“…The most commonly used form of Zn in both granular and foliar fertilisers is ZnSO 4 .7H 2 O. Other forms of Zn including Zn-bonded amino acids may be more effective at increasing grain Zn concentrations (Ghasemi et al 2013), however insufficient studies were identified to include alternatives to ZnSO 4 in this review. The effect of Zn fertiliser was quantified as concentration of Zn in the grain at harvest as a percent of control and the median effect was used across studies by taking study site, crop type, cultivar, application method (soil or foliar) and application rate (kg Zn ha −1 ) as factors.…”

Background In this review, we examine the potential of Zn-enriched fertilisers to alleviate human dietary Zn deficiency. The focus is on ten African countries where dietary Zn supply is low and where fertiliser subsidies are routinely deployed on cereal crops. Scope Dietary Zn supply and deficiency prevalence were quantified from food supply and composition data. Typical effects of soil (granular) and foliar Zn applications on Zn concentrations in maize (Zea mays L.), rice (Oryza sativa L.) and wheat (Triticum aestivum L.) grains were based on a systematic literature review. Reductions in disease burdens attributable to Zn deficiency and cost-effectiveness were estimated using a disability-adjusted life years (DALYs) approach. Conclusions Baseline Zn supply in 2009 ranged from 7.1 (Zambia) to 11.9 (Mali) mg capita −1 day −1

“…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%.…”

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.

“…The foliar application of fertilizers is an effective agronomical practice in crop production, with a substantial influence on both yield and particularly grain quality (Ghasemi et al 2013). In this study, there was investigated the effects of foliar spray fertilizers with free amino acids (Aton AZ) on photosynthetic parameters and growth of barley plants, which were exposed to UV-B radiation and drought stress.…”

The impact of foliar spray fertilizers (Aton Az) on the resistance of spring barley (Hordeum vulgare L.) against to individual and combined UV-B radiation and drought effects were investigated. Barley seeds were sown in pots prepared with neutral pH peat substrate. When the 2 nd true leaf unfolded, i.e. 7 days after germination, the first spray with microelement and free amino acid fertilizers was carried out; two days after this application, the different irradiation (1 and 3 kJm -2 d -1 ) UV-B doses and drought effects were started. Exposure lasted for 6 days. The main characteristics of all investigated indicators were assessed at the end of exposure. The largest positive effects of fertilizers on the photosynthetic rate and water use efficiency of barley were found solely under the impact of drought. Foliar spray fertilizers decreased oxidative stress injury in the leaves by decreasing the malondialdehyde content under solely effects of drought and UV-B radiation, while under the combined effect of the mentioned stress factors, the changes were statistically insignificant. A stronger positive impact of foliar fertilization was detected on the content of photosynthetic pigments (a and b) at solely UV-B radiation effect than at combined effect of investigated factors, when significant changes were detected only in individual cases.
