Damages of soybean because of waterlogging are chlorosis,
necrosis, stunting, defoliation, reduced nitrogen fixation,
and plant death which causes yield loss [14–18] and all of
these symptoms occur at various vegetative and reproductive
stages of the plant [16, 18–21]. Only 2 days of flooding can
cause 18% of yield loss at late vegetative stage while it may
exceed to 26% if flooding occurs at early reproductive stage
of soybean [19]. Flooding regularly affect soybean growth and
grain yield around the world including USA
