Abstract
A farm experiment with corn plant grown on Zn and B deficient soil was conducted to study the effect of Zn and B interaction on the concentration and total uptake of Fe and Mn in corn grain during 2009 at Fars Province, Iran. Treatments including five levels of Zn (0, 8, 16 and 24 kg ha -1 and Zn foliar spray) and four levels of B (0, 3, and 6 kg ha -1 and B foliar spray) in a completely randomized block design were set up. The findings showed that the effects of Zn and B and the interaction of Zn and B on the Fe concentration in the grain were insignificant. The effect of Zn on Fe uptake in the grain was insignificant and among different levels of B, only application of 3 kg ha -1 B increased Fe uptake in the grain. Boron use had no effect on Fe uptake in the grain in any level. Only at high level of B (6 kg ha -1 B), application of 16 kg ha -1 Zn increased Fe uptake in the grain. Boron use and Zn and B interaction was not significant on Mn concentration in the grain. Application of 24 kg ha -1 Zn increased Mn concentration in the grain from 3.67 to 4.75 mg kg -1 but other levels of Zn had no effect. Application of Zn to the soil and spraying it increased Mn uptake in the grain. Application of B to the soil increased Mn uptake in the grain but B spraying had no effect on it. Application of B at low levels and Zn spraying had no effect on Mn uptake in the grain but at higher Zn levels (16 and 24 kg ha -1 Zn) increased Mn uptake in the grain. Application of Zn at zero and 6 kg ha
