Improving Growth and Nutrient Content of Maize and Cotton Plants through Magnesium Nitrate Foliar Fertilization

Influence of Magnesium in Combination with Organics on the Yield and Uptake of Nutrients by Cotton (Gossypium hirsutum L.) Crop in Typic ustropept

“…It was determined that applying Mg via roots causes rivalry for K absorption from the soil, but applying Mg via foliar provides no competition for Mg uptake of K due to the absence of Mg as a competitor at the root side and lower Mg concentration in root tissues. Similar findings were provided by Mobarak et al, [4] Potassium suppresses Mg absorption through non-specific Mg transporters on root cell membranes, resulting in large reductions in Mg concentrations in plants reported by Senbayram et al, [20].…”

“…Cotton is often cultivated on heavy clay soils with a high pH (>7.0), where Mg uptake is restricted due to increased calcium buildup and their antagonistic interaction effect (Fageria, 2001). Foliar feeding is an efficient approach to raise Mg content in different regions of the plant and boost yield when compared to soil application of Mg nutrients, and comparable results have been found in cotton by Mobarak et al, [4] and Singh, Rathore, and Gumber [5].…”

“…Poor soil conditions such as soil compaction, drainage impedance and surface waterlogging, surface capping and other factors restricting root development and Mg uptake will result in symptoms of Mg deficiency rather than an absolute shortage in soil In clay loam soil, the most effective application of Mg fertilizer increased Mg content in cotton (Gossypium barbadense var. Giza 75) leaves (0.67-0.82 percent), stems (0.18 0.31 percent), and roots (0.39 0.52 percent) [4]. Delfani et al, [25] found that foliar application of Mg Nano particles enhanced Mg absorption in stems and leaves of black-eyed pea (Vigna unguiculata) when compared to normal Mg salt, suggesting that Mg nanoparticles are more available and mobile.…”

Economics and Nutrient Uptake by Blackgram as Influenced by Secondary Nutrients and Zinc Nutrition

“…Higher calcium concentration inhibits the uptake of magnesium due to decrease in the permeability of cells (Fageria, 2001) owing to this the uptake of magnesium in the calcium foliar spray decreased despite of higher dry matter accumulation. The positive results of magnesium foliar application on uptake of magnesium and zinc was reported by Rady and Osman (2010), Mobarak et al, (2013) and Howladar et al, (2014).…”
