Responses of Earlirose rice to iron, zinc, and BPDS when grown on calcareous soil

Journal Article · · Commun. Soil Sci. Plant Anal.; (United States)
The Earlirose cultivar of rice (Oryza sativa L.) grown in calcareous Hacienda loam soil was extremely Fe deficient. The Fe deficiency was corrected by premixing 40 ppM Fe (as FeSO/sub 4/) into the soil before transplanting plants. The Fe deficiency appeared to be induced by high plant levels of Cu and Mn. Addition of Zn (40 ppM as ZnSO/sub 4/) intensified the Fe deficiency. The Fe addition did not overcome the effect of the Zn. BPDS (bathophenanthroline disulfonate), a chelator of Fe/sup + +/, had little effect on the results.
