“…Overall, it appears that the protein formation in soybean is moderately affected by Mg soil application. In contrast, Vrataric et al (2006) not only reported a significant increase in seed yield upon a single foliar Mg application of 5 % MgSO 4 • 7H 2 O solution during vegetative growth based on 4-year experiment, but also an increase in the protein and oil concentration. A second foliar application after flowering did not further increase the investigated parameters.…”

The significance of magnesium for crop quality

Background The quality of agricultural and horticultural products and its modulation by fertilization has increasingly received attention. However, whereas the importance of magnesium (Mg) as an essential plant nutrient is well established, the impact of Mg nutrition on quality parameters has only been rarely addressed. Scope This review aims at evaluating the available knowledge on the influence of Mg on produce quality. A short discussion on the term quality as used in this review is followed by an overview of the various functions of Mg in plant metabolism in relation to quality aspects. Finally, the available literature on Mg-associated effects on crop quality is critically surveyed. The question whether Mg application beyond yield optimum further improves crop quality is specifically addressed. Conclusion Increasing Mg supply on Mg-deficient sites tends to increase the quality of agricultural crops, particularly when the formation of quality traits is dependent on Mg-driven photosynthesis and assimilate translocation within the plant. In fruits and vegetables, ratios of Mg to other nutrients like Ca and K were shown to be a more reliable indicator of the quality response than the Mg status alone. Moreover, it is concluded that Mg doses beyond those required for maximum yield rarely induce a further improvement of produce quality.

“…Jezek et al (2015) observed an increased leaf Mg content, SPAD index, photosynthetic rate, and accumulation of shoot biomass in corn (Zea mays) subjected to a foliar spray of Mg under controlled conditions. Positive effects on crop yield from spraying foliage with Mg were observed in sugar beet (Beta vulgaris L.) (Barlog & Grzebisz, 2001), soybean (Glycine max) (Vrataric et al, 2006), and fava bean (Vicia faba) (Neuhaus et al, 2014).…”

-The objective of this work was to evaluate the effect of magnesium foliar spray on yield performance of soybean (Glycine max) and corn (Zea mays) cultivated in soil with adequate levels of base saturation and magnesium content in Brazil. The field trials were conducted on a Typic Hapludox cultivated with soybean and corn in the 2013/2014 and 2014/2015 crop seasons, respectively. Treatments consisted of Mg rates (50, 100, 250, 500, 1,000 and 1,500 g ha -1 and a control without Mg) applied during the V4, R1, and R5.1 (soybean) or V4 and R2 (corn) phenological growth stages as magnesium sulfate heptahydrate (MgSO 4 •7H 2 O). The SPAD index, leaf Mg content, grain yield, and 100-grain weight were evaluated. The Mg foliar spray increased the SPAD index in soybean and the leaf Mg content in corn. The Mg rates of 540 and 890 g ha -1 increased in 325 and 737 kg ha -1 the yield performance of soybean and corn, respectively, regardless of the phenological growth stages. The Mg application during the reproductive stages increased in 2% the 100-grain weight for both crops. Foliar spraying of Mg improves the yield performance in soybean and corn crops.

“…Using a bacterial inoculant, Shahid et al (2009) and Afzal et al (2010) obtained an increase in protein content, and Jarecki and Bobrecka-Jamro (2015) an increase in ash content, in soybean seeds. Vratarić et al (2006) reported that foliar fertilization differentiates the chemical composition of soybean seeds, affecting an increase in the contents of protein and fat. Liu et al (2005), using Mo + B applied to soil, achieved an increase in protein content, and after fertilization with Mo, B or Mo + B, a decrease in fat content in soybean seeds.…”

Soybean yields can be considerably improved by inoculation with selected Bradyrhizobium japonicum strains and foliar fertilization. An exact field experiment was carried out in 2012-2014 at the Experimental Station of Cultivar Assessment in Przecław, Poland. The test plant was soybean cv. Aldana. The experimental factors were: bacterial inoculant Nitragina (Bradyrhizobium japonicum); foliar fertilization with Mikrokomplex; combined applications Nitragina + Mikrokomplex and the control treatment. Significant effect of Nitragina on an increase in the number of plants prior to harvest, plant height and the number of pods per plant was indicated. Fertilization with Mikrokomplex caused an increase in the number of pods per plant and thousand seed weight. Nitragina + Mikrokomplex increased the number of plants prior to harvest, plant height, the number of pods per plant and thousand seed weight. Seed yield was significantly higher in all the treatments compared to the control (2.31 t/ha). Higher soil plant analysis development values were found after the application of Nitragina + Mikrokomplex, and in the stage of pod development, also after foliar fertilization with Mikrokomplex. Application of Nitragina and Nitragina + Mikrokomplex resulted in an increase in leaf area index and mean tip angle and total protein in seeds. Fe content in seeds was the lowest in the control (69.2 mg/kg) and significantly higher in the other treatments (Nitragina, Nitragina + Mikrokomplex), and Mg content significantly increased after the application of Mikrokomplex and Nitragina + Mikrokomplex.
