Productivity of Different Types of Grass That is Produced on Ex Coal Mining Land

This study aims to determine the productivity of cut and carry grass in ex-coal mining land. Samples of soils for analysis at the Soil Research Institute were taken at three points. The design used was a Randomized Block Design (RBD), with plant varieties as treatment, namely Brachiaria brizantha cv. Mulato (A), Paspalum atratum (B), Panicum maximum cv Riversdale (C), Vetiver zizanoides (D), Panicum maximum cv Purple (E), Pennisetum purpureum cv Taiwan (F), Pennisetum purpureum cv Mott (G). The grass is planted in a 5 x 7 m plot, repeated three times over a planting distance of 0.5 x 0.5 m. The results of soil analysis showed that the organic matter content (%) for C, N was 1.67 and 0, 11, respectively, P and K content (%) was 0.04 and 0.43 and mineral (ppm) was for Ca, Mg, Na, Fe, Al, Mn, Cu, Zn and B : 0.08; 2.07; 0.60; 543.00; 24.33; 54.00 and 6.01. The results showed that plant varieties had a significant effect (P<0.05) on biomass production (gram plot -1 ), plant height (cm), and number of tillers. The highest biomass and height plant was Panicum maximum cv Purple and the highest number of tillers was Panicum maximum cv Riversdale. It is concluded that Panicum maximum cv Purple can be developed as cut and carry grass on ex-coal mining land.
