The grazed grasslands of the India are an important resource as it contributes environmentally, economically but also in social development of the country. In the current growing industrialization the effective use land and continuous degradation in the grassland productivity has become one of the prime concerns for the country. In this study the primary productivity of a Grazed grassland commune located at Kota of Bilaspur district, Chhattisgarh lies between 〖21〗^047’ to 〖23〗^08’ North latitude and 〖81〗^014’ to 〖83〗^015’ East longitude have been considered. A quadrate of 0.25 gm-2 is used for sampling the above ground plant parts and size of quadrate is determined by Species Area Curve Method. The grassland community comprised of 13 species (7 were grasses and 6 were non-grasses). Bothriochloa Pertusa, Cynodon dactylon, dactyloctenium aegyptium, and eragrastris mutan among the grasses and Alternanthera sessilis, Alycicarpus Monilifer, Desmodium Trifloriun, and Sida cordifolia among the non-grasses were found dominant during the study period. Results show that, the annual grass production was found to be 1305.95 gm-2/year. The non-grass production showed maximum in the month of October (53.49 gm-2) and minimum in the month of June (2.80 gm-2). The annual non-grass production was found to be 430.84 gm-2 /year. This study informed about the natural ecosystem and the primary productivity helps to the earlier balanced state. Our study provides a interesting future direction that how, human and climate changes affect the net productivity and biodiversity of grazed grassland community.
