Abstract

Phytosociological study was carried out to estimate the dominant of weed flora in garden land eco-system under varying climatic conditions. The survey was conducted at Sri Manakula Vinayagar Engineering College, experimental farm, Department of Agronomy, Madagadipet during 2023. Trianthem aprotulacastrum, Dactylenoium aegyptium, Phyllanthus niruri, Cleome viscosa, Physalis minima were the most densed weeds. Importance Value Index (IVI) computed for individual weed species at Madagadipet indicated that Trianthem aprotulocastrum was the predominant weed species with highest relative density of 32.9, relative frequency of 16 per cent and importance value Index (IVI) of 71.56. All other weed species were low in IVI and also rare in their occurrence with lesser frequency.
