Abstract: The present investigation entitled “Effect of Pre-sowing seed treatments on root growth and survival of ber (Zizyphus mauritiana L.)” the experiment was conducted at dry land horticulture field sirsod, College of Agriculture, Gwalior (M.P.) during 2018-19. The experiment was laid out in Completely Randomized Block Design with twelve treatments including control and replicated three times each. The twelve treatments consisting of three factors i.e. cow urine, water and plant growth regulators are T₀ (Control), T₁ (GA₃ @ 200 ppm for 24 hrs.), T₂ (GA₃ @ 300 ppm for 24 hrs.), T₃ (GA₃ @ 400 ppm for 24 hrs.), T₄ (NAA @ 50 ppm for 24 hrs.), T₅ (NAA @ 100 ppm for 24 hrs.), T₆ (NAA @ 200 ppm for 24 hrs.), T₇ (soaking in water for 24 hrs.), T₈ (soaking in water for 48 hrs.), T₉ (soaking in water for 72 hrs.), T₁₀ (Cow urine for 24 hrs.) and T₁₁ (Cow urine for 48 hrs.) T₁₂ (Cow urine for 72 hrs.) respectively were tested under the experiment. The observations were recorded on different aspects of root growth and survival viz. diameter of tap root The result of experiment revealed that the GA₃ @ 400 ppm for 24 hr (T₃) significantly reduce the mortality of plants and improved other parameter like diameter of tap root (0.68 mm) at 120 days after sowing, length of secondary root (4.43, 5.40 and 6.80 cm) at 60, 90 and 120 days after sowing, fresh weight of root and shoot (2.44 and 38.00 g), dry weight of root and shoot (1.85 and 26.33 g), and survival percentage (72.33%) of seedling at 120 days.
