Double-cropping cotton behind wheat

(The following letter was written in response to “Double-cropping cotton profitable?” in the Oct. 26, 2007, issue of Delta Farm Press. The article can also be found at www.

I enjoyed very much your article on this subject. I am starting to harvest my fourth double-crop wheat and cotton.

My experience has been exciting, but this will only work if you have good moisture for cotton planting. I do mine under a pivot with great success.

I have 170 acres this year (that) averaged 69 bushels per acre of wheat and now (has) a great crop of cotton.

I fertilized the cotton as if it had no wheat and have zeroed in on a great cotton seed that works in this system. My seed of choice has become Stoneville 5242 and it's successor.

In the previous three years, I've picked an average of 950 lint pounds and this cotton crop looks better than any previous one.

I am 100 percent strip-till cotton with conventional tillage on the wheat. I sell an average of three rolls of wheat straw per acre, so you can see this is pretty intense management.

One drawback I've had is the cotton stalks seem to be weaker in this system and tend to lay down somewhat with a tremendous green boll load in the plant tops.

However, now that the cotton is fully opened, the vine lifters on my IH2055 4-row picker seem to be doing a great job as the open bolls are not as close to the ground as be green ones were.

Not many Georgia Extension personnel are embracing this type system. I'm glad to see a neighboring state do it.

By the way, my farm is in Laurens County, Ga., and is in good cotton and peanut ground.

Severe stress and green soybeans

(This letter is in response to “In Arkansas Green soybeans prolonging harvest” at

Just thought I would share what I think is the main cause of green stem, pod, and leaf soybeans.

I farm and run a seed plant in east-central Kansas and we see a lot of it. I feel that it is caused by severe stress at a critical time.

Sometimes it is green leaves and pods on only one or two nodes. Those nodes will have very few, if any, pods on them. If (they do) have a pod, it will usually (contain) only one bean.

This year, (I'm seeing such a situation) big-time in irrigated soybean circles. Where there was adequate water inside the circle, the beans are very good and have matured.

In the worst areas outside the circle, in the corners where the end gun did not reach, the beans have numerous green stems and leaves with very few pods.

Soybeans are like all plants and creatures programmed by God to reproduce their own kind.

When a severe stress comes along and stops normal development, they stay green to try to reproduce.

Of course, with soybeans being a photoperiod-sensitive plant, they are waiting for ideal conditions to return so they can reproduce on whatever nodes, or part of plant that did not reproduce. It will not happen because the photoperiod is to the point that they will not re-bloom.

In other years, I have seen (green plants) caused by corn earworm damage. In areas where the worms did the most damage and there are few or no pods left, the beans will remain green until frost kills them.

We are seeing the same thing this year and we think it is from intense heat and drought at a very critical stage.
