The aqueous extracts of five different trees Corymbia citriodora, Juglans regia, Alianthus altissima, Populus ciliata and Melia azadrach were applied on two selected wheat cultivars (Triticum aestivumL.) CM 301 approved variety V1 and a local variety V2. Aqueous extracts of 20g/200ml ratio concentration were prepared separately. The allelopathic effects on morphological parameters of wheat as well as reduction or enhancement ratio of wheat yield were studied. Five Treatments (T0, T1, T2, T3, T4, T5) for both varieties were arranged in completely randomized design (CRD) with three replications each. The morphological parameters were measured after 40 days of sowing. Data were subjected to analysis of variance through (ANOVA) and least significant differences (LSD) were found by using software (Statistix 8.1). All treatments showed remarkable positive and negative effects on the parameters under investigation. Significant difference was observed by parameters such as number of tillers (0.0183), root length (0.018), flag leaf length (0.0191), flag leaf width (0.0153), numbers of awns (0.0164) and grains weight (0.0193). Some parameters showed non-significant difference like number of spikeslets (0.0930) and numbers of grains (0.1518). While numbers of spike (0.3754), spike length (0.6088) and plant height (0.4461) showed highly non-significant growth. The study concludes that Juglans regia and Melia azedarach showed growth enhancing effect while Populus ciliata and Alianthus altissima strongly inhibit the growth and yield of both wheat varieties.

Wheat (Triticum aestivum L.) is the second largest cereal crop of the globe. In Pakistan, wheat crop is considered to be one of the * Corresponding author E-mail address: botanistjabeen@gmail.com most important cereal crops of the country (Marwat et al. 2013). According to an estimate of FAO Pakistan is the 9 th largest wheat producing country, accounting for 3.04% of the world wheat production from an area of 3.57% of the world.
