Population, Morphological and Biochemical Characterization of Microorganism in Plantain Root across different Farmlands in Toru-Orua Metropolis, Bayelsa State, Nigeria

Abstract

This paper assessed the population, morphological and biochemical characterization of microorganism in plantain root across different farmlands in Toru-Orua Metropolis, Bayelsa State, Nigeria using standard methods. Data obtained show that microbial population count ranged from 1 × 10⁷ - 9 × 10⁷ (cfu/g) in the study area, while fungi isolated include Aspergillus fumigatus, Aspergillus niger and Aspergillus flavus. These are the largest of all microorganisms in the soil. Others were Rhizobium, Nitrobacter, Winogradkyl, Azomona argillis and Psydormonads aeruginosa. Practices that would enhance nutrition of the plants and the proliferation of bacteria and fungi around the roots of plantain are recommended such as organic matter accumulation in form of green manuring, zero tillage and non-use of chemicals and burning.
