“…Differences in the ability of plants to acquire P exist among different species or varieties within a single species [8][9][10]. Genetic improvement of P efficiency in plants, as achieved through the breeding of P-efficient cultivars, has been utilized to optimize plant production under lower fertilizer use conditions [11][12][13].…”

Grafting provides a way to improve tolerance to low phosphorus (P) stress for plants, and has been extensively applied in commercial cultivars grafted onto appropriate rootstocks. However, little literature is available concerning the scion-mediated effect on P efficiency in grafted plants. In this study, three different Camellia oleifera Abel. scion cultivars (G8, G83-1, and W2) were grafted onto the same rootstock (W2) under controls (0.5 mM) and low-P (0 mM) availability for eight months. The results showed that the scions significantly affected root-to-shoot weight ratios, the root morphology with a diameter larger than 1 mm, P accumulation, and the P utilization efficiency (PUE) of the root. A higher increase in the root-to-shoot weight ratio under the low-P supply was observed in the G83-1/W2 (26.15%) than in the G8/W2 (0%) and the W2/W2 (5.32%). Root PUE of the scion G8, G83-1, and W2 was improved by up to 113.73%, 45.46%, and 20.97% under the low-P supply. Moreover, G8/W2 exhibited higher shoot P accumulation and the highest root PUE under the low-P supply, indicating a high capability to tolerate P deficiency by maximizing the cost-effectiveness of P remobilization to photosynthetic organs. This suggested the vigorous variety of G8 could be a promising scion to improve grafted C. oleifera tolerance to low-P stress. Our results would have important implications for exploration and identification of a superior scion variety to enhance the ability of resistance concerning P deficiency stress in C. oleifera.

“…Therefore, its uptake rates are low. The studies by Nava et al (2017) and Stiles (1994) showed no response to P for apple. Neilsen et al (2008) noted that apple has very low demand for P and that historically studies showed no response to added P. However, they showed increased P uptake and 20% yield increase with P fertigation across several cultivars in their own work.…”

The discovery and development of phosphorus (P) and P fertilizers provide context for current management conventions. Average crop yields were stagnant before the Green Revolution but have steadily increased since. This, along with conventional P management, has resulted in widely depleting soil P levels. Improved technology and management are needed to meet the increasing P demand. Modern hybrids and cultivars have different P demand and uptake patterns that require changes in conventional P fertilizer placement and timing. Phosphorus fertilizer recommendations based on soil analysis remains valid, but evidence suggests a need for recalibrating soil test P (STP) critical levels (the STP concentration at which a response to P fertilizer would not be expected) and P fertilizer rates to accommodate high‐yield scenarios. Considering higher P fertilizer rates as a single solution poses environmental challenges, highlighting the need for improved P use efficiency (PUE). Phosphorus fertilization approaches that have the potential to improve PUE and enable high yields include crop‐specific precision placement of P, informed timing of P fertilizers, and new enhanced efficiency sources of P fertilizer. This paper examines these management approaches from historical, production, and environmental perspectives in modern cropping systems. Core Ideas History of P fertilization illuminates traditional soil P management and needed changes. Recalibration of STP and P fertilizer recommendations are needed to match increasing yield and rates of P uptake. Environmental concerns and diminishing P supply necessitate improvement in P use efficiency. Placement and timing are improved through understanding of variable rooting patterns. Enhanced efficiency P fertilizers can be effective if applied correctly.

“…In Poland, WOJCIK & WOJCIK (2007) applied phosphate and phosphate plus lime to a P deficient 'Jonagold' orchard and reported no increases on fruit yield due to soil P application when the soil pH was adequate. In Brazil, the only paper in the literature reporting the effect of P addition to the soil on apple orchards showed no increases on fruit yield (NAVA et al, 2017).…”

“…In our study, fruit from all treatments, including the control, always had P concentrations above 100mg kg -1 , which is adequate for long-term storage. This high P uptake in the control can possibly be explained by the amount of P released from the organic matter decomposition (NAVA et al, 2017) and by the contribution of mycorrhizae (GASTOL et al, 2016).…”

“…In terms of plant nutrition, fertilization of apple orchards with phosphates has received much less attention than fertilization involving nitrogen (N) and potassium (K). This is mainly because P addition to the soil in established orchards normally has low or no effect on apple yield (NAVA et al, 2017). In addition to a low demand for P, the lack of apple yield response to soil P application is due to the release of reasonable amounts of organic P from the organic matter decomposition, the contribution of arbuscular mycorrhizae fungi, which increase the capacity of roots to take up P, and due to mild winters in subtropical regions, which allows roots to uptake P over the entire year and store it for periods of high demand.…”

Fertilization of apple orchards with phosphorus (P) has received less attention than with nitrogen and potassium. In Brazil, the information about apple response to soil P addition is meager. The objective of this study was to evaluate the long-term effect of annual soil P addition on quality and mineral composition of apple fruits. The experiment started in 2010, in a commercial orchard located in the São Joaquim, Southern of Brazil. The orchard consisted of ´Fuji Suprema’, planted in high-density on a Haplumbrept soil. Treatments consisted of 0, 40, 80, 120 and 160kg ha-1 P2O5 applied annually starting in 2010 broadcast over the soil surface along the tree row. Evaluations were performed from 2012/2013 through 2014/2015 growing seasons. We harvested three samples from each experimental unit. One sample was cold stored in a controlled atmosphere chamber for six months; the others were immediately evaluated for firmness, total soluble solids, titratable acidity (TA), skin color, and the concentrations of N, P, K, Ca and Mg in the fruit flesh. Application of P to the soil affected only flesh firmness at harvest and TA after six months of storage in the 2012/2013 season, as well as firmness after six months of storage in the 2013/2014 season. In the 2014/2015 season, the addition of P reduced fruit color but only at harvest. Addition of P to the soil affected the levels of P in the fruit in the 2012/2013 season, as well as N and the N/Ca ratio of fruit in the 2014/2015 season. Overall, attributes related to fruit quality of cultivar Fuji Suprema were slightly affected by long-term annual addition of P to the soil.
