Sometimes high TW is associated with high grain yield and low TW is associated with low grain yield. In fact, there is a poor relationship between TW and yield. The same TW can exist across a wide range of yield environments and genetics. Similarly, there can be a wide range of TW values across the same high or low yielding environment. That said, high TW corn can result in a grower being paid for more "bushels." For example, there are more bushels (those 56 lb. blocks) of 58 lb. TW corn in a truck or bin than the same truck or bin with 54 lb. TW corn.
