“…Hence, appropriate Mg concentration in leaves is essential to ensure activities of enzymes involved in source-to-sink transport of Mg and sugars, which can be achieved by planting proper species as well as managing Mg fertilizer rates (White and Broadley, 2009). Mg 2+ and closely related sugar production in leaves are of utmost importance for biomass accumulation and grain development (Koch, 1996;Orlovius and McHoul, 2015). Mg 2+ also promotes assimilate partitioning and translocation to source tissues (Cakmak and Kirkby, 2008;Cakmak, 2013).…”

“…We found that sugar concentrations in crops increased when Mg was applied compared to those without Mg application ( Figure 3B). Enhanced sugar accumulation due to Mg fertilization is beneficial for crop production, regardless of plant species (Strebel and Duynisveld, 1989;Marschner, 2012;Orlovius and McHoul, 2015).…”

Magnesium deficiency is a frequently occurring limiting factor for crop production due to low levels of exchangeable Mg (ex-Mg) in acidic soil, which negatively affects sustainability of agriculture development. How Mg fertilization affects crop yield and subsequent physiological outcomes in different crop species, as well as agronomic efficiencies of Mg fertilizers, under varying soil conditions remain particular interesting questions to be addressed. A meta-analysis was performed with 570 paired observations retrieved from 99 field research articles to compare effects of Mg fertilization on crop production and corresponding agronomic efficiencies in different production systems under varying soil conditions. The mean value of yield increase and agronomic efficiency derived from Mg application was 8.5% and 34.4 kg kg -1 respectively, when combining all yield measurements together, regardless of the crop type, soil condition, and other factors. Under severe Mg deficiency (ex-Mg < 60 mg kg -1 ), yield increased up to 9.4%, nearly two folds of yield gain (4.9%) in the soil containing more than 120 mg kg -1 ex-Mg. The effects of Mg fertilization on yield was 11.3% when soil pH was lower than 6.5. The agronomic efficiency of Mg fertilizers was negatively correlated with application levels of Mg, with 38.3 kg kg -1 at lower MgO levels (0-50 kg ha -1 ) and 32.6 kg kg -1 at higher MgO levels (50-100 kg ha -1 ). Clear interactions existed between soil ex-Mg, pH, and types and amount of Mg fertilizers in terms of crop yield increase. With Mg supplementation, Mg accumulation in the leaf tissues increased by 34.3% on average; and concentrations of sugar in edible organs were 5.5% higher compared to non-Mg supplemented treatments. Our analysis corroborated that Mg fertilization enhances crop performance by improving yield or resulting in favorable physiological outcomes, providing great potentials for integrated Mg management for higher crop yield and quality.

“…Moreover, after optimum level of Mg (13 kg ha -1 ) tuber yield reduced by 3.83 kg for additional use of one kg Mg ha -1 . Orlovius and McHoul, (2015) studied the impacts of magnesium fertilizers at rate of 60 kg Mg ha -1 (25 kg Mg fed -1 ) on yield, quality and leaf concentrations of magnesium in potatoes and sugar beet. They found that there were clear increases in leaf Mg concentration and yield resulting from application of Mg fertilizers.…”

Calcium (Ca) and magnesium (Mg) are of the secondary nutrients that required by plants for healthy growth. So, two field experiments were conducted at Kafr Bosat Village, Talkha District, Dakahlia Governorate, Egypt (Latitude 30° 43 ' 22.01" N, Longitude 30° 16' 44.50" E) during the winter growing seasons of 2014/2015 and 2015/2016 to investigate the effect of foliar Ca and Mg application and their interactions on the growth, yield, quality, nutrient concentration and uptake of potato crop (Solanum tuberosum, L. -c.v. salany) that grown in clay loam soil. The experiment was designed as a spilt plot design with three replicates; the main plots were assigned for three levels of foliar application of Mg; Mg 0, Mg 1 and Mg 2 (control, 0.2 and 0.4 % Mg as magnesium sulfate), and the sub plots were devoted to three levels of foliar Ca; Ca 0, Ca 1 and Ca 2 (control, 0.6 and 0.8 % Ca as calcium nitrate). Results showed the importance of Ca and Mg supplies, where they illustrated that foliar application of Ca and Mg levels significantly increased plant growth parameters at 90 days as plant fresh weight, leaf area and chlorophyll a, b and total concentrations; tubers yield and its quality as % of dry matter, starch and protein contents, and uptake of N, P, K, Ca and Mg (kg fed -1 ) in shoots and tubers at harvest. Plant tuber yield and average tuber weight increased with increasing foliar application of Ca, whereas number of tubers plant -1 was decreased. Also, results at 90 days, demonstrated that foliar application of Ca and Mg levels significantly increased N, Ca and Mg concentrations in leaves, but K concentration was decreased. At harvest, tubers content of N, P, K, Ca and Mg increased significantly with foliar application of Ca up to Ca 2 (0.8 % Ca) and spraying with Mg up to level Mg 1 (0.2 % Mg). Interaction between foliar application of Ca and Mg levels had a significant effects on plant growth parameters, tubers yield and its quality and nutrients uptake in dry shoots and tubers yield. The highest values of tubers yield (17.251 ton fed -1 ), dry matter % of tuber (24.78 %), starch % (18.24 %) and contents of N, P, K, Ca and Mg in shoots and tubers were recorded by the interaction of Ca 2 ×Mg 1 . It could be concluded that foliar applications of Ca and Mg at 0.8 % Ca as calcium nitrate and 0.2 % Mg as magnesium sulphate were more important to improve plants growth and increase tubers yield and their quality under this conditions.

“…Cakmak and Yazici explained that an adequate supply of Mg is essential for plant uptake of Mg and is important for different physiological processes of the plant. Furthermore, the application of Mg fertilizer in higher solubility forms significantly increased the Mg concentrations and yields of potato and sugar . In our research, we found that the maize under the WM3 treatment accumulated a greater amount of Mg than that for maize under the WM0 treatment.…”

BACKGROUND Magnesium (Mg) has important effects on maize growth, and the application of Mg fertilizer with straw return inevitably has an impact on Mg absorption in maize. RESULTS A two‐year field trial was conducted to investigate the effects of Mg fertilizers with straw return on Mg accumulations, partitioning and remobilization in maize (Zea mays L.) in northeast China. The treatments included: (i) JM3 (straw + Mg fertilizer), (ii) JM0 (straw + no Mg fertilizer), (iii) WM3 (no straw + Mg fertilizer), and (iv) WM0 (no Mg fertilizer + no straw). The results showed that the highest Mg accumulation stage in maize was prominent between the tasseling stage (VT) and blister stage (R2), and JM3 treatment accumulated 13.3% and 26.6% more Mg on average than those of the WM3 and WM0, respectively. Magnesium remobilization in distinct organs was highest in JM3 and there were significant differences between treatments. The total contribution to the grain for the JM3 treatment was higher by 6.0% and 17.9% on average than those for the WM3 and WM0, respectively. The grain yield of JM3 treatment was 0.5% and 5.3% higher than that of WM3 and WM0, respectively. CONCLUSION Generally, these outcomes indicated that there was an interaction between Mg fertilizer and maize straw. The application of Mg fertilizer significantly promoted the accumulation, distribution to the maize organs, and the remobilization of Mg. The combination of straw return and Mg application further increased the accumulation of Mg in the grain. And all these lead to an increase in yield. © 2020 Society of Chemical Industry
