“…This meant a reduction of about 182% compared to the Control, and about 55% regarding the combined application of Zn and urea. Wang et al (2015) also found significant decreases in phytate:Zn ratios with soil applications of Zn. Supposing the intake of 100 g bread made with these whole grains treated with Foliar or Soil + Foliar treatments may provided about 4 to 4.8 mg Zn, about one third of the Zn RDI for humans, and about 2.7 times more than the same intake of non-biofortified wheat.…”

The combined application of nitrogen (N) and zinc (Zn) appears to be a promising agronomic strategy for the biofortification with Zn. To evaluate such efficiency, a field experiment was conducted in south-eastern Portugal under Zn-deficient soil. Four advanced breeding lines and two commercial varieties of bread wheat (Triticum aestivum L.) were fertilized with five treatments: i) control, ii) two foliar Zn applications, iii) one foliar Zn+N application, iv) soil and two foliar Zn applications, and v) soil and one foliar Zn+N application. Grain Zn content varied greatly across treatments and INIAV-1 and the commercial varieties were the most interesting cultivars in all the treatments. Grain Zn concentrations higher than the target level of 38 mg Zn kg -1 were obtained only when two foliar Zn applications were applied, alone or in combination with soil Zn applications, and grain Zn bioavailability also was more adequate (phytate:Zn ratios similar to 15). Soil Zn application resulted in grain yield increases between 7-10%, which virtually offset the extra application cost. The combined soil and two foliar treatment could be a good option for biofortifying bread wheat under Zn-deficient soils.

“…Agronomic Zn biofortification has been shown to be effective in increasing Zn in common dietary foodstuff Ghasemi et al 2013;Wang et al 2015;Gomez-Coronado et al 2016). Cereals, being consumed in large amounts, could constitute a major source of Zn in the diet, estimated by Terrés et al (2001) in about 25%.…”

“…However, residual effects are likely to provide benefits for several years for both wheat and other crops (NFDC 1998;Singh and Shivay 2013;Manzeke et al 2014;Wang et al 2015b). Third, foliar Zn applications could make up a larger proportion of future Zn fertiliser-use, especially if it is applied in conjunction with pesticide sprays to minimise additional costs of application (Wang et al 2015a;Ram et al 2016). Fourth, if other hostile soil factors, such as B deficiency or salinity/sodicity, are addressed through soil management practices to improve yields, then greater returns per unit input of Zn are possible (NFDC 1998).…”

“…3-11:1;NFDC 1998). In addition to yield increases in the year of Zn fertiliser application, there may be beneficial residual effects of Zn fertilisers for subsequent crops for three or more years (NFDC 1998;Singh and Shivay 2013;Manzeke et al 2014;Wang et al 2015a). However, despite these potential financial returns, Zn fertilisers remain little utilised in Pakistan and elsewhere, for several reasons.…”

Background Sprouting is known to improve cereal and pulse nutritional properties. However, several outbreaks of illness have been reported after raw sprout consumption. This research aimed to improve wheat sprout hygienic properties through the use of zinc diacetate. Sprouting conditions (sprouting temperature, soaking time and zinc diacetate solution concentration) were optimized to decrease total plate count, coliforms, and molds and yeasts using a factorial design approach and a desirability function. Results Based on the responses, the effects of variables were calculated and the interactions between them were determined. Optimal conditions were defined as follows: sprouting temperature 18 °C, soaking time 0.66 h and zinc diacetate concentration 400 mg L−1. These conditions led to the elimination of coliforms and a decrease in total flora count by 2 log. Interestingly, zinc sprouting increased the zinc content of sprouts and improved their nutritional properties. Conclusion Results showed that the use of zinc solution is a useful tool to improve sprout hygienic and nutritional properties. © 2019 Society of Chemical Industry
