Abstract This work aimed to study the individual effect of Phosphorus and Potassium at different rates on the growth, sugars, hydrocarbon extracts and chlorophylls of Pedilanthus tithymaloides a low molecular weight hydrocarbon-yielding plant which is important for its pharmacological properties. Data clearly showed that a gradual increase in potassium fertiliser had a significant gradual increase in plant growth; per cent dry weight, hexane extractable, sugars and chlorophyll contents of the plant as compared to untreated plants. Thus, a positive correlation was observed in the increase in growth and hexane extractable. Muriate of potash at the rate of 120 kg/ha was found to be the best suited for all the parameters. Phosphorus, however, did not show much increase in growth. 90 kg/ha phosphorus (P2O5) was found to be optimum for the growth, biocrude content, sugars and chlorophyll contents.
