Paulownia species comparative trials were carried out on three sites under irrigated conditions, viz; PFI, Peshawar, farmland at Garhi Saeed near Peshawar and Changa Manga irrigated plantation (Punjab). The data on diameter and height growth of trees of different Paulownia species after 5 years of planting indicated that Paulownia catalpifolia, P. fortune and P. elongate are faster growing tree species than the other Paulownia species tested in the trials. Fast growth rates, sparse crowns and deep root system of these species make them ideal for planting on farmlands in Pakistan.
