Abstract
Abstract: The main objective of this study was to assess the status, composition and diversity of plants in a rural village homegardens with the help of socio economic factors of households. The study was carried out in Swamithoppe village, Kanyakumari district, Tamil Nadu, India, in 121 randomly selected homegardens were measured. Complex plant species inventories were carried out to assess the number and abundance of plant species (i.e., all useful plant species) and ornamentals. All gardeners were individually interviewed about homegarden management and plant utilization, among other information. In addition, to plant species information, species diversity, richness, evenness and dominance indices were also calculated. In Swamithoppe village, the homegarden area varied from 20.23m2 to 627.28m2 with an average of 73.21m2 to 519.36m2. In the HG survey, a total of 119 plant species comes under 108 genus belongs to 58 families with a total number of individual is 3540 were recorded. The number species recorded ranged from2 to 23/HG species with an average of 8.30 to 9.24species/HG. The species density varied from1.65/100m2 to 64.26/100m2 with an average of 2.58 to 13.84/100m2. The number of individuals of plant species noted in the homegarden varied from 7 to 78nos with an average of 24.75 to 66.67nos The overall, plant diversity in homegarden based on number of individuals ranged from9.88 to 143.35/100m2 with an average of 12.99 to 40.06/100m2.In plant overall HGs shows a total of 119 species with 3540 individuals in 121 HGs and the plants distributed in HGs ranged from 3 to 22 HGs with an average of 9.39 HG. Out of 58 botanical families recorded Euphorbiaceae is one of the most represented family having 6 genes, 10 species with 245 individuals with an average of 2450 individuals per species and the maximum diversity (H’=0.342) and low Simpson’s diversity (λ=0.00052) as compared to other families. Among the top 10 HG species, Cocos nucifera shows maximum no of individuals (162) with an average of 7.36/HG and found in 22 HGs. The distribution pattern of HG plants indicate that maximum no of plants found in herbs (36.13%) in life form, earthen plants (77.31%) in habitat, cultivated plants(74.79%)in growth condition, whole plant utilization (39.50%) in useful parts and ornamental use plants (31.93%)in uses category. The diversity indices estimated for over on home garden plants as H’=4.627, (Shannon diversity), species richness (R=14.440), species evenness (E=0.968), and Simpson’s diversity (λ=0.0109). Keywords: Homegardens, Plant structure, Plant composition and distribution, Plant diversity, Swamithoppe village, Kanyakumari.
