The Question of the Week.
10-31
When is this top crop going to open? This is a great question. The first point I am going to make is that it definately is going to open, when it has had enough heat, sun, and low humidity. The top bolls that have not opened are primarily bolls that bloomed at the end of August and while mature, they where around 6 or 7 NACB when the field was defoliated. For cotton to open two weeks after defoliation, it generally has to be within 4 NACB. For bolls that are 6-7 NACB, it takes 3 weeks after defoliating and if you had bolls 8 NACB, it can take 4 weeks to open. That is with normal October and favorable conditions. If we have long stretches of cloudy cool weather, it can be longer.
How much yield can I expect for waiting? The best answer for this is to count bolls per 10 foot that are not opened and fluffed with seed that crack. If you have 50 bolls per 10 feet, normally that would be about 250 pounds per acre. Since these are top bolls and likely not fully mature, 50 bolls/10 ft probably represent more like 150-250 pounds per acre.
My advice is to wait if it's that many bolls at the top. Once you get down to 10-15 bolls per 10 feet, that could still be 30-40 pounds.
If your cotton was sprayed after October 15th and was not within 4 NACB, then it likely needs more time and that is perfectly normal.
