Response of pre-sowing seed treatments on growth of Ber (Zizyphus mauritiana L.)

Abstract

The present investigation entitled “Response of Pre-sowing seed treatments on growth 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 Days taken to start germination (9.00), Days taken to 50% germination (13.00), Germination percent (73.33% and 76.00%) at 30 and 60 DAS, Height of seedling (29.67, 34.67 and 39.00 cm) at 60, 90 and 120 DAS, Number of leaves per seedling (33.00, 55.00 and 67.33) at 60, 90 and 120 DAS, Fresh weight of shoot (38.00 g) at 120 DAS and Dry weight of shoot (26.33 g) at 120 DAS.
