Effect of primary productivity on Indian grassland (Bilaspur District, Chhattisgarh)

ABSTRACT Productivity of grassland has become the main concern not only for the researchers but also for the environmental perspective. The Prime objective of this study elicited the environmental stability and its importance on their climate changes with respect to geographical variation. Fields for this study is selected from the central India, located at Chhattisgarh, Bilaspur, District, Dheka which lies between 21 47’ to 23 _8’ North latitude and 81 _14’ to 83 _15’ East longitude. To collect the sample for the above ground part a circular quadrate of 0.35 has been used. Species Area Curve Method is applied to determine the size of quadrate. The grassland community comprised of 14 species (7 were grasses and 7 were non-grasses). Bothriochloa Pertusa, Cynodon dactylon, Digitaria longiflora, among the grasses and Desmodium Triflorum, Parthenium and Sida cordifolia among the non-grasses were found dominant during the study period. Results shows that annual grass production 3187.52 /year. Similarly, the non-grass production showed (120.20 ) for December and (1.72 ) in May as maximum and minimum respectively. The annual non-grass production was found to be 734.46 /year. The study of primary productivity helps to recovery of the natural ecosystems to the earlier balanced state and continuation the biodiversity of grassland community in world.
