Abstract

An experiment was conducted to know the effect of organic manures, bio-fertilizers and inorganic fertilizer on seedling growth of Melia azedarach. The growth parameters (seedling height, collar diameter, number of leaves, leaf area, ischolar_main length and ischolar_main-shoot ratio) and biomass parameters (fresh shoot and ischolar_main, dry shoot and ischolar_main and total fresh and dry shoot and ischolar_main) were found maximum in vermicompost (30 g/seedling) compared to FYM (50 g/seedling). Among the bio-fertilizers, Azospirillum + PSB recorded maximum seedling height, number of leaves, leaf area, ischolar_main length, fresh weight of shoot and ischolar_main, dry weight of shoot and ischolar_main and total fresh and dry weight compared to Azospirillum alone, PSB alone and no bio-fertilizer. Among the inorganic fertilizers, 1.0 g NPK found better in recording all the parameters compared to 0.5 g NPK and no NPK/seedling. Among the interactions of organic manures, bio-fertilizers and inorganic fertilizers, combination of vermicompost + PSB + 1.0 g NPK has recorded maximum seedling height (154.6 cm), collar diameter (8.53 mm) and leaf area (126.0 cm²), fresh ischolar_main weight (20.01 g), total fresh weight (75.84 g), ischolar_main dry weight (9.68 g) and total dry weight (35.43 g).
