“…This pattern also reflected on effect of saline irrigations across all the cultivars results in a significant drop at 6.0 EC iw (0.015 g plant -1 ); whereas the P-uptake of cultivars remained statistically at par over four salinity levels. Similar to our findings, some reported that plants under high salinity had the lowest P uptake due to impaired growth in terms of root and shoot dry weights (Brown et al, 2006).…”

Soil salinity remains an obvious abiotic stress that changes the behavior of nutrient accumulation in crop plants. Phosphorus being a key element in determining crop growth and economic yield, its uptake in plant parts varies under saline condition. Hence an experiment was conducted to assess the changing phosphorus content in eight groundnut cultivars,were grown in a field trial having in-built soil salinity developed with 0.5, 2.0, 4.0 and 6.0 dS m -1 of saline irrigations (EC iw ). Root-P was observed to have an increasing trend of accumulation upto 6.0 EC iw while leaf-P increased upto 4.0 EC iw with a concomitant rise in soil P. The cultivars TG 37A and GG 7 accumulated more leaf-P and root-P. However, across the cultivars the P-uptake was reduced when the applied EC iw was 6.0 dS m -1 . Further, these plant-P parameters correlated with the yield and yield attributes of groundnut crop.

“…Uptake of phosphorus was not markedly affected after treatment with NaCl at 0.3 M or below. Similar results were reported for Spartina alterniflora [19] and three soybean cultivars [20]. In the case of phosphorus, its uptake is not significantly affected at NaCl concentration up to 0.3 M but markedly reduced at 0.5 M.…”

“…Wheat (Triticum aestivum) could grow at 0.1 M NaCl and was considered as a moderately salt-tolerant crop [17]. For some halophytes such as Atriplex griffithii and Spartina alterniflora, their growth was stimulated under low salinity stress [18,19]. …”

Abstract. Astragalus adsurgens pall. is a pasture perennial legume widely planted in northern China. A greenhouse experiment was carried out to investigate the effects of salinity on growth, nutrient, organic solute accumulation, pigments and chlorophyll a fluorescence of A. adsurgens seedlings. Seedlings cultured for 20 d under NaCl solutions were harvested and growth, dry matter and ion accumulation were analyzed. The growth parameters except root length were reduced after NaCl treatment. Nitrogen, phosphorus and potassium contents decreased under NaCl salinity stress. Shoot water content decreased with increasing NaCl concentration whereas Na + , Cl -, proline and soluble sugar in shoot increased with increasing NaCl concentration. Moderate salinity (0.3 M NaCl or below) did not inhibit chlorophyll synthesis or photosystem II (PSII) function by inactivation of PSII reaction centers. High salinity (0.5 M NaCl) markedly disturbed chlorophyll synthesis and inhibits PSII activity. A. adsurgens is a salinity-sensitive plant species.

“…Water stress generally favoured increases in nitrogen, K + , Ca 2+ , Mg 2+ , Na + , and Cl -but decreases in phosphorus and iron [147]. Although the many report stated that water stress mostly causes reduction in uptake of nutrients [152], for instance phosphorus, K + , Mg 2+ , Ca 2+ in some crops [153][154][155], Ca 2+ , Fe 3+ , Mg 2+ , nitrogen and phosphorus and potassium in Spartina alterniflora [156]; Fe 3+ , Zn 2+ and Cu 2+ in sweet corn [157]; Fe 3+ , K + and Cu 2+ in Dalbergia sissoo leaves [150], Gerakis et al, (1975) [158] and Kidambi et al, (1990) [159] stated that nutrient elements increased in forage plant species and alfalfa and soinfoin (Onobrychis viciifolia Scop.) respectively.…”
