Productivity of five herbaceous legumes species in the post tin mining area as forage sources in Bangka Island

Abstract

The objective of this study was to determine the adaptability of some herbaceous legumes grown on the soil as source of forage in post tin mining areas. The forage legumes tested were Arachis pintoi, Clitoria ternatea, Stylosanthes guiyanensis, Centrosema pascuorum cv Bundey and Lab-lab purpureus. The experiment was designed for a randomized block of five treatments and three replications. The plants were grown in plots of 5 m x 4 m with planting distance 0.5 m x 0.5 m. Plants have been pruned every 2 months at forage production. Parameter measures the production, quality and capacity of forage. Analysis of forage nutrition and digestibility in the laboratory of dry matter and organic matter. The growth rate for transplantation of three legumes A. pintoi, C. ternatea and S. guiyanensis, was 100%. The highest total forage for one year was S. guiyanensis 514.29 kg plot-1 with a carrying capacity of 12.33 AU (animal unit) and 74.02% dry matter digestibility and 73.96% organic matter. This study indicated that three (3) species C. ternatea, S. guiyanensis and A. pintoi showed an average high-life ability of up to 100%. In general, the type of legume selected in this study showed good adaptability.
