranean climate (adequate water supply, medium, and severe drought stress), and compared to an unfertilized treatment. The experiment was conducted in a spilt-plot design under a drip fertigation system. The results showed significant changes in chickpea phenotypic and physiological traits in response to different P and water supply regimes. Compared with the unfertilized treatment, the stomata density and conductance, chlorophyll content, photosynthesis efficiency, biomass accumulation, and plant nutrient uptake were significantly improved under P drip fertigation. The obtained results suggested that the P fertilizer form and irrigation regime providing chickpea plants with enough P and water, at the early growth stage, increased the stomatal density and conductance, which significantly improved the photosynthetic performance index (PIABS) and P use efficiency (PUE), and consequently biomass accumulation and nutrient uptake. The significant correlations established between leaf stomatal density, PIABS, and PUE supported the above hypothesis. We concluded that the Poly-P fertilizers applied in well-watered conditions (I1) performed the best in terms of chickpea growth improvement, nutrient uptake and use efficiency. However, their effectiveness was greatly reduced under water stress conditions, unlike the Ortho-P form which kept stable positive effects on the studied parameters.

“…Recently, Refs. [25,26] identified an interactive role between phosphorus use efficiency (PUE) and WUE in winter and spring wheat genotypes, opening up the possibility of selecting P-efficient wheat genotypes that will also exhibit efficient water use, constituting a new approach to overcome water deficit stress and promote food security under future climate change scenarios.…”

The relationship between phosphorus (P) availability and water restriction was explored in this study, focusing on its impact on phosphorus use efficiency (PUE) and water use efficiency (WUE) in various bromegrass (Bromus spp.) genotypes. Under controlled conditions, five bromegrass genotypes, as well as one ryegrass (Lolium perenne) cultivar, were compared by subjecting them to two P levels and two watering regimes. It was determined that combining water and phosphorus limitations led to reduced plant productivity. Initially, the ryegrass outperformed the bromegrass, but this result declined over time, while bromegrass exhibited consistent stability. Notably, under P and water stress, enhanced root development was observed in bromegrass compared to that in ryegrass. Distinct patterns of PUE and WUE allowed for the categorization of bromegrass genotypes into three groups. Genotype 3457 emerged as the most efficient, scoring 20 out of 24, while Pro 94-49 A achieved a score of only 10 out of 24. This study suggests that the drought resilience of bromegrass may be linked to increased root growth during the early vegetative stages, which potentially facilitates improved P acquisition. However, further validation through long-term field experiments is needed. The insights from this study are potentially valuable for use in shaping plant breeding programs by revealing the plant adaptation mechanisms for both P and water absorption.
