Bruchid damage doesn't stop them growing.I am allowing for a lot of losses. It’s uncleaned fss. I counted out 100 seeds and found 25 either damaged/v small or bruccid damaged and there is a 7% admix of broken seeds etc. taken into account in the tgw.
But yes if it's uncleaned fss then a higher rate is easily justified, you'll have the split ones for a start, and there's plenty of them in my heap this year ftom them being so dry.
