Abstract: The live green biomass of a grassland community in Podadiha Forest Block (86o 27’ E; 21o 33’ N) of Similipal Biosphere Reserve was studied from July 2015 to July 2016. Short term harvest method of Odum (1960) was employed for the determination of various compartmental biomass values. The live green biomass of the community showed gradual increase in biomass value from July to August, then to September, October and November, and attained a peak during December (255.88 g m-2). Thereafter, the value started a decreasing trend till May (72.92 g m-2). Again an increasing trend of value was observed till the end of the sampling period. The mean live green biomass of the community was found to be 125.34 g m-2. Compared to other grassland communities the mean value of the community did not show any similarity with the value of others. The variation of live green biomass of a grassland community from place to place and from time to time might be due to the variability in climatic condition, topography, soil characteristics, microbial activities in the soil as well as the biotic interference of the locality.
