ABSTRACT
A pot culture experiment was conducted with four mulberry varieties viz., V1, S36, S13 & M5 treating with sewage and bore well water to study the influence of sewage water on diversity and population of microflora of rhizosphere soil. The rhizosphere soil collected from each variety was studied for the bacterial and fungal population and roots were studied for the percentage root colonization with AM fungi. The results indicated a significant reduction in fungi population and percentage root colonization with AM fungi in the mulberry varieties treated with sewage water, besides a change in fungal diversity. However the bacterial population was significantly higher on sewage water treatment, though similar groups of bacterial colonies were found in both the treatment.
Key words :
AM root colonization, Bore well water, Fungal, Microbial diversity & Population, Mulberry varieties, Rhizosphere soil, Sewage water irrigation.
