In a southwest Kansas study, researchers tested different water-saving methods for growing cotton under an irrigation system. They tried using less water at different levels to see how it affected the cotton plants. Surprisingly, reducing water didn't significantly decrease the amount of cotton produced. In fact, cotton grown without any irrigation almost matched the yield of fully irrigated cotton. The plants seemed to do better without some water compared to getting just a bit less water. These results suggest that cotton production in western Kansas can potentially thrive even with no added irrigation. The findings hint at the possibility of saving water while still growing successful cotton crops in this region.
