Abstract

The present study was carried out on the isolation, quantitative and qualitative analysis of microflora from the rhizosphere soils of Cassia angustifolia. The plants were grown in pot culture experiments with three treatments in black soil, treatment No. 1 is a control soil without any addition, treatment No. II is soil introduced with Cadmium 10ppm, chromium 20ppm, nickel 16ppm, treatment No. III is soil with 1% of calcium hydroxide along with heavy metals and were grown up to productivity levels. The fungal population in (treatment II) heavy metal treated soil showed minimum number of cfu/gm soil as compared to other two treatment types. Fungal species composition is almost same in control soils whereas heavy metal + Ca(OH)2 treated soil has increased number of fungal species. The (treatment II) heavy metal treated soil showed bacterial population in 103dilution and heavy metal + Ca(OH)2 treated (treatment III) and normal soil showed high bacterial population when compared to heavy metal treated soil type
