Abstract

Application of IRON (Fe) chelate is one of the most effective methods for correcting IRON deficiency in calcareous soils. However, its efficiency may decrease due to the antagonistic effect of Fe on some nutrients including MANGANESE (Mn).' An experiment was conducted in a loamy soil, low in available Fe (Fine-loamy, carbonatic, thermic, Typic Calcixerepts) in order to determine the effect of Fe on seed yield (SY) and chemical composition of 12 soybean [Glycine max (L.) Merril] genotypes under greenhouse conditions. Treatments consisted of a factorial arrangement of Fe rates (0, 2.5, and 5 mg kg-1 as FE-EDDHA) and 12 soybean genotypes. Results of current study showed that Fe application only increased SY of Black hack but decreased that of Wells and had no significant effects on other genotypes; therefore, it seems that top dry weight response to Fe is not an adequate criteria for predicting SY of soybean genotypes. Addition of Fe increased mean seed Fe:Mn ratio and seed Fe concentration and uptake but had no significant effect on those of copper (Cu). IRON application had no significant effect on mean zinc (Zn) or phosphorous (P) concentrations. IRON application increased mean Zn uptake but reduced Mn concentration and uptake and P:Fe ratio. Also, our previous results indicated that application of Fe decreased Mn concentration in all soybean genotypes shoot. A significant regression equation between applied Fe rates and seed Mn concentration was obtained (R2=0.60). IRON did not increase soybean genotypes seed yield probably due to antagonistic effect of Fe on Mn absorption and or translocation. Growing Fe-efficient soybean genotypes is an appropriate approach for Fe deficient calcareous soils.
