Abstract
Due to the reduction in fertile land availability, ex coal-mining land can be used to produce animal feed plant (AFP). The objective of this study is to determine the productivity of grass for grazing areas planted in ex-coal mining land. Soil samples were chemically analyzed by the Soil Research Institute. The design used was a randomized block design (RBD), with plant varieties for treatment, namely B. humidicola (A), C. dactilon (B), P. notatum, (C) S. secundatum (D) and P. purpurium cv Mott (E). Plant grass each in plots measuring 5 x 7 m, and repeated three times with spacing of 0.5 x 0.5 m. The results showed that plant varieties had a significant effect (P <0.05) on the production of biomass (grams plot−1) and plant height (cm). The highest production and grass height were P. purpureum cv Mott with a production of 52,716.57 ± 6,366.12 g plot−1 and 104.26 ± 2.46 (cm). It is concluded that P. purpureum cv Mott has the potential to be developed as a pasture grass in ex-coal mining land.
