Abstract
Zinc (Zn) and boron (B) deficiency is one of the most widespread micro nutritional disorders in crops, and occurs predominantly in calcareous soils of arid and semiarid regions. A field experiment with maize plant grown on Zn and B deficient soil was carried out in a calcareous soil at Fars Province, Iran. This work aimed to study the interaction effect of Zn and B on the concentration of Zn and B in the maize leaf during 2008. Treatments included five levels of Zn (0, 8, 16 and 24 kg ha −1 Zn added to the soil and Zn foliar spray at 0.5 weight percent of zinc sulfate) and four levels of B (0, 3, and 6 kg ha −1 B added to the soil and B foliar spray at 0.3 weight percent of boric acid) in a completely randomized block design. The findings showed that application of Zn, B, and Zn−B interaction on the B concentration in the leaf was insignificant. Zinc spraying increased Zn concentration in the leaf but adding Zn to the soil had no significant effect on it. Presence of B prevented from the increase in Zn concentration in the leaf; that is, an antagonism was seen between the Zn and B. Boron application decreased leaf Zn content and this increase was not influenced by the amount of Zn. Zinc use at no presence B in the soil (zero B and B spraying levels) increased leaf Zn content.
