The effects of salinity on corn plants (Zea mays L.) are influenced by
the concentration of nutrient orthophosphate. Salinity (-2 bars each of
NaCI and CaCI2) was more injurious in combination with a high concen-
tration of orthophosphate (2 mM) (that gave optimum yields in the
absence of salinity) than it was with a lower concentration (0.1 mM).
