“…The manganese foliar application might improve the grain yield; as Mn foliar fertilization at the anthesis stage efficiently translocates the Mn towards reproductive parts, and then accumulates in grains [86,87]. In addition, the foliar application of Mn resulted in absorption in the leaf epidermis, and after remobilization, it was transported into developing grains via xylem [88].…”

Manganese is an important essential micronutrient, and its deficiency causes latent health issues in humans. Agronomic biofortification can promisingly improve the plant nutrient concentration without changing the genetic makeup of plants. This study was designed to assess the best method of Mn application to enhance productivity and grain Mn contents under conventional tillage (CT) and no tillage (NT) systems. Manganese was delivered through seed coating (250-mg kg−1 seed), osmopriming (0.1-M Mn solution), soil application (1 kg ha−1), and foliar application (0.25-M Mn solution). A general control with no seed Mn application was included, whereas hydropriming and water spray were used as positive control treatments for Mn seed priming and Mn foliar spray, respectively. No tillage had a higher total soil porosity (9%), soil organic carbon (16%), soil microbial biomass carbon (4%), nitrogen (2%), and soil nutrients in the CT system. Manganese nutrition through various methods significantly enhanced the yield, grain biofortification, and net benefits for CT and NT systems. Averaged across two years, the maximum improvement in grain productivity was recorded with osmopriming (28%) followed by foliar application (26%). The highest grain Mn concentration (29% over no application) was recorded with Mn foliar applications under both tillage systems. Moreover, the highest economic returns and marginal net benefits were recorded with osmopriming. To improve the wheat production, profitability, and grain Mn concentration, Mn application through priming and foliar application may be opted.

“…In humans, Mn is needed for reproduction, carbohydrate and lipid metabolism, and neurological functioning [120]. Crops grown for food production are the primary source of Mn for humans, providing over 50% of our dietary intake [118,121]. Although Mn deficiency has not yet been observed in the human population [120], it occurs in c. 10% of arable soils worldwide; global fruit, cereal, and certain vegetable crops are all prone to Mn deficiency, which causes interveinal leaf chlorosis and necrotic spotting, reduced tillering, the inhibition of root growth, stunted plant growth and suboptimal nutrient assimilation [9,25,118,121].…”

“…However, Mn availability decreases at soil pH > 7.5 as it adsorbs strongly into various (hydr-)oxides, clay fractions, organic compounds, and calcium carbonate [25]. Consequently, Mn deficiency typically occurs in arable crops grown in calcareous or heavily limed soils [9,25,118,121]. However, even under alkaline conditions, Mn-containing organomineral and anionic complexes can remain relatively soluble and contribute to Mn availability for plants and microbes [25].…”

Soil micronutrients limit crop productivity in many regions worldwide, and micronutrient deficiencies affect over two billion people globally. Microbial biofertilizers could combat these issues by inoculating arable soils with microorganisms that mobilize micronutrients, increasing their availability to crop plants in an environmentally sustainable and cost-effective manner. However, the widespread application of biofertilizers is limited by complex micronutrient–microbe–plant interactions, which reduce their effectiveness under field conditions. Here, we review the current state of seven micronutrients in food production. We examine the mechanisms underpinning microbial micronutrient mobilization in natural ecosystems and synthesize the state-of-knowledge to improve our overall understanding of biofertilizers in food crop production. We demonstrate that, although soil micronutrient concentrations are strongly influenced by soil conditions, land management practices can also substantially affect micronutrient availability and uptake by plants. The effectiveness of biofertilizers varies, but several lines of evidence indicate substantial benefits in co-applying biofertilizers with conventional inorganic or organic fertilizers. Studies of micronutrient cycling in natural ecosystems provide examples of microbial taxa capable of mobilizing multiple micronutrients whilst withstanding harsh environmental conditions. Research into the mechanisms of microbial nutrient mobilization in natural ecosystems could, therefore, yield effective biofertilizers to improve crop nutrition under global changes.

“…To overcome the challenge of Zn deficiency, agronomic biofortification of Zn could be a possible solution (Zulfiqar, Hussain, et al., 2020; Zulfiqar, Maqsood, & Hussain, 2020), in which Zn can be applied through various methods including basal application, foliar spray, seed coating, and seed priming (Ullah, Farooq, & Hussain, 2019); however, variations exist among different methods regarding cost effectiveness and efficacy (Zulfiqar, Maqsood, Hussain, & Anwar‐ul‐Haq, 2020).…”

Zinc (Zn) deficiency is the most important abiotic factor limiting rice (Oryza sativa L.) productivity and also a nutritional disorder with adverse impacts on human health worldwide. The present study investigated the comparative effect of four Zn application methods: Zn seed coating (2 g Zn kg−1 seed), Zn seed priming (0.25 M Zn solution), basal application (10 kg ha−1), and Zn foliar spray (0.5% Zn solution) in improving the productivity and biofortification of rice under puddled transplanted (PudTR) and direct‐seeded rice (DSR) system. A general control with no Zn application was included, whereas hydro‐priming and foliar water application were used as positive control treatments for Zn seed priming and Zn foliar spray, respectively. Regardless of application methods, Zn nutrition significantly improved the yield and related traits and grain Zn concentration in both production systems. Averaged across 2 yr, the increase in grain yield under different Zn application treatments was in the order of seed priming (23%) > foliar application (18%) > basal application (18%) > seed coating (13%), compared with the control. However, grain Zn concentration was the highest with seed priming in PudTR (33% over control) and with basal application in DSR (45% over control). The maximum net benefits were obtained through Zn seed priming in both production systems. In conclusion, Zn seed priming improved the yield and was the most cost‐effective method in PudTR and DSR system.
