Abstract: A field experiment was conducted during winter (rabi) seasons of 200 1-02 and 2002-03 at \"C\" Block Farm, B. C.K. V., Nadia, West Bengal to study the effect of herbicides on soil micro flora and soil micro nutrients. Highest yield of rice was obtained from the treatment PSF 10 WP@ 100 g/ha. Pyrazosulfuron-ethyl proved stimulatory for both the beneficial organisms such as phosphate solubilizing bacteria and non-symbiotic N-fixing bacteria where as acetochlor showed negative response. Though availability of micronutrients did not follow any definite pattern of change with crop growth but higher availability was found in case of PSE 10 WP over acetochlor.
