Crop May Have A Place In Areas Where Water Is Less Available

Is there room for cotton in Kansas … the Wheat State?
There certainly is, says Kansas State University water resources engineer Jonathan Aguilar, who is currently studying the best ways to grow a crop that is traditionally grown in warmer climates.
“One of the reasons we are looking at cotton is because it is drought resistant, or at least doesn’t need a lot of water compared to other crops grown in (southwest Kansas),” says Aguilar, who is located in K-State’s Southwest Research and Extension Center in Garden City.
“The other reason we are doing research on growing cotton is because we are at the northern edge of cotton production in this region. We’ve been growing cotton for three years; our first question was whether it will grow here, and if it will, can it produce a decent yield?”
So far, he says, the answers are “yes” and “yes.”
“We are still getting samples for this year’s crop,” Aguilar says, “but it looks like we will have a nice yield.”
Much of K-State’s research is focused on irrigated cotton as part of a rotation with other crops. Even though researchers are using available water, Aguilar says the crop requires less of it than other crops.
“Surprisingly in our region — and I think our colleagues in Oklahoma say the same thing — if we put more water on cotton, it actually diminishes the yield compared to when you are putting just the right amount, or even limiting the amount of water the crop receives,” he says.
In other words, growing cotton in Kansas may require applying water at the proper time, rather than the actual volume applied.
“We are finding that if we put water just at the critical stage of growth, it will outperform fully irrigated cotton.”
Aguilar notes that K-State’s research will continue for two more years to fully understand the proper management to grow profitable cotton in the state. Compared to states such as Texas and Oklahoma, Kansas has fewer warm days. In addition, plant populations are not the same as they are for cotton grown farther south.
“There’s an art and a science to cotton,” Aguilar says. “We are learning more about that. There are instances when we can apply water at the right time when it will produce more compared to not applying water in a strategic way.”
