Abstract
An experiment was conducted to determine the allelopathic effects of leaves of different trees including Juglans regia, Melia azedarach, and Ailanthus altissima, on the germination of two different wheat varieties i.e., traditional and approved. Significant variation was noticed among the treatments in germination attributes. Maximum radical length was observed in both the wheat varieties due to aqueous leaf extract treatments of J. regia while minimum radical length was observed in both the wheat varieties by the aqueous leaf extract of M. azedarach. While maximum plumule length in both wheat varieties was also revealed by the aqueous leaf extract of J. regia while minimum plumule length was observed by extract of M. azedarach. Furthermore, the allelopathic effect of M. azedarach was observed to have great r than A. altissima on the germination and growth of wheat. it is concluded that leaves of J. regia can be used as bio fertilizer due to its growth enhancing effect while leaves of M. azedarach and A. altissima contains allelo-chemicals that strongly inhibit the seed germination and reduce plumule and radical length of wheat.
