Evaluation of Potassium Fertility in a Common Agricultural Soil of Arizona
Abstract
Two field experiments were conducted during the 2001 growing season to address potassium (K) fertility response of two commonly grown varieties of cotton in Arizona. The studies were conducted near Coolidge, AZ in two separate fields and each consisted of two treatments, an untreated control and a treatment receiving a preseason side-dress application of K fertilizer. Plant growth and development estimates revealed that fruit retention (FR) and height to node ratio (HNR) levels were similar for both treatments in both fields. Lint yield data also indicated no difference between the fertilized and unfertilized treatments in both fields.Series/Report no.
