Abstract: Gliricidia sepium is promising multipurpose, leguminous, fast growing tree for agroforestry and also used as fuel wood, fodder and green manuring. This study was carried out to find out germination behavior and effects of different pre-sowing seed treatments on growth of gliricidia. In this experiment, gliricidia seeds were treated with six pre-sowing treatments viz. control-T₀, hot water treatment-T₁ (80 °C), cold water treatment-T₂, cow dung slurry treatment-T₃, H₂SO₄ treatment-T₄ (98% for 3 min.) & knuckling-T₅ and the effect on germination, growth and vigour was studied. The experiment was carried out in research farm, RGSC-BHU, Barkachha, Mirzapur India with five replications in RBD. The H₂SO₄ treatment provided the highest seed germination %, germination energy, number of nodules and vigour index while knuckling provided highest no. of leaves, shoot height, root length total seedling length, collar diameter and biomass accumulation which were at par with control and soaking in water. Germination was completely hindered in case of hot water treatment. As no significant difference found among control, knuckling and acid treatment, it was concluded that no treatment can significantly enhance germination and vigour in gliricidia but cow dung slurry treatment performed significantly inferior to control.
