“…Tissue P and N concentration followed nearly a similar trend for both the uppermost fully expanded leaves and in the whole-plant or whole-plant leaves. The observed decrease (P) or increase (N) in the tissue nutrient concentration under Pi deficiency has also been reported in other studies (Fleisher et al 2012;Singh, Badgujar, Reddy, Fleisher & Timlin 2013). Apparently, due to Pi deficiency the tissue P concentration decreased in greater proportion than the plant biomass leading to markedly increased PUE.…”

Plant mineral nutrients such as phosphorus may exert major control on crop responses to the rising atmospheric carbon dioxide (CO 2) concentrations. To evaluate the growth, nutrient dynamics, and efficiency responses to CO 2 and phosphorus nutrition, soybean (Glycine max (L.) Merr.) was grown in controlled environment growth chambers with sufficient (0.50 mM) and deficient (0.10 and 0.01 mM) phosphate (Pi) supply under ambient and elevated CO 2 (aCO 2 , 400 and eCO 2 , 800 µmol mol −1 , respectively). The CO 2 Â Pi interaction was detected for leaf area, leaf and stem dry weight, and total plant biomass. The severe decrease in plant biomass in Pi-deficient plants (10-76%) was associated with reduced leaf area and photosynthesis (P net). The degree of growth stimulation (0-55% total biomass) by eCO 2 was dependent upon the severity of Pi deficiency and was closely associated with the increased phosphorus utilization efficiency. With the exception of leaf and root biomass, Pi deficiency decreased the biomass partitioning to other plant organs with the maximum decrease observed in seed weight (8-42%) across CO 2 levels. The increased tissue nitrogen (N) concentration in Pi-deficient plants was accredited to the lower biomass and increased nutrient uptake due to the larger root to shoot ratio. The tissue P and N concentration tended to be lower at eCO 2 versus aCO 2 and did not appear to be the main cause of the lack of CO 2 response of growth and P net under severe Pi deficiency. The leaf N/P ratio of >16 was detrimental to soybean growth. The tissue P concentration needed to attain the maximum productivity for biomass and seed yield tended to be higher at eCO 2 versus aCO 2. Therefore, the eCO 2 is likely to increase the leaf critical P concentration for maximum biomass productivity and yield in soybean.

“…Previous studies suggested that Pi deficiency and eCO 2 may also alter the nutrient dynamics and biomass partitioning in the plant organs and affect the assimilation of other nutrients such as nitrogen (Israel et al 1990;Rufty et al 1991;Reddy & Zhao 2005;Fleisher et al 2012;Singh, Badgujar, Reddy, Fleisher & Timlin 2013).…”

“…Tuber yield of all cultivars under low P level was on average 32.4% lower than under high P level, indicating that significant reductions in tuber yield occur when potato plants are grown under P-limiting conditions (Alvarez-Sánchez et al 1999;Dechassa et al 2003;Fleisher et al 2012). In the two P levels, the cultivars Mondial and Agata showed the greatest tuber yield compared with the other cultivars ( Low P High P Low P High P Low P High P Low P High P Low P High P Dry matter partitioning (%) .…”

Phosphorus Uptake, Use Efficiency, and Response of Potato Cultivars to Phosphorus Levels

Utilization of potato (Solanum tuberosum L.) cultivars with greater phosphorus (P) efficiency and response to application of this nutrient is essential to maximize yield, mainly in tropical soils that usually have low P availability. An experiment was conducted under greenhouse conditions in order to evaluate the P uptake rate and the P efficiency for dry matter (DM) production and tuber yield of five potato cultivars (Agata, Asterix, Atlantic, Markies, and Mondial) under low (15 mg dm −3 P) and high (150 mg dm −3 P) P levels. Plants were grown in pots containing 35 dm 3 of a Typic Acrortox soil (31% clay, 4% silt, and 65% sand). Mondial and Agata produced high tuber yield under both P levels due to a high P efficiency. Mondial and Asterix were responsive to P applied regarding the tuber DM production and tuber yield. At high P levels, Asterix, which was inefficient and responsive to P application, had similar tuber yield than Agata, which was P efficient and nonresponsive. Potato cultivars, such as Markies and Atlantic, which were inefficient and responsive to P application regarding shoot or whole plant DM production, might not produce high tuber yield if the DM partitioning to the tubers is low.

“…biochemical model of C 4 photosynthesis (von Caemmerer and Furbank, 1999). Fleisher et al (2012) addressed P deficiency in potato by modifying V cMax (maximum rate of rubisco carboxylation), J (electron transport rate), and TPU (trios-phosphate utilization). Jacob and Lawlor (1992) found less ribulose-1,5-bisphosphate (RuBisCO) in P-deficient maize but did not find decreased activity.…”

The objective of this study was to quantify the response of maize (Zea mays L.) canopy photosynthesis, development and biomass to P under controlled conditions. Maize was grown in Soil‐Plant‐Atmosphere Research (SPAR) chambers in Beltsville, MD, with four levels of P (0 [L], 0.01 [Ml], 0.05 [M2], and 0.2 [H] mmol P L−1) and three levels of N (2, 5, and 12 mmol L−1). Five destructive harvests for biomass were taken. There was no significant N effect, so only the P effects were analyzed, and chambers were pooled over P treatments. Maximum net canopy carbon assimilation in the two lowest P rates was 0.4 g C plant−1 d−1. Carbon assimilation for the M2 rate was half that of the control (1.3 vs. 2.5 g C plant−1 d−1). End of season biomass was decreased relative to the control by 57% in M2 and 79% in L and M1. Leaf appearance rate and area decreased with increasing P deficiency. Differences in tissue P concentrations varied over a narrow range in the P deficiency treatments, suggesting that continued availability of P to maintain growth was important. Decreases in biomass were due to P‐deficiency‐related decreases in leaf growth and photosynthetic rate. Light interception in the low P treatments was near 90%, suggesting that decreases in photosynthesis and leaf growth were due to P effects on metabolic factors rather than reduction in light interception.
