“…Moreover, seed coated with the highest dose of Zn 5 g/kg seed had a deleterious effect on seed emergence and seedling growth for both varieties, especially in Altındane variety. Nevertheless, previous studies have noticed the same results reported by Dirginčiutė-Volodkienė and Pečiulytė (2011) and Rehman and Farooq (2016), where that accumulation Zn at high concentration may induce Zn toxicity, which may affect plant growth.…”

“…As indicated above, coated seed with 1.5 g Zn/kg seed had shown a slightly improvement in seed germination when compared to other concentrations and untreated seeds. Rehman and Farooq (2016) pointed out seed coated with Zn improves the seedling weight due to better root and shoot growth. Similarly, Zn coated seed make the nutrient available during the early establishment phase of seed germination and that leaded to faster the seedling growth (Taylor and Harman, 1990).…”

“…However, seed coating has effectively improved production of many crops like barley (Zeļonka et al, 2005) and rice (Tavares et al, 2012). In wheat seed coating with Zn, seed germination, seedling growth and tissue Zn content increases in comparison with uncoated seeds (Rehman and Farooq, 2016). There is limited information to the quantity of Zn fertilizers that can be applied effectively to seeds without injury to the germination seeds.…”

In this study, the effect of seeds priming (2.5 and 5 mM) and coating (1.5, 2.5 and 5 g Zn/kg seeds) on early growth stages of two wheat varieties showing difference for their seed Zn contents (Imam with average 29 mg/kg Zn and Altındane 25.5 mg/kg Zn) on germination and seedling growth parameters were determined under controlled-growth chamber conditions 20-25°C and 70% RH. In each treatment, 25 seeds were placed into Petri dishes to determine seed germination and sown into pots containing 700 g alluvial soil with low Zn content to monitor seedling growth for 21 days using three replications. The results revealed that seed priming with Zn, particularly high dose (5 mM) had relatively positive impact on seed germination, mean germination time and seedling growth parameters when compared with low Zn dose (2.5 mM) and hydropriming in both two wheat varieties. Seed coating with Zn, particularly with low Zn concentration (1.5 g Zn/kg seeds) and in Altındane with less Zn content, has shown good respond and improved seed germination parameters in comparison with untreated seeds for both wheat varieties. In conclusion, Zn seed priming and coating had more evident effects on germination and seedling growth parameters in variety with low Zn content compared with high one. The lowest concentration of seed coated with Zn of 1.5 g Zn/kg seeds had positive impact on wheat seedlings growth as well as it has low cost and safe to prevent of environment pollution.

“…Zinc fertilization through either method (soil, leaf, or seed treatments) is aimed to enhance the plant Zn uptake (Farooq et al, 2012;Rehman and Farooq, 2016;Rehman et al, 2018b,c). In Pakistan, the agronomic biofortification approach has been successful in improving the grain Zn concentration, crop productivity, and profitability (Tables 1, 2; Rehman et al, 2018a,b,d;Ullah et al, 2019Ullah et al, , 2020c).…”

“…However, recently, the research on legumes (chickpea and lentil) biofortification has also got attention (Rasheed et al, 2020;Ullah et al, 2020a,c,d,e). Farooq and colleagues have optimized several seed treatments (seed coating and seed priming) protocols for micronutrients delivery in rice, wheat, and chickpea along with soil and foliar fertilization in both Laboratory and field environments (Rehman et al, 2015(Rehman et al, , 2018bRehman and Farooq, 2016;Ullah et al, 2019Ullah et al, , 2020a). The seed treatments along with foliar and soil Zn application proved effective in enhancing the productivity and grain Zn concentration in tested crops.…”

Micronutrient malnutrition (e.g., zinc) is one of the major causes of human disease burden in the developing world. Zinc (Zn) deficiency is highly prevalent in the Pakistani population (22.1%), particularly in women and children (under 5 years) due to low dietary Zn intake. In Pakistan, wheat is the primary staple food and is poor in bioavailable Zn. However, the number of malnourished populations has decreased over the last decade due to multiplied public awareness, accelerated use of Zn fertilizers (particularly in wheat and rice), initiation of several national/international research initiatives focusing on Zn biofortification in staple crops and availability of supplements and Zn fortified meals merchandise, nonetheless a large number of people are facing Zn or other micronutrient deficiencies in the country. There are few reports highlighting the significant increase in daily dietary Zn uptake in population consuming biofortified wheat (Zincol-2016) flour; indicating the positive prospect of biofortification interventions up scaling in lowering the risk of dietary Zn deficiency in rural and marginalized communities. Zinc fertilizer strategy has not only helped in enhancing the grain Zn concentration, but it also helped in improving crop yield with high economic return. In addition, Zn biofortified seeds have exhibited strong inherent ability to withstand abiotic stresses and produce higher grain yield under diverse climatic conditions. However, there are many constraints (soil, environment, genetic diversity, antinutrients concentration, socioeconomic factors etc.) that hinder the success of biofortification interventions. This review highlights the status of Zn deficiency in Pakistan, the success of agronomic and genetic biofortification interventions. It also discusses the economics of agronomic biofortification and cost effectiveness of Zn fertilization in field conditions in Pakistan and the potential of Zn biofortified seeds against abiotic stresses. Furthermore, it also highlights the constraints which limit the sustainability of biofortification interventions.

The present study is carried out to establish the biofortification of zinc in potato (Solanum tuberosum L.) and tomato (Solanum lycopersicum L.) plants through the application of zinc oxide nanoparticles (ZnONPs). The mycogenic ZnONPs are synthesized by using Aspergillus flavus biomass and characterized to ascertain the size, shape, and concentration of synthesized nanoparticles. The ZnONPs are applied by foliar spray to the field-grown potato and tomato crops and the biofortification level is recorded by Atomic Absorption Spectroscopy (AAS). A nanotoxicity assessment is done by comparing the amount of cell death and accumulation of reactive oxygen species (ROS) in control and ZnONPs treated plants. The AAS analysis reveals significant accumulation of the zinc in leaves of potato plants but insignificant accumulation is observed in the tubers. However, a significant accumulation of zinc is observed in the leaves and fruits of the tomato plants (p ≤ 0.05). The nanotoxicity evaluation studies show comparable and statistically insignificant toxicity in control plants as compared to plants treated with ZnONPs. The study concludes that biofortification through the means of ZnONPs is a cost-effective and eco-friendly approach that can be used as an alternative to the hazardous chemical zinc fertilizers.
