So I'm working with data from recent cotton harvest from a seed company. They're more interested in cotton seed than the fiber itself. I'm trying to come up with seed yield numbers for an array of cultivars but the data I was given came in kg of harvested fiber. Excluding any changes between cultivars due to genetics,

Does anyone have an idea of how many kg of cotton seed I can get from a given yield of cotton fiber?

Kind regards,

According to this document (pdf) the rate is around 700 lb seed per 500 lb of fibre.

seed = 1·4 × fibre

230 kg fibre ≅ 320 kg seed

(Strangely, the rate has fallen over time.)

  • $\begingroup$ Curious, it has indeed. 230 kg of fiber in our case yielded 226 kg of seed. $\endgroup$ Jun 16, 2017 at 16:05
