The leaf concentrations of N, P, and K were primarily influenced by the respective fertilizer nutrient, except P, vhich also was influenced by the fertilizer N. Increasing rates of the nutrients well above those recommended for normal corn production increased the leaf nutrient concentrations, but not yields after the first increment of fertilizer. The effect of dry veather reduced yields 0.7 quintals per hectare per day and also vas negatively correlated with the leaf N and leaf P concentrations (0.01 probability level).
