Effect of foliar application of Zn and Fe on wheat yield and quality

AFRICAN JOURNAL OF BIOTECHNOLOGY (Impact Factor: 0.57). 01/2010; 8(24):6795-6798. DOI: 10.4314/ajb.v8i24.68671

ABSTRACT

Intensive and multiple cropping, cultivations of crop varieties with heavy nutrient requirement and unbalanced use of chemical fertilizers especially nitrogen and phosphorus fertilizers reduced quality of grain production and the appearance of micronutrient deficiency in crops. A field experiment was conducted on clay-loam soil in Moghan region during 2007-2008 to investigate the effect of foliar application of zinc and iron on wheat yield and quality at tillering and heading stage. The experimental design was a randomized complete block design with three replicates. The SAS software package was used to analyze all the data and means were separated by the least significant difference (LSD) test at P< 0.01. The treatments were control (no Zn and Fe Application), 150 g Zn.ha -1 as ZnSO 4 , 150 g Fe.ha -1 as Fe 2 O 3 , and a combination of both Zn and Fe. In this study, parameters such as wheat grain yield, seed-Zn and Fe concentration were evaluated. Results showed that foliar application of Zn and Fe increased seed yield and its quality compared with control. Among treatments, application of (Fe + Zn) obtained highest seed yield and quality.

    • "Similarly, very low increase in grain zinc concentration (up to 40%) was observed after soil application of zinc fertilizer in maize (Kanwal and others 2010). Foliar application of zinc, besides influencing grain zinc concentration, could also increase iron concentration in wheat, rice, and maize grains (Fang and others 2008; Habib 2009; Aref 2010; Zeidan and others 2010), and reduce cadmium toxicity and accumulation in cereals grown "

    ABSTRACT: Iron and zinc are 2 important nutrients in the human diet. Their deficiencies in humans lead to a variety of health-related problems. Iron and zinc biofortification of cereals is considered a cost-effective solution to overcome the malnutrition of these minerals. Biofortification aims at either increasing accumulation of these minerals in edible parts, endosperm, or to increase their bioavailability. Iron and zinc fertilization management positively influence their accumulation in cereal grains. Regarding genetic strategies, quantitative genetic studies show the existence of ample variation for iron and zinc accumulation as well as inhibitors or promoters of their bioavailability in cereal grains. However, the genes underlying this variation have rarely been identified and never used in breeding programs. Genetically modified cereals developed by modulation of genes involved in iron and zinc homeostasis, or genes influencing bioavailability, have shown promising results. However, iron and zinc concentration were quantified in the whole grains during most of the studies, whereas a significant proportion of them is lost during milling. This makes it difficult to realistically assess the effectiveness of the different strategies. Moreover, modifications in the accumulation of toxic elements, like cadmium and arsenic, that are of concern for food safety are rarely determined. Trials in living organisms with iron- and zinc-biofortified cereals also remain to be undertaken. This review focuses on the common challenges and their possible solutions related to agronomic as well as genetic iron and zinc biofortification of cereals.

    • "It was concluded that application of nutrients through foliar sprays increased the seed yield of soybean (Haq and Mallarino, 2000). Recently, Habib (2009) confirmed that foliar application of Fe and Zn increased the seed yield in wheat. Moreover, they concluded that protein contents increased with increasing the Fe levels in the treatments. "
