Canola and heat

[vvalk]

In a thread before SF3 mentions flower blast at 28. I was thinking that I don't find that. Flowers actually love heat. It's the drying too fast that doesn't allow the flower to fertilize and produce a pod. I find that in the 29-33 ish range,if it's calm and humid, the flowers still put pods out. It's the low humidity and wind that cause the real problems. What do others think?

we have noticed the same , high humidity will save a person during a heat blast . it's the hot dry wind that cooks it

I agree
Over 32 gets unhappy or low humidity below 35 percent. Now we have Canola turning blue white by noon.... In heat of the day... No doubt these crops are stressed. Cool nights help with rehydration and canola to follow the moisture down if reserves remain.

What humidity and what crop?

Does it matter if a 10 bushel crop gets flower blasted? The farmer is so under water on the inputs of the crop by that point it really isn't worth looking at.

I see smart phones must not be... I pressed submit only once.

28.4 is the magic number if moisture is not deficient. This is well studied. Pollen is sterilized at that temperature not matter what. Low humidity and moisture stress lower it considerably yet.

20% humidity, 30 plus with 6/10ths of rain since April = FUBARed!

Not suggesting it's God for the crop just saying when is calm 32 and some humidity the crop is still pushing some pods out.

Ado. So your saying at 29 and over all pollen is sterilized and no pods are formed what's so ever?
