Sundramoorthy, S. | Kalra, A.
The poor understory vegetation of Acacia tortilis in different habitats suggests the existence of some kind of interference. The present investigations were carried out at Jodhpur site. The properties of soil beneath A. tortilis and P. cineraria did not differ significantly. The common understory plants of A. tortilis stand showed lower phytomass and higher phosphorus and potassium and nitrogen only in Boerhaavia diffusa and Gisekia phrnacioides than P. cineraria, indicating that no apparent competition exists. Soil extracts exhibit inhibitory effect on germination and seedling growth of all the crops. Leaves + stem leachate showed maximum inhibitory effect. Extracts exhibited higher inhibitory effect than the respective leachate. Concentration of extract and leachates were negatively correlated with germination and seedling growth. Sesame was affected most.
