ABSTRACT

Soursop grows in a wide range of soil. The soil environment is the most complex habitat on earth and provides a range of habitats that support an enormous population of soil organisms. Water exerts strong influences on soil processes including microbial growth and changes in precipitation patterns associated with climate change, giving rise to the question of how changes in soil-water availability will affect microbial growth efficiencies. This project was designed to determine the microbial diversity in soil planted with soursop under varying watering regimes. The experiment was carried out in the department of Crop Science Laboratory, Faculty of Agriculture, University of Benin, Edo State to isolate, and identify the various microorganisms present in the soil and determine the microbial frequency of the soil. The experiment evaluated the effect of watering regime, soil media and soil incubation duration. Microorganisms were cultured, isolated and identified. The experiment was laid out in a Completely Randomized Design (CRD) with two replications and were separated using StudentNewman-Keul test.
