Strictly speaking, a production question but how long for soybean pod fill in Sept-Oct?

This is strictly speaking a production question but I'll post it here anyways. 

  I've finally got full sized pods on my later planted beans, pods with embryos but no sign of pod fill. I've never had beans this far behind before, usually the pods start to fill in mid-August at the latest and even then they don't start losing their  color until Oct.

  These are 2.0 maturity group beans,  does anyone have an opinion about how long it will take to fill these pods?

Re: Strictly speaking, a production question but how long for soybean pod fill in Sept-Oct?

Based on charts from National Crop Insurance Services --  

R4 -- Pod 3/4 inch long at one of four uppermost nodes, 9 days to R5

R5 -- Seeds 1/8 inch at one of four uppermost nodes, 15 days to R6

R6 -- Green seeds fill pod cavity at one of four uppermost nodes, 18 days to R7

R7 -- One normal pod on main stem is mature pod color, 9 days to R8

R8 -- 95% of pods brown

Consider the # of days to be based on "average" weather.

"Pods brown" does not necessarily mean the beans are dry.

 

Starting to see a lot of SDS in my area, just came on strong in past week.

Re: Well, based on those criteria, ......

Well, based on those criteria, my beans are in R5 and need another 42 days to maturity.  So, it's still possible to make a crop but the days are already getting noticeably shorter and temperatures cooler.
