“…With respect to the interactive effect between inoculating AM, as well as salinity levels and phosphorus application, inoculating AM under any level of salinity with using phosphorus fertilization had no significant effect on Na % in wheat shoots and roots during 1 st and 2 nd stage of planting. Obtained results are in agreement with those obtained by Ali et al, (2000), Akbarimoghaddam et al, (2011), Tahir et al, (2011) Also, Abdel-Fattah and Asrar (2012) Mycorrhizal colonization of a plant with AMF can reverse the effect of salinity on K + and Na + Nutrition. Mycorrhizal colonization can enhance K + absorption under saline conditions Alguacil et al, (2003); Giri et al, (2003) and Zuccarini and Okurowska (2008) while preventing Na + translocation to shoot tissues.…”

There is an inability in facilitating phosphorus under Egyptian soil conditions. For this purpose, a pot experiment was conducted at the experimental farm Faculty of Agric., El-Mansoura Univ. during the winter season of 2008-2009 to investigate the uptake of applied and residual phosphorus by wheat (Triticum aestivum L.) plants as affected by mycorrhizal inoculation under saline condition. Phosphorus was applied at four rates of 0, 50, 75 and 100 Kg/feddan as single super phosphate (15.5%P2O5) under three levels of salinity (1, 6 and 9 dSm-1). Arbuscular mycorrhizal (AM) fungi was used as a mixture including (Glomus mossea, Glomus intraradices and Glomus clarium). The results of this investigation revealed that; with AM inoculation, the mean values of N, P and K% in shoot and roots and Na% in roots were significantly increased. Also, with AM inoculation, the mean value of Na% in shoots decreased. This trend was true during both stages of planting. On contrast, in non-mycorrhizal inoculated plants the illustrated average of N, P and K% in wheat shoot and roots were significantly decreased as the level of salinity increased. On the other hand, the mean values of Na % in wheat shoots and roots were significantly increased due to adding salinity levels over the control during both stage of growth. Concerning the effect of phosphorus application, the average of N, P and K% in wheat shoots and roots were increased significantly over the control. Adding P3 level was superior for increasing aforementioned traits. Addition of P levels, however, had no significant effect on Na% in wheat shoots. This trend was observed during both stages of the experiments. With respect to the interactive effect between adding AM, salinity levels and phosphorus application, it could be realized that adding P3 level with S0 level combined with I1 (AM inoculation) gave the highest value of N, P and K in wheat shoots and roots. However, the mean values of Na % did not significantly affected by treatments of the experiment.

“…In contrast, foliar and soil Si treatments significantly decreased leaf K concentrations compared with the untreated control. In wheat, Tahir et al (2011) found that the addition of Si to irrigated saline water significantly improved K uptake. Kamenidou et al (2008) concluded that there were no differences in the leaf macronutrients (N, P, K, Mg, and Ca), and micronutrients (Al, B, Fe, Na, and Zn) between Si treatments and the control in ornamental sunflower (Helianthus annuus L.).…”

Silicon (Si) plays an important role in plant growth and development, but the uptake, accumulation in tissue, and beneficial effects of Si differ greatly between plant species. Net house experiments were conducted with Cucumis sativus L. 'Shabah F 1 ' in 2013 and repeated in 2014 to determine the effects of Si supplementation on yield, fruit quality, and chemical composition. Diatomite (86-89% SiO 2 ) was applied to cucumber plants three times at two-week intervals after two weeks from transplanting through either foliar spraying (50, 100, 200 mg/l or soil drenching in the root area (500, 1000 and 2000 mg/l). All treatments produced higher early and marketable fruit yield (number and weight) in both years. At all growth stages, application of Si significantly increased fruit firmness, but the effects of Si on total soluble solids varied depending on growth stage and concentration of Si. Significant differences among treatments for ascorbic acid content of cucumber fruits were found in 2013 but not 2014. Tissue analyses showed that Si-treated plants had more Si in the leaves and fruits (% dry wt.), and phosphorus and potassium (% dry wt.) in the leaves compared to untreated controls. We conclude that both foliar sprays and soil drenches of Si have the potential to increase cucumber yield and fruit quality in net house production.

“…Soil salinity generally prevails in arid to semiarid regions around the globe and is among the main causes for reduction of food production. Soil salinity causes physiological drought and ionic toxicity to plants (Acosta-Motos et al 2015) hampering growth and yield of plants (Tahir et al 2011). A number of metabolic and physiological adaptations/mechanisms have been reported in plants to cope with salinity stress (Ashraf et al 2010, Tahir et al 2012.…”

Silicon is known to improve resistance against salinity stress in maize crop. This study was conducted to evaluate the influence of silicon application on growth and salt resistance in maize. Seeds of two maize genotypes (salt-sensitive 'EV 1089' and salt-tolerant 'Syngenta 8441') were grown in pots containing 0 and 2 mM Si with and without 50 mM NaCl. After detailed investigation of ion concentrations in different maize organs, both genotypes were further selected in hydroponic experiment on basis of their contrasting response to salinity stress. In the second experiment, pre-germinated seedlings were transplanted into nutrient solution with 0 and 60 mM NaCl with and without 2 mM Si. Both genotypes differed significantly in their response to salinity. Silicon addition alleviated both osmotic and oxidative stress in maize crop by improving the performance of defensive machinery under salinity stress. Silicon application also improved the water-use efficiency in both tested genotypes under both normal and salinity stress conditions. In conclusion, this study implies that the silicon-treated maize plants had better chance to survive under salinity conditions and their photosynthetic and biochemical apparatus was working far better than that of silicon-non-treated plants.
