Abstract

Given that coco pith is a versatile growing medium, understanding the factors that influence its physicochemical properties is crucial for optimizing its use. This study examines how soil suitability class, coconut variety, milling method, and ageing status affect electrical conductivity, pH, and the concentrations of Na+ and K+ in coco pith. Husks from Tall×Tall (TT) and Dwarf×Tall (DT) varieties were processed using dry and wet milling methods, with and without ageing, across 43 blocks representing different soil suitability classes. Results showed that milling method significantly (P
