Interaction Among Atrazine, Temperature, and Phosphorus-Induced Zinc Deficiency in Corn (Zea mays L.)
1970
Rudgers, L. A. | Demeterio, J. L. | Paulsen, G. M. | Ellis, R.
Corn (Zea mays L.) was grown with two levels each of P and Zn with and without atrazine in the field on recently leveled P- and Zn-deficient soil and in nutrient solutions in environmental chambers. Severe Zn deficiency symptoms were exhibited by field-grown corn receiving no Zn and were accentuated by P fertilization. Atrazine had no evident effect on deficiency development. Phosphorus and Zn concentrations in leaves, but not in grain, of field-grown corn were increased by atrazine. In environmental chambers, corn seedling growth was decreased more by atrazine toxicity than by P or Zn nutrition. Phosphorus and Zn concentrations were increased frequently by atrazine at low but not at high growing temperatures. Atrazine had little apparent effect on P-induced Zn deficiency development in the field or in environmental chambers.
