Many farmers often like to estimate soybean yield late in the season. Ideally, the closer the beans are to maturity, the better the estimate will be.
The traditional approach to estimating yield by the formula (pods/acre X seeds)/pod /(seeds/lb.)/(lbs. per bushel) is time consuming and tedious. There is a simpler approach that is based on counts in 1/10000th of an acre, by measuring 21 inches of row for any row width.
