Abstract– In the present study, diversity and abundance of protozoa in two paddy field was examined. One of the paddy field was moist and other flooded. It was observed that the abundance of protozoa was lower in flooded field. Abundance of protozoa in surface soil of flooded field was recorded as 27 ind./g soil while abundance in moist paddy field was recorded as 44 ind./g soil. Abundance of protozoa was also recorded in deep soil up to depth of 10cm where abundance of protozoa in flooded paddy field recorded as 23 ind./g soil and in moist paddy field at 10cm depth abundance of protozoa was recorded as 25 ind./g soil. Altogether 11 genera of protozoa were recorded from both paddy fields. Physicochemical parameters of soil were also studied. pH value of soil in moist paddy field was observed as 7.2 while in flooded field pH was slightly acidic (5.8). Nitrogen content of flooded field was also low (52.34%) in comparison to moist field where N2 content was recorded as 55.58%.
