Abstract: A pot culture experiment was conducted with various fruit nursery plants of guava, aonla, ber, mango and kinnow as test crops. The six number of treatments viz., T1 (Control), T2 (FYM @ 250 g/10 kg soil), T3 (Compost @ 200 g/10 kg of soil), T4 (Recommended N, P, K), T5 (Vermicompost @ 160 g / 10 kg soil), and T6 (PSB + NS nitrogen fixer @ 3 g/10 kg soil) were taken into consideration each treatment having three replications. The treatment effect was monitored in the rhizosphere soils of fruit nurseries at 30, 60, 90 and 120 days interval in terms of total number of bacterial and fungal populations, sulphatase enzyme activity, mineral sulphur and organic sulphur. The maximum bacterial population of the order of 63 cfu x10 5 was recorded with the treatment (T6) i.e. non-symbiotic N2 fixers + PSB at 90 days of plant growth. The sulphatase enzyme activity was found to increase from 30 days to 90 days and soils treated with Vermicompost (T5) exhibited maximum sulphatase enzyme activity.The maximum mineral sulphur content was found with the Vermicompost treatment (T5) and the organic sulphur content was observed to be higher with the Vermicompost (T5 ) and increased from 30 days to 120 days in all the treatments.
