Response to Zinc in Maize Crops in the Argentinian Pampas

IPNI-2009-ARG-29

Response to zinc of maize crops in the argentinean Pampas The objectives of this project are: To quantify Maize response to Zn in the Pampas region. To determine the optimum Zn rate for corn. To validate locally Zn analysis and critical levels. Field experiments are carried out for 2-3 years at different locations of the Pampas regions (Río IV: Chaján, Río IV, Carnerillo; Marcos Juárez; Oliveros; Rafaela; Pergamino; 9 de Julio; Daireaux/Pehuajó; Balcarce/Tandil; Necochea/Lobería).

Interpretive Summary

Grain crops grown in the Pampas region of Argentina, especially maize, often show Zn deficiencies. However, research on maize response to Zn fertilization is scarce. The objectives of this research project were to: 1) quantify maize responses to Zn fertilization in the Pampas region; 2) determine the optimum Zn application rate for maize; and 3) validate local Zn analyses and critical levels.
