SUMMARYSelenium (Se) is an essential micronutrient for humans, yet its dietary intake is low, mostly due to the low bioavailability in soils and therefore in edible plant tissues. To overcome Se deficiency, the breeding approach (i.e., genetic biofortification), namely in rice, is largely dependent on available Se pools. To ensure the success of genetic biofortification with Se, agronomic biofortification can be accomplished through foliar Se application. Considering this background, the main hypothesis of this work was centered in the foliar application of Se to attain agronomic biofortification of rice crops. This study also aimed to assess the full potential for increasing grain Se concentrations during rice filling, as well as the types of nutrients deposition. An experimental design applying two foliar fertilizers (sodium selenite and sodium selenate) was developed. As test systems, four rice genotypes (Ariete, Albatros, OP1105 and OP1109) were used and the kinetics of micro- and macro-nutrients accumulation and deposition were assessed. Biofortification was performed in field trials for two years with foliar fertilization ranging between 0 and 300 g Se ha−1. At the end of the plant cycle, selenite applications triggered 427- to 884-fold increases in grain Se concentrations among rice genotypes (Albatros > OP1105 > OP1109 > Ariete). The application of selenate also prompted 128- to 347-fold increases in grain Se concentrations in rice crops (Albatros > OP1105 > Ariete > OP1109). Regardless of the foliar fertilizer applied, Se deposition among genotypes occurred throughout the grain without relevant inhibitory effects on yields. In each genotype, micro and macronutrients varied among crop tissues.

“…Foliar application of nutrients is an important crop management strategy to maximize crop yields and concentrations of micronutrients in edible parts. Several studies have demonstrated that foliar application of micronutrients, including Zn and Fe, showed good behavior in increasing their concentration in wheat grain [27,[48][49][50][51][52]. However, little is known about the effect of combined Zn and Fe on the quality of this wheat grain.…”

Winter Wheat Grain Quality, Zinc and Iron Concentration Affected by a Combined Foliar Spray of Zinc and Iron Fertilizers

et al. 2019

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.

Nitrogen fertilization combined with microelements is an effective way to provide nutrients to plants, which are essential for obtaining high-value crops. The aim of this study was to evaluate two N fertilizer rates (150 and 200 kg ha-1) and four Mn fertilizer rates (0.0, 0.5, 1.0, and 1.5 kg Mn ha-1) on the N, Mn, Zn, Cu, and Fe content and composition of fatty acids in winter wheat (Triticum aestivum L.) grain. An increase in the N fertilizer rate increased (12.7%) the Mn content and decreased (10%) the Cu content of wheat grain. Regardless of N fertilization, foliar application of Mn at 1.5 kg ha-1 contributed to the highest Zn (28.4 mg kg-1) and Fe (58.4 mg kg-1) content in the grain. In an analysis of lipid fractions, the highest value of the coefficient of variation was recorded for C18:0 (16.3%-low variation). Nitrogen and Mn fertilization were most strongly correlated with the Mn content of grain (r = 0.356, r = 0.391, respectively). The 200 kg N ha-1 treatments combined with 1.0 kg ha-1 Mn and 150 kg ha-1 N without Mn were correlated with the content of C:18:0, C18:1c11, C18:1c9, and monounsaturated fatty acids in the grain. The application of 200 kg ha-1 N with 1.5 kg ha-1 Mn was correlated with the Fe, Zn, and Mn content of the grain. The remaining fertilization treatments were correlated with the content of C18:3, C18:2, polyunsaturated fatty acids (PUFA), and the C18:2/C18:3 ratio in the grain. Results indicated that the application of 200 kg ha-1 N beneficially affected the PUFA content in the winter wheat grain and can therefore be used to obtain raw material with increased nutritional value. The human organism does not synthesize PUFA, so they must be taken with food (or supplements); winter wheat grain can be a good source because it contains more than 60% PUFA.
