Abstract:
The experiment was laid out in a Completely Randomized Design with Factorial concept by three repetitions. The treatments comprised of eight level of pre-soaking treatments (S) viz., S₁ = GA₃ 500 ppm, S₂ = Thiourea 1%, S₃ = Urea 0.1%, S₄ = KNO₃ 0.1%, S₅ = Cow dung slurry: Water (1:10), S₆ = Cow urine: Water (1:10), S₇ = Soaking in hot water, S₈ = Control and three levels of environmental conditions (E) viz., E₁ = Open field, E₂ = Net house, E₃ = Polyhouse. Among eight pre-soaking treatments, S₁ (GA₃ 500 ppm) gave maximum height of seedling (33.41 cm), number of leaves per seedling (18.36), stem diameter (4.03 mm), internode length (2.18 cm), leaf area (43.30 cm²), fresh weight of seedling (8.27 gm), dry weight of seedling (3.05 gm), fresh weight of shoot (5.64 gm), seedling vigour index (4801.80), length of root (16.19 cm), number of primary roots (20.71), number of secondary roots (45.18), fresh weight of root (2.29 gm), dry weight of root (1.06 gm) and root: shoot ratio (0.42) at 90 DAS. Among three environmental conditions, E₃ (Polyhouse) gave maximum height of seedling (30.62 cm), number of leaves per seedling (17.02), stem diameter (3.68 mm), length of internode (2.18 cm), leaf area (37.94 cm²), fresh weight of seedling (8.25 gm), dry weight of seedling (3.00 gm), fresh weight of shoot (5.85 gm), seedling vigour index (4303.57), length of root (15.66 cm), number of primary roots (20.04), number of secondary roots (38.21), fresh weight of root (2.01 gm), dry weight of root (0.95 gm) and root: shoot ratio (0.43) at 90 DAS. Among different treatment combinations, maximum leaf area (46.19 cm²) was recorded in S₁E₃ (GA₃ 500 ppm + Polyhouse).
