Two laboratory based experiments were undertaken to evaluate the effect of various pH and salinity levels of soil on the germination and growth of common cattail (Typha latifolia L.) at the Department of Weed Science, University of Agriculture, Peshawar - Pakistan during November, 2016. The experiments were conducted using a completely randomized design. Experiment - 1 evaluated the effects of various pH levels of water and experiment - 2 evaluated various salinity levels of water on germination and shoot growth of common cattail. Results showed the pH levels to significantly affect seed germination and shoot growth of common cattail. Least seed germination (13.33 %) and least shoot growth (61.11 mm) was noted in water pH 10 and water pH 9. While highest seed germination (52.00 %) and highest shoot growth (86.67 mm) were recorded in water pH 4 and pH 5. In case of salinity the least seeds germination (0.10 %) and shoot growth (0.23 mm) was noted for the highest water salinity level (12 g L-1) followed by 10 g L-1. While maximum germination (80.67 %) and Shoot growth (74.44 mm) were observed in control and in minimum salinity (2 g L-1). It can be concluded that alkaline conditions (high pH) and high salinity highly affected germination and growth of common cattails. These results can be utilized in devising a non-chemical and environmentally safe and ecological control program for cattails management. This approach can be integrated with other weed control strategies for achieving maximum cattail control.
