Abstract
The effect of fertiliser amendment was studied on biomass yield of grass Heteropogon contortus seeded on coal mine spoil. Two different doses of NPK fertiliser treatments were used along with control. The biomass production was significantly greater in fertilised plots compared to control plots. The response to fertilisation was comparatively greater for shoot biomass than root biomass. The root/shoot ratio was significantly greater in control plots in comparison to fertiliser amended plots.
