“…As reported by Graham [4], every second, one person dies of disease related to diet. Moreover, Fe deficiency affects more than two billion individuals, or one in three people globally [7,8], while about 30% of people in developing countries and 10% of Americans and Canadians are Zn deficient [9]. The World Health Organization estimates that approximately 25% of the world's population suffers from anemia [10], and that Fe deficiency anemia led to the loss of over 46,000 disability-adjusted life years (DALYs) in 2010 alone [11].…”

Wheat (Triticum aestivum L.) is one of the main foods globally. Nutrition problems associated with Zinc and Iron deficiency affect more than two billion individuals. Biofortification is a strategy believed to be sustainable, economical and easily implemented. This study evaluated the effect of combined Zn and Fe applied as foliar fertilizer to winter wheat on grain yield, quality, Zn and Fe concentration in the grains. Results showed that treatments containing high Fe increased the yield. Grain crude fat content remained unaffected. Crude fiber was enhanced up to three-fold by 60% Zn + 40% Fe5.5 (5.5 kg ha−1 of 60% Zn + 40% Fe). Moreover, 80% Zn + 20% Fe5.5 (5.5 kg ha−1 of 80% Zn + 20% Fe) was the best combination for increasing crude protein. Zinc applied alone enhanced Zn concentration in grain. In addition, Fe was slightly improved by an application of Zn and Fe in the first year, but a greater increase was observed in the second year, where 100% Fe13 (13 kg ha−1 of 100% Fe) was the best in improving Fe in grain. Foliar application of Zn and Fe is a practical approach to increase Zn and Fe concentration, and to improve the quality of wheat grains.

“…Erenoglu [9] demonstrated that biofortification of food cultivation must take into account the key role of nitrogen in Zn uptake and accumulation. The role of nitrogen in facilitating the uptake, transportation, translocation and deposit of microelements, in particular of Zn in cereal grain, has been thoroughly studied [25].The yield and quality if wheat grain depend on the characteristics of the cultivar, applied agrotechnics and environmental factors [1,26]. The cultivar also dictates wheat's technological value.…”

Effect of Habitat and Foliar Fertilization with K, Zn and Mn on Winter Wheat Grain and Baking Qualities

et al. 2020

Cereal monoculture causes a series of unfavorable changes in field habitat, for example a decrease in technological quality and yield. This system can lead to a shortage of microelements in the diet of poor communities. Moreover, breeding of highly productive plants caused a significant "dilution effect" of the necessary nutrients, such as Zn and Fe. The aim of this work was to determine the effect of two strategies: crop rotation (after rapeseed and many years of monoculture of Galega orientalis Lam.) and foliar fertilization with microelements on the yield, yield elements, physical quality, and farinograph characteristics of winter wheat grain and flour. Results showed that pre-crop preparation and cultivation year have the highest effect on yield, yield components, and qualitative and farinographic characteristics of winter wheat. Foliar additional feeding favorably affected the yield and its components, although the particular fertilization treatment did not significantly increase the yield. Grain quality, its physical characteristics and the rheological parameters of flour were strongly modified by habitat conditions, including weather conditions. Dough obtained from wheat grown after galega showed significantly higher water absorption and prolonged consistency.Zn content. Its consumption in rural areas will probably increase to over 70%, which could lead to an increase in the micronutrient shortage in communities with poor resources [10]. Cereals provide up to 52% of the daily requirement for Zn. Biofortification is a process of plant growth that generates high microelement content through traditional breeding or modern biotechnology. It has been stated that Zn concentration in intensively cultivated soils oscillates between 20 and 35 mg kg −1 , and may be significantly below that level when wheat is grown in soils poor in zinc [11,12]. In the case of wheat grain, Zn bioavailability reaches about 25% of that amount, which is related to the presence of anti-nutritional factors, such as phitynians and the lack of promoter substances in the grain [13].Approximately 30% of the population in developing countries, and about 10% of Americans and Canadians, suffer from Zn shortages [14]. It is estimated that 17.3% of the entire world population is at risk of inadequate Zn consumption, and Zn shortage leads to an estimated annual death rate of 433,000 children under the age of 5 [15]. It was recently found that in Great Britain, Zn consumption in about a quarter of teenagers is lower than the Lower Reference Nutrient Intake (LRNI).There are numerous strategies for improving the intake of micronutrients with plant-based diets and bolstering the condition of plant nourishment in order for microelements to reach food, such as rice diversification, mineral supplementation, enrichment after harvest and bio-diversification [16]. Plant breeding (for example genetic biofortification) and Zn fertilizer application (for example agronomic biofortification) are two important agricultural tools for improving Zn concentration in ...

“…It was observed that status of plant mineral nutrient plays an important role in improving resistance against water stress condition. Inoculation of wheat seed with PGPB has positive role on leaf nitrogen, phosphorus, potassium, chlorophyll and relative water contents [7,22]. The conclusion made that PGPB coated fertilizer application was effective in improving the morphological and biochemical parameters of wheat in water stress condition.…”

“…In areas where cropping systems are intensive, supplementing soil nutrients by use of chemical fertilizers has attained inevitable importance for obtaining optimum yield of crops [6]. However, their utilization efficiency remains low, due to losses through volatilization, denitrification, leaching and ultimately fixed with clay particle and become unavailable to crop plants [7]. Among various techniques, exogenous application of silicon [6], potassium (K + ), salicylic acid (SA), glycinebetaine (GB) and proline as major organic osmolytes [7,8] are believed to play a vital role against various a biotic and biotic stresses such as drought, salinity, extreme temperatures, UV radiation and heavy metals and pest attack.…”

Water stress is a major threat against wheat growth. The effects of induced stress can be reduced after by fortified fertilizer treated by Plant Growth Promoting Bacteria (PGPB). With the objective to combat the water stress, two different experiments under net house and field condition were conducted. Three different states of fertilizer [F0: Control (no fertilizer application); F1: PGPB-coated fertilizer (urea and phosphorous) &F2: uncoated fertilizer (urea and phosphorous)]. In a pot experiment, wheat plants were applied fertilizer in raised and wellwatered (60 percent of field capacity) and water stressed (40 percent of field capacity) conditions in soil filled pots. In experiment-II (field study), similar treatments of fertilizer were revised, but well-watered and water stress treatments/plots were irrigated for 60 seconds and 30 seconds respectively. At maturity plants were harvested and various morphological (number of tillers/plant, number of spikelet/spike, number of grains/spike, weight of grains, biological yield, economic yield and harvest index) and biochemical parameters (leaf nitrogen, phosphorous & potassium contents) of crop were recorded. Leaf chlorophyll and relative water contents of crop were also measured 60 days after sowing. In this study, it was demonstrated that the water stress adversely affected all the above mentioned parameters. The PGPB coated fertilizer application in wheat significantly increased (p<0.01 for pot and p<0.05 for field study) morphological and biochemical parameters in the presence and absence of water stress both under net house and field conditions. We can conclude from these findings that application of PGPB coated fertilizer is valuable strategy to mitigate the water stress impact on wheat with improved yield.
