Abstract

Yellowing of arecanut (Areca catechu L.) being one of the major constraints in their cultivation has been associated with water-logged condition and nutrient imbalances. The current study was conducted to understand the essential difference in the nutrient concentration and rhizosphere bacterial population in yellowing affected and healthy arecanut palms. The high concentration of iron and copper in the rhizosphere of the yellowing affected palms reflected the nutrient imbalance prevailing in the effected ecosystem. The rhizosphere of healthy palms with no yellowing symptoms had increased population and species richness of bacteria. It was found to be correlated with ideal physical–chemical conditions prevalent in the healthy rhizosphere compared to the yellowing affected palms in the same plantation. An increased population of the bacterial phyla Proteobacteria, Acidobacteria, Gemmatimonadetes, Verrucomicrobia, Bacteroidetes, Firmicutes and the genera Mucilaginibacter, Sphingomonas, Bacillus, Bradyrhizobium, Burkholderia in the healthy rhizosphere reflected the health of the arecanut palms when compared to the yellowing affected palm rhizosphere with less biological activities.
