“…The result revealed that, Agronomic Phosphorus Use Efficiency (APUE), Physiology Phosphorus Use Efficiency (PPUE) and Apparent Recovery Phosphorus Use Efficiency (ARPUE) of maize and bread wheat were a highly significantly affected (p˂0.01) by phosphorus doses (Table 3 and 4). Similar results by Irfan et al (2018) and Akhtar et al (2011) in wheat, Saeed et al (2017) in maize and Papadopoulos (1985) in barely who were stated that Phosphorus had significantly affected on agronomic P efficiency (APE), Physiological P efficiency (PPE) and Phosphorus recovery efficiency (PRE). Also, the effect of fertilizer was highly significantly (p˂0.01) on APUE and PPUE in maize and had significantly affected (p˂0.05) on ARPUE in bread wheat.…”

“…The same result to maize and in that time opposite result for bread wheat was found by Saeed et al (2017) who stated while phosphorus doses were in-creasing that means increased agronomic efficiency of maize. Moreover, the opposite result for maize and the same result for wheat that, increased of phosphorus quantity, decreased of Agronomic P efficiency (APE) of the wheat plant depending on the lowest amount of phosphorus (Irfan et al 2018). Furthermore, PPUE in corn at MAP in range 8 -10% also, in wheat at MAP between 13 -42% in addition to at DAP in range 38 -69% were decreased depending on the smallest quantity of phosphorus (30 mg P2O5 kg-1) ( Table 2).…”

Irfan et al (2018) found that when increased phosphorus quantity (0, 30, 60, 120 and 240 mg P2O5 kg-1) so significant (p˂0.05) increased in plant phosphorus uptake and plant dry weight and in same time was Phosphorus fixation in soils is a big problem, for that, it affects negatively on phosphorus use efficiency of the plant. The amount of phosphorus which had fixed depends on orthophosphate ions and some soil properties.…”

“…Being an essential element, P is considered as a major driver for optimum crop productivity on arable land around the globe [2][3][4] . However, suboptimal P availability on arable land forces researchers to determine the mechanisms for improving P acquisition and utilization, and to exploit these responses for the development of P-efficient cultivars 5,6 .…”

This mechanism of P remobilization is responsible for inter-and intra-specific differences in crop plants for P utilization. These traits are heritable and can be exploited to screen plants for high P-efficiency 27 .Rice (Oryza sativa L.) is a major cereal crop known to provide calories to about one third of the population around the globe. According to estimates, global rice harvest removes P from fields of worth around $11 billion each year 28 . Different rice genotypes with higher P-use efficiency can be utilized in rice yield improvement programs. Enhanced internal P-utilization efficiency is required to complement higher P uptake traits for successful breeding of P efficient rice cultivars 29 . Screening of existing germplasm and identification of the responsible P-efficiency mechanism is needed to produce more P-efficient cultivars through conventional as well as molecular breeding ventures. The present study was conducted to identify P-efficient rice cultivars and evaluate the responsible mechanisms for P efficiency in two independent experiments.

Background: Development of an evaluation tool to determine genotypic variation in phosphorus (P) utilization efficiency is essential to ensure crop productivity and farmers' income under low P environments.Aims: This study aimed to develop an evaluation tool to determine genotypic variation in low-P tolerance and P use efficiency under low P environments.Methods: Root response and P efficiency traits in 20 maize genotypes with contrasting root systems were assessed 32 days after transplanting into the semi-hydroponic root phenotyping system under low P (10 µM) or optimal P (200 µM) supply.Results: Compared to optimal P, low P supply increased root-to-shoot biomass ratio by 48.7% (shoot dry weight decreased by 20.0% and root dry weight increased by 20.6%).Low P supply increased total root length by 17.8% but decreased primary root depth, with no significant change in lateral root number across all genotypes. Low P stress enhanced P utilization efficiency. Based on genotypic variation and correlations among the 17 measured plant traits in response to low P stress, nine traits were converted to low-P tolerance coefficients (LPTC), compressed by principal component analysis. The three principal component scores were extracted for hierarchical cluster analysis and classified the 20 genotypes into three groups with different P efficiency, including two P-efficient genotypes and nine P-inefficient genotypes. Conclusions:The study demonstrated genotypic variation in response to low P stress. The P-efficient genotypes with higher LPTC values better adapted to low P environments by adjusting root architecture and re-distributing P and biomass in plant organs. The systematic cluster analysis using selected traits and their LPTC values can be used as an evaluation tool in assessing P efficiency among the genotypes.
