“…These observations are supported by previous studies, where siderophore producing bacteria including PsJN (which secrete hydroxamate-containing siderophore such as pyoverdin) often reported enhanced plant growth by facilitating Fe uptake and mediating plant tolerance against various abiotic stresses [13,54,55]. Moreover, biochar is known to play a critical role in iron biofortification of cereals in pH affected calcareous [22] as well as saline soils [56]. Biochar addition enhances nutrients availability to crops, increase water holding capacity of the soil and enhance microbial activity which might increase plant biomass accumulation under stressed conditions [57].…”

“…However, microbial-based and biochar-based iron biofortification offers more sustainable and cost-effective strategies to provide micronutrients (iron, zinc, etc.,) in developing countries. Moreover, iron biofortification of important agronomic crops like rice, wheat, and maize has been focused [21][22][23][24] but Fe biofortification of emerging food crop quinoa is hardly investigated. Here, we investigated the potential of plant growth-promoting bacterium B. phytofirmans PsJN and organic amendment (biochar) on the growth characters, yield parameters and iron biofortification potential of quinoa growing in iron-limited saline soil.…”

Iron-biofortification is a sustainable food-based approach to combat iron deficiency by increasing iron content and bioavailability in agronomic crops. Siderophore producing microbes offer a sustainable and low-cost way to increase iron supply in crops. Also, certain substances released from organic amendments act as iron-chelators which increase the solubility as well as the availability of iron to plants. Present study investigated the role of siderophore-producing endophytic bacteria and biochar on iron-fortification of a novel crop quinoa in iron-limited saline conditions. The surface-disinfected seeds of quinoa were inoculated with Burkholderia phytofirmans PsJN (CFU = 109) and sown in saline soil (EC 20 dS m−1) amended with biochar (1% w/w). Results revealed that biochar and PsJN particularly when applied together significantly enhanced plant growth, grain yield, and grain nutrient contents of quinoa. Strikingly, iron concentration in quinoa grains was increased up to 71% by the combined application of biochar and PsJN. Moreover, plant physiological parameters were also improved significantly by the integrated application. However, enzymatic/non-enzymatic antioxidants activities were decreased by integrated treatment thus ameliorated salinity stress. Our study suggests that integrated application of siderophore-producing bacteria and biochar could be a promising, sustainable and cost-effective strategy which is easily integratable into the existing farming practices to achieve food fortification with micronutrients in developing countries.

“…A few studies considered use of biochar and nutrients in plants relative to human health. For example, nutrient increases were due to use of a biochar feedstock with a high nutrient concentration (e.g., macroalgae from wastewater, in Roberts et al, 2015 ), or an enhanced increase in essential nutrients when biochar was applied with a concentrated source of nutrients such as Fe fertilizer ( Ramzani et al, 2016a , 2016b ) or biosolids ( Gartler et al, 2013 ). Ramzani et al (2017) applied only biochar and found increases in essential nutrients, but the biochar had been acidified with sulfur.…”

“…For example, acidified (with S) maize cob biochar increased the concentrations of Fe, K, Mn, and Zn, and to a lesser extent, Mg and Ca (in one case biochar decreased Ca), in quinoa seed for plants growing under different soil stress conditions (Ramzani et al, 2017). While eucalyptus twig biochar by itself had no effect on rice grain Fe concentration, the biochar did enhance the increase in concentrations of these nutrients when Fe fertilizer was also used to biofortify the crop with Fe (Ramzani et al, 2016a). In a study with biosolids and biosolids plus biochar (made from Pinus radiata chips) in combination, Gartler et al (2013) found increased extractable soil Zn concentrations and the concentrations of Zn in the edible portions of several crops, including lettuce leaves and carrot taproots.…”

Essential nutrient concentrations in crops can affect human health. While biochar has the potential as a soil amendment to improve crop yields, it may also affect the concentrations of nutrients such as Ca, Fe, K, Mg, Mn, and Zn in edible portions of crops. To better characterize effects of biochar on important human nutrients in food crops, we evaluated the effects of biochar on lettuce (Lactuca sativa L. cv. Black-Seeded Simpson) leaf and carrot [Daucus carota subsp. sativus (Hoffm.) Schübl. cv. Tendersweet] developing taproot nutrients. Plants were grown in pots in a greenhouse using sandy loam (Coxville, fine, kaolinitic, thermic Typic Paleaquults) and loamy sand (Norfolk, fine-loamy, kaolinitic, thermic Typic Kandiudults,) series soils, amended with biochar produced from four feedstocks: pine chips (PC), poultry litter (PL), swine solids (SS), and switchgrass (SG); and two blends of PC plus PL [PC/PL, 50%/50% (55) and 80%/20% (82) by weight]. Biochar was produced at 350, 500, and 700 °C from each feedstock. Lettuce leaf and carrot taproot total nutrient concentrations were determined by inductively coupled plasma analysis. Biochar (especially at least in part manure-based, i.e., PL, SS, 55, and 82 at nearly all temperatures) primarily decreased nutrient concentrations in lettuce leaves, with Ca, Mg, and Zn affected most. Carrot taproot nutrient concentrations also deceased, but to a lesser extent. Some biochars increased leaf or taproot nutrient concentrations, especially K. This study indicated that biochar can both decrease and increase leaf and taproot nutrient concentrations important for human health. Thus, potential effects on nutrients in plants should be carefully considered when biochar is used as a soil amendment with vegetable crops.

“…Plant breeding has made outstanding progress in increasing crop productivity in combination with developments in agricultural technologies. To achieve high-yield response, breeding efforts mainly focused upon development of high yielding input-responsive genotypes (Shivay and Prasad 2012;Ramzani et al 2016). By adopting innovative technologies and realizing potential yields of crop plants to attain complete food security, crop breeding is now at verge of transformation from food security to nutritional security (Ehsanullah et al 2015).…”

Both human and animals, for their nutritional requirements, mainly rely on the plant-based foods, which provide a wide range of nutrients. Minerals, proteins, vitamins are among the nutrients which are essential and need to be available in adequate amount in edible portion of the staple crops. Increasing nutritional content in staple crops either through agronomic biofortification or through conventional plant-breeding strategies continue to be a huge task for scientists around the globe. Although some success has been achieved in recent past, in most cases, we have fallen short of expected targets. To maximize the nutrient uptake and partitioning to different economic part of plants, scientists have employed and tailored several biofortification strategies. But in present agricultural and environmental concerns, these approaches are not much effective. Henceforth, we are highlighting the recent developments and promising aspects of microbial-assisted and genomic-assisted breeding as candidate biofortification approach, that have contributed significantly in increasing nutritional content in grains of different crops. The methods used to date to accomplish nutrient enrichment with recently emerging strategies that we believe could be the most promising and holistic approach for future biofortification program. Results are encouraging, but for future perspective, the existing knowledge about the strategies needs to be confined. Concerted scientific investment are required to widen up these biofortification strategies, so that it could play an important role in ensuring nutritional security of ever-growing population in growing agricultural and environmental constraints.
