Planting soybeans earlier in the season continues to show clear yield benefits, according to Indiana crop advisers, but investing in a second planter is not a straightforward decision. Research and field experience consistently indicate that soybeans planted in late April often outperform later plantings, forming more nodes and capturing sunlight earlier, which translates into higher yields.
Danny Greene, a certified crop adviser from Franklin, explained that extensive planting-date trials, including work by University of Wisconsin specialist Shawn Conley, show that soybeans have the highest returns when planted through April 20. Corn may take the lead in early May, but as planting is delayed further, soybeans regain the advantage. “Early planting allows soybeans to form more nodes before flowering and capture more sunlight during the season,” Greene said.
However, whether to purchase a second planter depends on farm logistics, labor, and cash flow. Greene noted that while the biological advantage is clear, the economic answer depends on whether the yield gain from early planting offsets the cost of the additional equipment.
Bryan Overstreet, soil conservation coordinator in Rensselaer, emphasized that early soybeans are more beneficial than early corn if resources are limited. “Yield suffers more for corn than for soybeans when emergence is uneven,” he said, cautioning that adding a second planter also requires more tractors, workers, and equipment to manage dual operations.
Dan Ritter, an agronomist with Dairyland Seed, echoed the benefits of early soybean planting, noting research from Wabash, Indiana, where late-April plantings consistently produced the highest yields. “From late April to late May, there was roughly a 5-bushel-per-acre yield difference,” Ritter explained. He added that frost risk increases for very early April plantings, so timing must balance potential yield and risk.
Economically, Ritter recommended running the numbers: assuming a 3.5–5 bushel per acre advantage at $10 per bushel, early planting can provide $35–$50 per acre in additional revenue. Custom planting rates are typically $21–$22 per acre, meaning that even outsourcing early planting can be profitable.
In conclusion, while early soybean planting offers a measurable yield advantage, the decision to invest in a second planter hinges on operational capacity, labor availability, and cost analysis. Farms able to manage logistics efficiently can benefit from the early start, but careful planning is essential to ensure the investment pays off.
