You say tomato, I see to-ma-to. Some people look at the same situation differently. Sometimes it doesn't make a difference, but sometimes it might. Picking whether to start with early-season soybeans or full-season varieties that you've selected once you get a chance to plant may be one of those situations. Not everyone looks at it the same way. Here's a different view backed by data.
"Based on current research data collected by Pioneer researchers from 2009 through 2011, full season varieties for your area if planted early if conditions are fit, could return higher yields," says Traci Bultemeier, accounts manager for Pioneer Hi-Bred, Ft. Wayne. She's an Indiana Certified Crops Adviser, and was reacting to a proposed strategy of planting early-season soybeans first, then later-season soybeans after that.
"Earlier (planting) dates allow these fuller season varieties to put on more nodes and more leaves," she says. Basically, they have more time for vegetative growth stages before flowering begins.
"More nodes can mean more pods and more leaves can mean more photosynthesis to support seed production. Of course there are risks involved. Early season pathogens, the risk of crusting and sudden death syndrome are a few that come to mind. However, planting when conditions are right for the field, use of fungicide/insecticide seed treatments and choosing varieties with high SDS scores can help to overcome these potential risks."
To evaluate such things as SDS scores, you'll need the help of your seed rep, experts say. The seed rep should also provide information on tolerance or resistance to the various phases of phytophthora root rot, and have information about resistance to soybean cyst nematode. Take all these decisions into account when deciding which varieties to plant when and where, and deciding which treatment sot use on various varieties.
