Interactive effects of water table depth, rainfall variation and sowing date on maize production in the Western Pampas

This research paper evaluates the interaction between water-table depth, rainfall variation, and sowing dates on maize yields in the Western Pampas of Argentina, identifying an optimal water-table depth for maximizing production and stability.

• Maize yields across four evaluated conditions (early sown-dry, early-wet, late-dry, and late-wet growing seasons) exhibit an optimum water-table depth range of 1.5–2.5 m, where average yields are highest and most stable at approximately 11.6 Mg ha&minus1.
• Water-tables shallower than 1.5 m lead to yield declines across all conditions due to waterlogging, while water-tables deeper than 4 m significantly reduce yields to between 25% and 50% of those seen in the optimum range.
• Maize in areas with deep water-tables is highly dependent on rainfall during the flowering period for yield, whereas maize in areas with optimum water-table depth shows high temporal stability and independence from rainfall during that same period.
