ABSTRACT:
Phytosociological studies enable the plant scientist to have more insight into the nature of such plant. The phytosociological study of weed flora from three sites in Imo State University, Owerri, Imo State was undertaken. The research was done between the month of July and September, 2016. The weeds grow abundantly in the areas under tropical climate and supported by a sandy-loam soil. The data indicated that Panicum maximum, Tridax procumbens and Eragrotis ciliaris are the most dominant species identified in the area. Phytosociological investigation showed a Panicum – Tridax – Eragrotis Plant community. Panicum was positively associated with Tridax procumbens, Eragrotis ciliaris and Maricus alternifolus. The interrelationship of Panicum maximum (Jacq) was thus determined. This study therefore is a contribution to the general ecology of the plant.
Key words: Physiological study: Weed flora: Abandoned farmland: Panicum-Tridax-Eragrotis Plant community.
