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

AFRICAN JOURNAL OF BIOTECHNOLOGY (Impact Factor: 0.57). 01/2010; 8:6795-6798.

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.

    ABSTRACT: A field experiment was conducted in two successive seasons (2009/2010 and 2010/2011) at Shbeen El Knatr, El Qualubia, Governorate to study the effect of farmyard manure (FYM) at (0, 10 and 20 m 3 fed -1) soil application of humic acid (0, 1 and 2%) and 0.5% zinc as Zinc sulphate foliar application on yield and chemical composition of wheat. Results indicated that, application of FYM and humic acid within all tested rates, resulted in significant increase in grains, weight of 100 grain, biological yield and straw yields of wheat compared to control treatment. Application of the FYM at the rate of 20 m 3 fed -1 + 0.5% Zn produced the highest values of grain yield, weight of 100 g grains, as well as straw yield of wheat plants compared with other applied treatments. The second best treatment was the application of 2% Humic acid combined with 0.05% Zn as foliar application followed by soil application of the FYM at the rate of 10 m 3 fed -1 . Application of FYM at the rate of 20 m 3 fed -1 alone were similar in their effects on grain yield production as compare to application of 2% Humic acid combined with 0.05% Zn and the difference between them were insignificant in most traits. Application FYM significantly increased nitrogen and phosphorus content and uptake in grain and straw over humic acid application. Moreover, application of FYM, or humic acid combined with zinc had significant effect on Fe, Mn and Zn uptake as compared with the control treatment. Highly significant and positive correlations were observed between grain and straw wheat yield and macro and micronutrients. Results revealed that fertilizing of wheat plants with FYM or Humic acid combined with Zinc is important to increase the yield production and nutrients uptake by wheat plants.

    ABSTRACT: The aims of this study was evaluated the effectiveness of different fertilizer treatment on yield and yield components of maize cultivar single cross 704. This study was carried in the Research Farms of Faculty Agricultural, Islamic Azad University in Saveh branch by using randomized complete block design (RCBD) with 4 replications and 10 different fertilizer treatments was applied as foliar spray and soil application. In this study some characters such as plant height, grain yield and yield components included number of grain rows per ear, number of grians per row, ear weight and ear diameter were measured. All measured traits were influence of different fertilizer treatment, so that the highest grain yield was observed in M treatment (foliar spray of 2 complete fertilizer in stem and cob elongation stage) with average yield 10649kghaG , M (foliar spray of 1 1 complete fertilizer in stem elongation stage) with average yield 10421kghaG and Z (foliar spray of Zn fertilizer 1 2 in cob elongation stage) with average yield 9846kghaG .
