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 ZnSO4,
150 g Fe.ha-1 as Fe2O3, 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.
