Boll Factors

Boll Factors are estimated bolls per metre per bale per hectare.

Boll factors will be best utilised for comparison between varieties although environmental and management factors can also effect relative boll sizes eg. Verticillium wilt infestations may affect relative boll size in susceptible varieties.

You can find out more information on boll factors by visiting this previous Facts on Friday.
