Abstract
The research trial was conducted under laboratory conditions at Department of Agronomy, Faculty of
Agriculture, Gomal University, Dera Ismail Khan, Pakistan in order to study phytotoxic effects of
mesquite (Prosopis juliflora) aqueous extract taken from its leaves, stem and root on germination and
seedling growth of wheat. There were five treatments viz. 100g, 200g, 300g, and 400g aqueous leaves,
stem and root extract of mesquite including tap water as control. It was evident from the results that
by using different concentrations of aqueous extract of mesquite, seed germination and seedling
growth of wheat were inhibited. The maximum reduction in germination and seedling growth was
noted by applying higher concentration (400g) of aqueous extracts of mesquite. Hence, it is concluded
that seed germination and seedling growth of wheat is inhibited due to presence of water soluble
allelochemicals in aqueous leaves, stem and root extracts of mesquite at 400 g for 72 hours. These
allelochemicals have negative effects on growth and development of wheat. It is, therefore,
recommended not to cultivate wheat crop near the mesquite.
