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


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. "

    ABSTRACT: Background: In order to investigate the effect of different concentrations of iron chelate Nano fertilizer and Fe-EDDHA on Morphological characteristics and antioxidant enzymes activity of green gram, a pot experiment was with three replications. Objective: The treatments in the experiment were four concentrations of iron chelate (10, 50, 100 and 250 ppm) and four concentrations of nano-iron chelate (10, 50, 100 and 250 ppm) and an untreated control. Analysis of variance (ANOVA) was performed between treatment samples. The information was analyzed using SPSS computer software. Means compared by multiple range Tukey test and a 95% significance level (p < 0.05) was employed for all comparisons. Results: Results showed that growth parameters increased in plants treated with Fe-EDDHA (S50 ppm) and nano Fe chelate with (N10 ppm); and exposure of mung bean to 50 ppm Fe-EDDHA indicated the greatest shoot fresh weight, shoot dry weight were respectively (by 71.67 % and 71.97 % more than control group) related to other treatments. Increasing nanoparticles concentration above 10 ppm reduced shoot fresh weight, shoot dry weight. It has not found any significant effects by Fe-EDDHA and nano iron chelate on elongation of shoot and root of mung bean. Application of 50 ppm concentration of nano iron chelate increased shoot length by 18.43% in comparison to the control group, also 50 ppm concentration of Fe-EDDHA increased shoot length by 30.82% in comparison to the control group; while 50 ppm nano iron chelate in comparison to the 50 ppm iron chelate was not significant. The highest root biomass was achieved from concentration of 50 ppm Fe-EDDHA, but an increased concentrations of nano iron chelate significantly reduced root weight. The antioxidant enzymes activity(catalaz) in the Fe-EDDHA treatments was more than nano Fe treatments while enzyme ascorbat peroxidaz in the Fe-EDDHA treatments to 100 ppm was increased but in nano-iron chelate treatments to 100 ppm was decreased. Moreover, nano iron chelate resulted in the reduction of protein amounts in comparison with Fe-EDDHA treatments but was significant compared to S50 ppm, S100 ppm and S250 ppm. Chlorophyll b treated with 50 ppm nano iron chelates compared to all other treatments had the highest value. Chlorophyll a and total chlorophyll (a + b) nano-iron chelate treatment was lower compared with Fe-EDDHA treatments. Conclusion: The results of this study suggest that Due to the increase in chlorophyll b And ultimately increase the mungbean plant photosynthesis by nano-iron chelate compared with Fe-EDDHA And also due to the reasonable price and low nano-iron chelate than ordinary Fe-EDDHA Recommended for nano-iron chelate used in place of Fe-EDDHA. The aim of this study was to compare the two iron chelated fertilizer, and nano-iron chelated fertilizer in different concentrations on some physiological and biochemical responses of plants mung bean (Vigna radiata). In this study, the effects of nano-iron chelated fertilizer and iron chelated fertilizer were determined on growth parameters, photosynthetic pigments, leaf protein content and some of the activity antioxidant enzymes in the leaves.
