Drought stress effects on corn and soybean differ in terms of the calendar
timing of the stress and its relative effect on the two crops. July dryness
is often considered to be most severe for corn pollination and early grain fill
of the developing kernels. August dryness is often considered to be most severe
for soybean flowering and pod set. Unfortunately, some areas of Indiana were
afflicted with severe dry conditions during all of July and August in 2002,
resulting in greater than usual rates of seed abortion (corn and soybean), flower
abortion (soybean), or poor pollination (corn).
