Cotton Still Dealing with Heat and Low Yield Potential
Mon, 19 Sep 2011 09:38:23 CDT
The extreme heat wave across Oklahoma for a majority of 2011 finally broke on September 4, however there are some areas of the state still in the 100 degree category. Altus is on the verge of having 100 days of 100 degrees, while Grandfield already broke that record earlier this year. And the cotton crops in southwestern Okahoma are still suffering from these high temperatures.
Many of the fields that have been surveyed over the past two weeks show that irrigated cotton will yield less than desired. Some cotton producers are still running pivots in late planted or replanted fields in attempts to make harvestable bolls from blooms that were set after September 1, which can be risky in southwestern Oklahoma. Also, many irrigated fields have some open cotton at this time.
When it comes to crop insurance, producers need to be meeting with crop insurance adjusters to obtain yield determination as soon as possible. The accepted date for moving from the stand count adjustment method to the boll count method has already passed on September 15. A large number of irrigated fields may also be lost to low yield potential.
After crop insurance has released a field because of low yield potential, producers should consider terminating their cotton crop with a high dose rate of paraquat or shredding to allow for crop residue to remain on the field. This will provide a potential to reduce wind erosion.
