| ABSTRACT: Two-year field experiments were conducted to investigate the phytotoxicity of mesquite (Prosopis juliflora) on weed control and yield of wheat in 2013-14 and 2014-15. Mesquite aqueous extracts were prepared with 10, 20, 30 and 40% concentration of leaves, stems, and roots and were compared with tap water (control). These experiments were laid out in a completely randomized block design with four replications. All parameters (weed density, fresh weed biomass, dry weed biomass, chlorophyll content, leaf area index, leaf area duration, crop growth rate, net assimilation rate, plant height and number of tillers) were significantly reduced by applying the mesquite extracts. Among different concentrations, the maximum level (40%) of all three plant... |

| ABSTRACT: The present research work was undertaken to find out the phytotoxic effects of different concentrations of aqueous extracts of leaves, stems and root of milkweed (Calotropis procera) in the Agronomic Research Area of Department of Agronomy, Faculty of Agriculture, Gomal University, Dera Ismail Khan, Khyber Pakhtunkhwa (KPK), Pakistan during 2013-14 and 2014-15. The treatments consisted of different concentrations of aqueous leaf, stem and root extracts (10, 20, 30 and 40%) of milkweed, which were compared with tap water (control). The results showed that the reduction of all studied parameters, including weeds, growth and yield of wheat was proportional to the concentration of aqueous extracts of milkweed in use. The level of inhibition was... |
