Boll factors provide an indication of how many bolls/m are required to produce 1.0 bale/ha; and are also a good indication of the comparative boll weights between varieties.

If everything else is equal, a variety with a lower boll factor will achieve a higher yield than a variety with a larger boll factor with the same boll counts. Additionally, there are regional, seasonal and stress related impacts which can alter the relative boll factors.

Dryland results shown are per linear metre, a row configuration multiplication factor is needed to estimate yield potential.
