NE Indiana | Many things can be different if just comparing to the neighbors. We start with beans as soon as the ground is fit in April. Early beans outyield our later planted beans almost every year. Also, beans are tough. They can handle a cold and wet conditions during emergence and come through just fine. We don't have that same experience with corn and typically a cold and wet spell during emergence results in replant or significantly uneven stands. We have started waiting on corn until later in April unless the future forecast is warm and dry out 2 weeks or more. Having said all that early planted corn into ideal conditions with ideal forecast can have a significant yield advantage over later planted corn in the same conditions. So as always weather trumps everything.
Also, something to think about, early beans will benefit greatly with some added sulfate sulfur. The later they are planted the less response you will see.
We have had really good luck using our earlier varieties for our earliest planted fields. 2.2-2.6 range. We will plant up to a 3.5 but usually try to save those for last as they don't usually yield as well if planted early.
We have 2 planters so that makes our plan pretty flexible. If we only had 1 planter I would always plant beans first unless weather delays kept us out of the fields until May. Then I would get corn done first because it seems beans planted beginning of May through end of May have very little yield difference but early may corn will usually significantly outyield late May corn.
