After heavy rain a patch of my soybean turned yellow and stunted in low lying ground. What is happening and what can I do?
Why are my soybean plants stunted and yellow soon after a heavy rain (soybean)?

Soybean is very sensitive to waterlogging, so yellow stunted plants in low lying patches after heavy rain are usually from waterlogging that starves the roots of oxygen and disrupts nitrogen fixation, sometimes followed by root rot. The immediate step is to drain the standing water quickly by opening field channels so the soil can breathe again. Once drained, the crop may partly recover, and a light foliar feed can help the surviving plants green up, but badly rotted plants will not bounce back. For the long term, make broad bed and furrow or ridge and furrow layouts and ensure good field drainage so water does not stand on soybean. Avoid sowing soybean in the lowest waterlogging prone spots. Get the drainage layout and any recovery spray advice from your local KVK.

Broad bed and furrow planting changed everything for me in Washim. Earlier my soybean drowned in the low spots after every big rain. Now the water drains off and the crop stays green.

The first thing I do after a heavy rain is open the field channels and drain the standing water fast, the same day if I can. The longer the water sits, the more plants turn yellow and rot. Quick draining saved the patches that were only briefly flooded.

I learned to just not sow soybean in the lowest waterlogging prone corner of the field, because it drowns there every wet year no matter what. I put a hardier crop in that spot now. For the rest, a light foliar feed after draining helped the surviving plants pick up, but the rotted ones never came back.

Sowing on a slight ridge or raised bed from the start kept my roots above the worst of the standing water, so the same heavy rain did far less damage than on my old flat sown plot. Pair that with channels that actually carry the water off the field and the crop comes through wet spells much better. Plan the layout before sowing, it is hard to fix once the rain comes.

A light foliar feed after I drained the water helped the plants that were only stressed, not rotted, to green up and pick up again. The badly rotted ones never came back, so I did not waste spray on them. Drain first, then support the survivors, and get the recovery spray advice from your KVK.

Keeping the main drainage channel of the field clear before the monsoon meant the water actually had somewhere to go when the heavy rain came. The year my outlet was choked the water just sat and the soybean drowned. Clean the channels and outlets before the rains, not after the field is flooded.
