| dc.description.abstract | The present study was conducted on the “Floristic Composition and Diversity of Homegardens in Angara Block, Ranchi, Jharkhand” in the homegardens of 120 randomly selected sample household in four selected villages of Angara Block. The randomly selected villages are Singari, Gutidih, Janum and Rangamati Villages of Sursu, Tati, Angara and Nawagarh Panchayat respectively. Structure and diversity of homegardens were analyzed. A total of 101 plant species (21 trees, 10 shrubs, 13 saplings, 11 seedlings, 46 herbs) belonging to 43 families were recorded. In Angara Block, the most dominant family in tree layer were as Verbenaceae, Rhamnaceae, Anacardiaceae, Leguminosae and Moraceae. In sapling layer, Rhamnaceae, Verbenaceae and Anacardiaceae family were dominant. In seedling layer, most dominant family were Rhamnaceae, Verbenaceae, Moraceae and Myrtaceae. In shrubs layer, most dominanat family were Caricaceae, Moringaceae, Musaceae, Verbenaceae and Fabaceae. However, in herbs layer Poaceae, Brassicaceae, Solanaceae, Fabaceae, Araceae, cucurbitaceae and Malvaceae were most dominant family. Density of trees, saplings, seedlings, shrubs and herbs varies from 840 - 1390, 170 - 270, 100 - 140, 590 - 2110 and 42690 - 102320 ha-1 respectively. Of all woody species, Gamhar and Teak showed the highest Importance Value Index. Among fruit species Ber, Mango and Kathal showed the highest Importance Value Index. The highest IVI index indicated that these species are as dominated species. According to diversity indices of different villages of Angara Block, the Shannon index of tree, sapling, seedling, shrub and herb layers varies from 1.77 - 3.46, 1.91 - 2.77, 1.90 - 2.52, 0.72 - 2.27 and 3.01 - 4.22 respectively. Similarly, Simpson’s index of tree layer lies between 0.12 to 0.46, sapling layer 0.17 to 0.39, seedling layer 0.18 to 0.29, shrubs layer 0.25 to 0.54 and herb layer 0.08 to 0.21. Species Richness of the tree, sapling, seedling, shrub, herb layers are having between 1.38 - 2.22, 0.74 - 1.36, 0.65 - 1.04, 0.63 - 1.06, 1.77 - 3.00 respectively. Equitability ranges from 0.74-1.24 of tree layer, 1.07 -1.33 of sapling layer, 1.25 - 1.41 of seedling layer, 0.45 - 1.27 of shrub layer, 1.02 - 1.21 of herb layer. Beta diversity of tree layer varies from 1.31 - 1.91, sapling layer varies from 1.62-4.60, seedling layer varies from 1.83 - 2.75, shrub layer varies from 1.67 - 2.00 and in herbs layer varies from 1.39 - 2.42. Among the villages, the basal cover of trees, saplings, seedlings, shrubs and herbs varies from 25.40 to 39.26, 0.62 to 1.76, 0.05 to 0.62, 5.21 to 12.30, 37.52 to 64.98 (m2ha-1) respectively. A homegarden is designed to fulfill a wide array of functions and provide a range of benefits. These benefits are economic, ecological and cultural in nature. Homegardens contribute to floral diversity of landscape with owned plant biodiversity. The multistoried composition, high species diversity and domestication of wild plants in the system may help to conserve biodiversity of the area; they need to be considered for in situ conservation and development programme in future. Homegardens ensure crop diversification provide diversified products through low in amount but nutritious in nature. | en_US |
