The effects of aqueous extracts of Parthenium hysterophorus, Lantana camara and Jatropha curcas on the germination and seedling vigour of pigeon pea were investigated in a pot culture study conducted during 1999-2000. Crushed leaves were left for 24 h in distilled water at ratios of 1:10 and 1:15 (weed material: water). Pigeon pea seeds were then soaked in the extracts for 24 h. All extracts inhibited germination and seedling vigour to some degree.
