Abstract
Results of the field experiment conducted at Kasaragod revealed that FYM and vermicompost application alone decreased the bulk density, improved soil porosity, organic carbon, pH and maximum water holding capacity (MWHC) to a greater extent, whereas composted coir pith had its effect on these characters to lesser extent, except MWHC. The microbial population and dehydrogenase activity were also higher under FYM and VC treatments compared to CCP treatments, whereas under NPK alone and control there was no change In physico-chemical properties but the microbial count and their activity declined. Among organic manures, FYM + NPK combination recorded significantly higher yield components and fresh rhizome yield (6.2 t/ha) compared to FYM, VC, CCP and NPK applied alone. Fresh rhizome yield under mother rhizome was significantly higher compared to finger rhizome.
