The effect of various scarification treatments on the germination of seeds of Desmodium ovalifolium (Prain) was studied. Following this a pot trial was conducted to evaluate the effects of lime, phosphorus and Rhizobium inovulation on the dry m atter yield, nodulation and the nitrogen and phosphorus content in the plant. Mechanical scarification by abrasion with sandpaper im proved germination by 30 percent. Liming up to the highest level o f 1000 kg/ha significantly increased dry m atter yield and nodulation. Phosphorus increased nodule num ber and phosphorus content in leaves and stems. Inoculation increased dry matter yield, nodulation and the levels o f nitrogen and phosphorus in the leaves and stems.
