Organic fertilizers are a source of very useful for improving soil quality and yield of various crops. Vermicompost and derived products such as compost tea as a product of urban waste recycling with proper physicochemical features, can play an effective role in plant growth and development and also in reducing harmful effects of various environmental stresses on plants. In order to evaluate the effects of compost tea on some morphological characteristics of lentil under water deficit stress, a factorial experiment was conducted factorial based on completely randomized design with three replications in 2015 at the Khatam Alanbia University of Behbahan. The first factor was different levels of compost tea including, 0 (control), 25, 50 and 75 volumetric percentage and second factor was water stress in three levels, 25, 50 and 100 field of capacity. Foliar application of compost tea was applied 3 times during plant growth stage (seedling, flowering and podding). Results showed that there was significant difference (p 0.01) between vermicompost levels concentrations regarding to plant height, number of branches, leaf number per pod, root and shoot dry weight, taproot length, root diameter, root volume, root area and number of pod. Foliar application of compost tea, for most traits of shoot compared to the control group increased significantly but in the root characteristics under moderate and severe water stress, there was no significant difference between treatments. Considering that, compost tea contains many of the growth regulators and micro and macro element will be introduced as an appropriate fertilizer to increase morphological parameters.
