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 "

    • "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. "

    • "The synergistic behavior of Zn and Cd at higher concentrations of Zn (0.6 % Zn SO 4 ) is attributed to the decreased antioxidant enzyme activity in plants supplemented with this concentration of Zn. The resulting increase in the concentration of ROS can cause membrane damage that, in turn, increases the Cd translocation from shoots to grains (Habib 2009). Cherif et al. (2011) reported that as compared to higher Zn levels (100 and 150 lM), low levels of Zn (50 lM) significantly decreased Cd-induced oxidative stress, as indicated by the decrease in the level of thiobarbituric acid-reactive substances and the activities of antioxidant enzymes in tomato plants.

    ABSTRACT: Cadmium (Cd) is a highly toxic heavy metal and its presence in soil is of great concern due to the danger of its entry into the food chain. Among many others, proper plant nutrition is an economic and practicable strategy for minimizing the damage to plants from Cd and to decrease Cd accumulation in edible plant parts. The study was carried out to compare the effectiveness of soil and foliar applications of zinc (Zn) to minimize Cd accumulation in wheat grains. The results revealed that the exposure of plants to Cd decreased plant growth and increased Cd concentration in the shoots and grains of wheat, when compared with unexposed plants. Foliar application of 0.3 % zinc sulfate solution effectively decreased Cd concentration in wheat grains. Foliar application of Zn at a suitable concentration can effectively ameliorate the adverse effects of Cd exposure and decrease the grain Cd concentration of wheat grown in Cd-contaminated soil.
