Increasing the Elongation of the Cotton Fibers
The main elongation occurs within the first 3 weeks after Anthesis. Fibers are single cells and can increase in length more than 1000 times. Potassium is very important for cotton production, it affects fiber properties such as micronaire (measure of fiber fineness and maturity), length and strength.
It also supports functions in enzyme systems and water use efficiency. During the elongation phase potassium maintains the internal water pressure in the boll, thus promoting the process. The need for K increases dramatically during the early boll set, and approximately 70% of uptake occurs after first bloom.

Cotton Crop Nutrition – Finding the Right Program
Creating the right nutrient management strategy in Cotton production is not a “one-size-fits-all” prescription. Cotton is grown in vastly different environments with differing soil conditions and yield potentials. Any nutrient program needs to be designed for these variables. But where do you start? Find these answers and more in this free webinar by Cotton Grower.
