Abstract:

Soil microorganisms are supportive in the transformation of soil phosphorus (P) and are thus an important component of the soil P cycle. These are effective in releasing P both from inorganic and organic pools of total soil P through their respective solubilizing and also enhance the soil microbial and enzymatic activities. To evaluate this an agronomic trial was conducted with a local high yielding variety of rice (cv. Shahsarang) during 2012-13 kharif season to find out the influence of phosphorus levels and PSB strains on soil microbial and enzymatic activities at Barapani, Meghalaya in North Eastern India. The soil microbial carbon (C), nitrogen (N), phosphorus (P) (454.05, 70.35, 17.22 µg g-1) and dehydrogenase activity (DHA) were found significantly higher (5.61 μg TPF g-1 h-1) at 60 kg P2O5 ha-1 dose than other levels of P and with inoculation of Pseudomonas sp. (481.19, 68.18, 16.11 µg g-1 and 5.03 μg TPF g-1 h-1), respectively. Interaction effect was found significant on soil microbial C, N, P activities and DHA at 60 kg P2O5 ha-1 when associated with Pseudomonas sp. Higher value of phosphatase activity (PHA) was found (37.15 μg pNP g-1 h-1) with P control and with inoculation of Pseudomonas sp. (35.14 μg pNP g-1 h-1). The interaction of P control and Pseudomonas sp. was found significant for PHA. The main objective of this study was to assess the effect of P levels and PSB strains on soil microbial and enzymatic activities.
