PHYTOSOCIOLOGY AND PRIMARY PRODUCTIVITY OF THE MACROPHYTES IN DAMOAR RIVER, JHARKHAND, INDIA

PRAGATI PRAKASH, V K PRABHAT

Abstract

The present paper deals with phytosociology and productivity of the macrophytes in damoar river, jharkhand, india Phytosociology, also known as phytocoenosis, phytocoenology or simply plant sociology, is the study of groups of species of plant that are usually found together. Phytosociology aims to empirically describe the vegetative environment of a given territory. Primary productivity is a term used to describe the rate at which plants and other photosynthetic organisms produce organic compounds in an ecosystem. Net Primary Productivity is the rate of storage of organic matter in plant tissues in excess of the respiratory utilization by plants during the measurement period. Daily and annual net primary productivity of the dominant macrophytic vegetation were determined during 2016-2018. Alternanthera philoxeroides exhibited the highest daily net primary productivity with values ranging from 0.4 to 2.10 gm–2 day–1 in the first year(2016-2017) and 0.7 to 2.14 gm–2 day–1 in the second year(2017-2018). Echinochloa stagnina recorded daily net productivity values ranging from 0.14 to 2.2 gm–2 day–1 in the first year and 0.4 to 1.72 gm–2 day–1 in the second year. Ceratophyllum demersum, the present values varied from 0.10 to 1.52 gm–2 day–1 in the first year and 0.04 to 1.82 gm–2 day–1 in the second year. The daily net production of all species (combined) varied from 0.02 to 6.12 gm–2 day–1 and 0.14 to 8.40 gm–2 day–1 in the first and second year respectively. The total annual net production of all species (combined) varied from 680.64 to 890.13 gm–2 yr–1 and 701.49 to 838.45 gm–2 yr–1 in the first and second year respectively.
