Influence of Organic Amendments and Soil pH on Management of Rhizome Rot of Ginger

摘要

Rhizome rot of ginger is the most serious disease of ginger which causes both quantitative as well as qualitative yield loss. The disease is soil borne in nature and soil pH as well as soil organic matter plays an important role on management of rhizome rot of ginger. The present study was conducted to find the effect of soil pH and soil amendment in the form of adding vermicompost on rhizome rot of ginger. An experiment was conducted with five levels of soil pH and three levels of vermicompost. Fromthe study it was found that organic amendment and soil pH influence on disease incidence. It also revealed that the treatments with vermicompost as soil amendment @ 6 t ha 1 and soil pH at 5.5 was found to be the most promising with highest average yield and lowest disease incidence of 28.33 per cent.
