Abstract
A field experiment was conducted to study the effect of organic manures on certain physico-chemical and biological properties of soil and crop yield of arrowroot when grown as intercrop in coconut garden. Organic manures like. FYM and vermicompost (VC) application alone and FYM+NPK application decreased the bulk density, improved soil porosity and maximum water holding capacity (MWHC) to a greater extent, whereas composted coir pith (CCP) had its effect on these characters in lesser extent except MWHC. Organic carbon and pH of the soil was increased to a greater extent under FYM and VC treated plots compared to CCP. There was no change in above physico-chemical properties under NPK alone and control treatments. The microbial population and dehydrogenase activity was also higher under FYM and VC treatments compared to CCP treatments, whereas under NPK alone and control there was decrease in the microbial count and their activity. Among organic manures. FYM+NPK combination recorded significantly higher yield componments and fresh rhizome yield (17.1 t/ha) compared to FYM. VC. CCP and NPK applied alone.
