Verbatim
e0“Corn ( Zea mays L.) and pinto beans ( Phaseolus vulgaris ) were used as test crops to study the interactions between P, Fe, and Zn in a calcareous solution culture”
e1“A P/Zn concentration ratio > 300 resulted in a slight depression in yield in the presence of an adequate supply of Fe”

Other claims from this paper (8)
- Intervention effect Adding Zn to the intermediate Fe level accentuated Fe deficiency and depressed corn yield.
- Association Yield of corn was reduced when the tissue Fe/Zn ratio fell below 1.5.
- Association The adverse effect on corn yield was not related to Fe concentration in the plant but was associated with a decreased Fe/Zn ratio.
- Intervention effect Adding Fe corrected the adverse effect of Zn on corn yield.
- Intervention effect Increasing P at the intermediate Fe level first increased corn yield.
- Association Further P increase caused P-induced Fe deficiency and a depression in corn yield at a P/Fe ratio above 60.
- Association Adding Fe did not change the Fe concentration in the plant.
- Association The yield depression caused by Zn-Fe and P-Fe-Zn antagonism was not found with pinto bean at the concentrations studied.
