The research was conducted during 2019-20 in flowering seasons. Local names, habits, parts used and medicinal uses of plants were documented by questioning the residents of dissimilar age groups and herbal experts. A total of 162 medicinal plant species belonging to 129 genera and 49 families were recorded in the area. The majority of flora was herbaceous followed by trees, shrubs and creepers. The most frequent part used were leaves (43.83) followed by other plants' parts. The ethnobotanical study depicted that 143 species were fodder, followed by fuel (45 spp), timber (14 spp), thatching (3 spp), fruits (20 spp), vegetables (18 spp), ornamental (11 spp), medicinal (42 spp) and insect attractant 8 species. Various diseases like asthma, constipation, fever, dysentery, itches, skin diseases, cough, and vomiting are mostly treated with medicinal plants. The dominant life form class is Therophytes 87 (53.70%) while the lowest was Geophyte 10 (6.17%). Mesophyll shows the dominant leaf size class ie 48 (29.62%) while the lowest class of leaf size is Megaphyll is 6 (3.12%). The proximate composition of selected plants clarified that the highest dry matter, crude protein and moisture content were present in Kochia indica, highest percent ash and crude fiber were present in Torilis leptophylla. Minerals contents were observed in all selected plant species. Highest carbon content was present in Aerva javanica (65.49%), highest nitrogen content was in Amaranthus viridis (12.02%) oxygen (42.49%) and magnesium (0.17%) content were highest in Kochia indica. Torilis leptophylla and Cichorium intybus have no magnesium content. Potassium contents was highest in Cichorium intybus (3.80%) and highest calcium content was in Amaranthus viridis (0.53%). Sodium was present only in Amaranthus viridis (0.03%). Soil texture class showed that soil was mostly silty loam with 8.0 to 8.3 pH and 0.10 to 0.17 (DSM-1) electrical conductivity. Total soluble salts were in the range of 0.032 to 0.054%. CaCO3 was with a range of 6.50 to 9.0. 0.62 to 0.89% organic matter content was also detected.
