Effects of Potassium Chloride and Sulfate on Pineapple Yields and Quality

Abstract

An experiment was conducted on a Bayamón sandy clay to determine whether the chloride or the sulfate was the best source of potassium for pineapples. The results were as follows: 1. Pineapples fertilized with potassium sulfate gave a higher yield per acre and a larger mean weight per fruit than those which received potassium chloride. 2. The chloride-fertilized pineapples produced a fruit with off-colored pulp not as acceptable as the standard sulfate-fertilized fruit. 3. The possible roles of the chloride and sulfate ions in pineapple yields are discussed.
