| The objectives for this research project were to determine water use curves for three peanut cultivars under two different irrigation regimes; to determine the relationship between aflatoxin contamination and water use in these peanut cultivars; based on differences in the water use curves between irrigation treatments, provide recommendations for optimal growing conditions among the tree cultivars.
Plots were established under rainout shelters located at the National Peanut Research Laboratory in Dawson, GA during the 2002 growing season. Date collection was completed that quantified water use for three different peanut cultivars, Georgia Green NCV-11, and Andru II under both overhead and subsurface drip irrigation. The relationship between water use during imposed drought, TSWV infection progress, and final aflatoxin production at five different harvest dates were analyzed.
A variation in cultivar drought response and TSWV progression was found. The experiments were to be continued during the 2003 growing season to validate these responses.
