Chippewa is a new soybean for extreme northern Iowa. It's high yielding and high in oil content. Chippewa is 5 days earlier than Blackhawk. So it should be of special interest to you if you live in an area where you want an earlier variety than Blackhawk. Chippewa is considered a replacement for Mandarin (Ottawa), Captial and older varieties of similar maturity.
