“…This resulted in increase in plant height, leaf area index that helped in increasing the photosynthetic rate of plant, which in turn helped in formation of tillers. Above results were in thorough agreement with results of scientists like Sandhu et al [19], Ravikiran and Reddy [24] and Singh and Sharma [20].…”

“…Organic matter and ash content also showed non-significant effect on application of Zn at both the locations. [19]. The increase in number of tillers per plant at 60 DAS and 90 DAS was recorded with T3 (soil Zn 25 kg/ha + 0.5% foliar Zn at 60 DAS), and this might be because of superiority of ZnSO 4 in sustaining high Zn content in the soil rhizosphere.…”

The availability of poor quality fodders for livestock feeding is a major hurdle for the dairy industry in South Asia. The low content of Zn in fodders, leads to its malnutrition in animals. In fodders, Zn facilitates protein synthesis, gene expressions, energy production and involves in various metabolic activities of plants, animals and humans. To achieve these objectives, multi-location field trials were conducted on enrichment of oats fodder with Zn through bio-fortification. The experiment consists of eight different treatment combinations for enrichment of oats fodder with Zn including control, soil and soil plus foliar application of Zn at different stages of plant growth. The results of the study reported that soil application of Zn at the rate of 25 kg/ha and soil + foliar application of Zn at 0.5% at 60 days after sowing (DAS) (jointing stage), 90 DAS (booting stage) and both 60 DAS and 90 DAS showed improvement in plant growth parameters. The results further reported that foliar application of Zn at the rate of 0.5% at 60 DAS, 90 DAS, both 60 DAS and 90 DAS reported significant increase in biomass yield and fodder quality. Integrated application of Zn at 25 kg/ha in soil along with foliar Zn at the rate of 0.5% at 60 DAS and 90 DAS showed maximum Zn enrichment, green fodder yield, dry fodder yield, plant height, and Zn accumulation in oats fodder as compared to other treatments of Zn application. These treatments of Zn application through integrated mode also reported significant improvement in fodder quality with maximum crude protein (CP) and crude protein yield (CPY) while neutral detergent fiber (NDF), acid detergent fiber (ADF), ash content and organic matter showed a non-significant effect. Thus, the results of experimental study concluded that soil and foliar application of Zn at 25 kg/ha and 0.5% Zn, respectively, at 60 DAS and 90 DAS enhanced the growth, yield and quality of oats fodder which will certainly improve livestock production through bio-fortification.

“…Additionally, foliar-applied Zn and Mn enhance the crop yield including wheat, rice and barley [60]. In oats fodder crop, foliar-applied Cu at 0.2% at 60 and 90 days of sowing enhanced maximum Cu concentration and crude protein yield due to increased Cu uptake over control [47]. In another report, foliar-applied Fe improved the yield and Fe concentration along with other digestibility parameters in teosinte.…”

Globally, many developing countries are facing silent epidemics of nutritional deficiencies in human beings and animals. The lack of diversity in diet, i.e., cereal-based crops deficient in mineral nutrients is an additional threat to nutritional quality. The present review accounts for the significance of biofortification as a process to enhance the productivity of crops and also an agricultural solution to address the issues of nutritional security. In this endeavor, different innovative and specific biofortification approaches have been discussed for nutrient enrichment of field crops including cereals, pulses, oilseeds and fodder crops. The agronomic approach increases the micronutrient density in crops with soil and foliar application of fertilizers including amendments. The biofortification through conventional breeding approach includes the selection of efficient genotypes, practicing crossing of plants with desirable nutritional traits without sacrificing agricultural and economic productivity. However, the transgenic/biotechnological approach involves the synthesis of transgenes for micronutrient re-translocation between tissues to enhance their bioavailability. Soil microorganisms enhance nutrient content in the rhizosphere through diverse mechanisms such as synthesis, mobilization, transformations and siderophore production which accumulate more minerals in plants. Different sources of micronutrients viz. mineral solutions, chelates and nanoparticles play a pivotal role in the process of biofortification as it regulates the absorption rates and mechanisms in plants. Apart from the quality parameters, biofortification also improved the crop yield to alleviate hidden hunger thus proving to be a sustainable and cost-effective approach. Thus, this review article conveys a message for researchers about the adequate potential of biofortification to increase crop productivity and nourish the crop with additional nutrient content to provide food security and nutritional quality to humans and livestock.

Agronomic biofortification of forage crops with zinc and copper for enhancing nutritive potential: a systematic review

Many developing countries are facing a silent increase in deficiency of micronutrients in forage crops that results in decreased levels of essential nutrients in animals. Micronutrients are essential not only for basic metabolic processes of forage crops but also for sustaining animal health. Forage productivity and quality are severely affected by soil micronutrients deficiencies, especially zinc and copper. This review summarizes the literature highlighting the significance of different methodologies used to increase the biomass and quality of forage so as to enhance the micronutrient content of the forage crops through biofortification. Biofortification is a promising and sustainable agriculture‐based strategy to reduce micronutrient deficiency in crops. The experiments and trials conducted at different locations of the world showed that copper and zinc concentrations in animal fodders can be enhanced through the process of foliar application. Additionally, agronomic biofortification showed more promising results, and thus is an outstanding, fast, and cost‐effective technique for the immediate enrichment of forage in order to overcome malnutrition in animals. © 2022 Society of Chemical Industry.
